Nutanix AHV (Hypervisor) Update Released

Fresh off the press, is an updated version of the Nutanix hypervisor, AHV. Today we released AHV-20160925.43. Features include broader support for the AOS 5.0.x family, and a tech preview feature of hot plugging memory and CPU on VMs. A number of bug fixes were also incorporated. Noteworthy, is a network stack issue that has been fixed. This issue could be experienced by any customer, so upgrading is encouraged.

If you are using AHV, you are encouraged to check out the release notes here. AHV is 1-click upgrade enabled, so you can easily update your cluster in an automated fashion with no VM downtime.

 

Critical Zerto 5.0 update for Nutanix customers

If you are a Nutanix customer, and using Zerto, Zerto has release a very critical patch. Unpatched, the bug could result in data integrity issues. This has been seen in the field, particularly with Microsoft SQL. So it’s very imperative that you review the Zerto release notes and upgrade to Zerto 5.0 U2 ASAP.

The issue manifests itself during CVM failover operations and result in lost writes.  These failover operations are normally transparent to the guest, and in no way interrupt the normal I/O data path. The Nutanix business critical apps team was able to reproduce the issue in house at will, and confirmed Zerto 5.0 U2 has resolved the issue. Zerto is a great partner, and they were extremely helpful in resolving this issue. The issue is not exclusive to SQL, but is more readily apparent since DBAs do routine integrity checks which will fail if the bug has been triggered.

I do not know if versions prior to 5.0 U2 (such as the 4.x version) will receive the patch. Check with your Zerto account team. If the patch won’t be back ported, then you need to plan on upgrading to 5.0 U2 ASAP. We have many joint customers, that absolutely love the Zerto features coupled with Nutanix simplicity.

My boss, Michael Webster, also has a write up about this issue which you can find here.

Nutanix AOS 5.0.1 enabled for 1-click upgrades

Earlier this year Nutanix released AOS 5.0, which contained dozens and dozens of new features and enhancements. As Nutanix customers know, we have 1-click upgrades for AOS. Prism will automatically notify you when there is an updated AOS version available. While customers can immediately download new releases from the portal and use 1-click upgrades, Nutanix delays the automatic notification on major releases until the first maintenance release comes out. This allows customers that want the absolute latest code to download it manually, but gives more conservative customers time for the release to mature before it’s automatically downloaded by Prism.

As of this week, AOS 5.0.1 will now automatically appear in Prism as a 1-click upgrade option. So if you have been holding off on AOS 5.0 until the first maintenance release, you need not wait any longer. Check Prism for software updates and you should see AOS 5.0.1 available.

Released: Nutanix AOS 4.7.5 and other tools

Nutanix has released an updated version of the AOS 4.7 family, which is now bumped up to AOS 4.7.5  If you have already upgraded to AOS 5.0.x, which came out earlier this year, you can ignore this post. Those of you with Nutanix support portal access can download the 4.7.5 release notes here. Since this is a minor release, it’s mostly bug fixes and minor new features. One new feature that is noteworthy, is a new 1-click SATA-DOM firmware upgrade feature for Nutanix NX and Dell XC platforms with hypervisors other than Hyper-V. Nutanix takes security extremely seriously, and as such, this update addresses a variety of CVEs. So even if the new features or other bug fixes don’t seem all that interesting, personally I would recommend the upgrade due to the security patches.

In addition to AOS 4.7.5, minor revs to related products are out as well:

  • Prism Central 4.7.5 can be downloaded here. The Prism Central release notes are available here and the Upgrade Guide is available here.
  • Nutanix Cluster Check (NCC) is now at version 3.0.0.2. It can be downloaded here and the release notes can be found here.
  • Foundation 3.7, which is the Nutanix Cluster deployment tool, is now out. Download Foundation 3.7 here and read the release notes here.
  • AHV version 20160601.50 which can be downloaded here and the upgrade instructions can be found here.

Nutanix customers really enjoy the 1-click upgrade for many components, so when we release a new batch like this, it takes minimal time to update the environment. And no VM downtime is required, which makes scheduling maintenance windows easier.

Nutanix AOS 4.7 Immediately Available

What’s New in AOS 4.7? Some of these enhancements were announced at .Next last week. Here’s a full list of what’s new in AOS 4.7. It is available for immediate download on the Nutanix support portal.

Acropolis Block Services

Acropolis Block Services (ABS) provides highly available and high performance block storage as iSCSI LUNs to clients. Clients can be non-Nutanix servers external to the cluster or guest VMs internal or external to the cluster, with the cluster block storage configured as one or more volume groups. This block storage acts as the iSCSI target for client Windows or Linux operating systems running on a bare metal server or as guest VMs using iSCSI initiators from within the client operating systems.

Cluster Resiliency (Degraded Node Detection)

Nutanix Engineering has introduced capabilities in AOS to identify partially available nodes and prevent them from affecting cluster availability. It can detect if a node is experiencing  network latency issues, disk or memory errors, or other issue that would affect cluster performance. AOS marks the node as degraded, places it in maintenance mode, and raises an alert to indicate its status. The node will be prevented from participating in cluster operations and cluster operations will continue. The node can rejoin the cluster once the issue is fixed. This feature is disabled by default and customers are advised to contact Nutanix Support to enable and use it. Reference internal Knowledge Base Article 3361.

Docker Container Support

The Nutanix volume plug-in for Docker enables Docker deployments to be integrated with external storage systems, in this case the Nutanix distributed file system (NDFS), and enable data volumes to persist beyond the lifetime of a single container machine host.

1-click HBA Disk Controller Firmware

The LSI host bus adapter/controller (HBA) 1-click firmware upgrade feature is available for Acropolis hypervisor (AHV) and ESXi hypervisor host environments running on NXxxxx G4 (Haswell) or NX-xxxx-G5 (Broadwell) platforms only.

In-Place Hypervisor Conversion

Previously tech preview, this 1-click feature available through the Prism web console allows you to convert your cluster from using ESXi hosts to using AHV hosts. Guest VMs are converted to the hypervisor target format, and cluster network configurations are stored and then restored as part of the conversion process. Note: This feature converts your existing ESXi cluster to an AHV cluster. You cannot start the conversion process on the AHV cluster.

Intel Broadwell Architecture

Support for platforms using the Intel Broadwell CPU and architecture.

Internationalization (i18n)

Non-ASCII user defined values (for example, entity names, descriptions, and so on) are supported in UTF-8. For the list of supported and unsupported entities and to change language settings to Simplified Chinese, see the Prism Web Console Guide.

Newly-supported platforms

Support for Nutanix Xpress platforms such as the SX-1065-G5. See the Xpress Series Compatibility Matrix in Release Notes | NX-series Hardware on page 22. Support for Lenovo Converged HX Series

Prism Central

Enhanced Prism Central Explore tab usability with custom page sizing, custom Focus views, and easier select options.

Security

Nutanix Security Engineering and Research Team (nSERT) has identified existing vulnerabilities associated with certain security concerns and this release addresses these vulnerabilities. See Resolved Issues | AOS 4.7 on page 6 of Release Notes for details.

Simplified SSD breakfix procedures for Hyper-V

Support for single SSD replacement procedures for Hyper-V clusters.

Support for the Microsoft Cloud Platform System (CPS)

Support for the Microsoft Cloud Platform System (CPS), which bundles Windows Server 2012 R2, System Center 2012 R2 and Windows Azure Pack for easier hybrid cloud configuration. Nutanix offers the CPS Standard version preinstalled on nodes from the factory.

TRIM Support for Acropolis File Services

For Acropolis File Services, the Prism Web Console previously could not show accurate storage consumption as it did not show deleted data. Now, Acropolis File Services introduces TRIM and thin provisioning with 4.7 for better storage. TRIM is enabled by default and communicates free block information to the Prism Web Console from TRIM. AOS then performs storage distribution for better storage consumption.

Whitelist Prism Central and Prism Element to bypass proxy servers

Prism Central and AOS 4.6.2 introduce new nCLI options ncli http-proxy add-to-whitelist / ncli http-proxy delete-from-whitelist. Use the ncli http-proxy add-to-whitelist command to bypass a proxy server used by a Prism Central-managed cluster and allow network traffic between Prism Central and the cluster. Previously, if you attempted to register a cluster that implemented a proxy server, the registration failed. The Prism Central Guide describes how to configure this use case with these new commands.

.Next 2016: Day 1 First General Session

Here we are, at the second Nutanix .Next conference! Last year it was in beautiful Miami, and this year it’s in hot Las Vegas. I’m not sure which is hotter, the weather or our announcements. Like last year, this event is sold out and more than double the size! I’ll be live blogging the sessions that I’m attending this year. As always, then are real-time notes and don’t have time to take slide photos and insert them in the blog posts. But I try and capture the essence of each session

All of the attending Nutanix NTCs are lined up on stage and several of them do introductions.

Howard Ting takes stage.

In our first year we expected 500 to 700 attendees, we ended up over 960 people. This year the goal was 2000, and our registration total is 2,500.

Howard covers some of our great customers, such as airlines that run critical airline operations, a company that prints billions of coupons on Nutanix, or hospitals running critical operations on Nutanix. “You’ll love Nutanix”. “Love” is not a word you hear much about IT infrastructure. Nutanix is on a journey to build the enterprise cloud. In reality, only 7% of companies have built a true private cloud. Most think they have just by virtualizing.

Nutanix: Enterprise  Cloud Platform

Dheeraj Pandey (CEO/Founder) takes the stage

The Growth Paradox: Most executives cite internal factors, not market forces, for what slows growth.

Founder’s mentality: Insurgent mission, owner mindset, obsession with the front line

Ambition, Attention-to-detail

One click upgrades: One click mover

Dheeraj talks about Community Edition and brings Richardarsenian on stage. They show off a drone which has Nutanix community edition running and controlling it.

DataGravity: Data driven security

“Coming together is a beginning; keeping together is progress; working together is success.”

Sunil Potti takes the stage

Nutanix wants to be the AWS for the enterprise – Enterprise cloud platform on my terms

Shipping very shortly  will be v4.7 and Asterix

Within one week of the 4.6 release, 500 clusters were upgraded. After 100 days, nearly 50% of all clusters were upgraded.

We support: Mainstream virtual apps, now all virtual apps,

Sunil shows a performance graph, where customers got a 4x improvement for free just via software upgrades.

For Broadwell servers all models now support all flash configurations. Or hybrid, your choice.

Michael Tempora from Vonage comes on stage. They are rapidly expanding into the business VoIP sector. Vonage cloud platform is powered by Nutanix.

Why stop a virtual workloads? Nutanix now supports bare metal via Acropolis Block Services featured in 4.7. Run 3 tier apps entirely on Nutanix. 200,000 random Oracle IOs in 2U.

Demos Citrix on AHV with MCS integration and Acropolis File Services (AFS). They also show the cluster running heavy SQL loads, plus bare metal Oracle workloads using ABS. The true power of a unified fabric.

15% of Nutanix clusters now running AHV

Jake Yang, Nasdaq Global Infrastructure director. Believes the hypervisor is now a commodity. Big adoption of AHV.

New: Acropolis Container Services. A native container platform, Docker support, persistent portable storage volumes.

One click upgrades: BIOS, BMC, Storage controller, disks, hypervisor, AOS, NCC, Foundation

Asterisk: 1-click self-service. Shows a demo of the new “Self-Service” tab in PRISM.

On demand Nutanix Community Edition: Can launch a public cloud hosted CE cluster and use for free for 2 hours.

Asterisk: You will no longer need to login to vCenter to manage ESXi. PRISM will support multi-hypervisor support.

T-Mobile’s Kevin Luu, Sr. Director Infrastructure and DevOps to talk Nutanix.

AOS 4.7: Microsoft CPS on Nutanix. Factory installed, deployed in hours, 1 click upgrades, full stack support from Nutanix.

Clutter-free organization: New filtering, labels, and great new search features

Asterisk: Visualization of the network. An all new network view coming to PRISM.

 

VMworld 2015: Nutanix Customer Panel

Session SDDC6827

Note: This was a panel discussion, so I tried to transcribe as much as I could. Please forgive any typos or bad English. I’m immediately publishing after the session was over.

Josh Odgers – Nutanix
Sachin Chheda – Nutanix
Bob – Hallmark business connections (Hallmark cards)
George – Perth Radiology
Matt – Lang’s building supplies

What is holding virtualization back?

  • 3-tier model is complex to manage
  • Costly to scale
  • Performance bottleneck

Making complex simple – Making Simple Invisible – like Uber
The best infrastructure is that which is invisible
Our mission: Deliver invisible infrastructure.
1750+ customers, 70 countries, 6 continents, 1000+ employees
IDC declares Nutanix has 52% of the hyperconverged market

Nutanix Extreme Computing Platform – Eliminates separate SAN and NAS arrays.

Sachin: So Bob, can you give us some background how you came to Nutanix?
Bob: Been in IT for 30 years and looking for cheaper, faster, better. I’m associated with leading edge IT. Introduced a few years ago to Hyperconverged. Did a Nutanix pilot for SQL, and it went extremely well.

George: I work for an imaging provider in Perth, across multiple sites. About a year ago we were looking for a new solution, our 3 tier solution was getting old and tired. Looked at hyperconverged and it looked simpler and easier to use. Our first workloads moved to Nutanix was SQL and Exchange.

Matt – We are a manufacturer and were introduced to hyperconverged after we missed a prior IT refresh cycle. So we had to do a large refresh, including desktops and infrastructure. We looked at 3 tier, but hyperconverged ticked all the boxes. Hypeconverged is rock solid platform, easy to scale, and we can grow our business as we require.

Sachin: What were some of the things you saw in hyperconverged?

Bob: The value prop of hyperconverged is doing more with less staff, and is very streamlined. Cost is obviously a huge issue, but more importantly the OPEX. Reduced complexity and reduced cost.

Sachin: Could you walk us through some goals?We

Bob: We were having performance issues with our analytics on our 3-tier stack.  We brought in Microsoft BI specialists, and they recommended a highly expensive stack to make the solution worked. So we had to look out of the box, and arrived at hyperconverged and Nutanix.

George: A good friend works for another company, and his better half worked for a storage company. I got honest feedback about storage technologies. We had fiber channel technology that we replaced. We needed something higher density and easier to look after. That’s why we went down the Nutanix path.

Matt: For me efficiency is critical. Less about IT and more about OT (operational technology). Nutanix lets me spend more time on my business and less on IT. For every hour I spend babysitting the infrastructure the less I spend on business. Management wants to see IT as a profit center, not as a cost center. Nutanix has always allowed me to say “yes”. We can deploy apps very quickly, like a dev environment. We can easily expand a cluster in 15 minutes. The hardest part about Nutanix is racking it, seriously. We have to be very keen on costs, and OPEX costs are top of mind. Other vendors could compete on acquisition cost, but they can’t compete on simplicity. We also use it for VDI, and have the NVIDIA grid cards in the NX-7000 series. We have users all over the world using the solution.

Sachin: So an Australian company with global workforce. Josh, let’s get more on the technical details.

Josh: We’ve spent a lot of time talking about business challenges. Business people don’t care about VCDX or SSD drives. This customer had to scale their storage and they could use the Nutanix storage only nodes.

George: We were talking to application owners and they were stating we needed SAN or NAS. But when you are virtualized, it doesn’t matter. We’ve had massive success with Nutanix.

Sachin: You started off with SQL server and BI, but have since expanded your environment.

Bob: We started with the BI stack, and a way to get Nutanix in. I wanted to get Nutanix in the door to show the value of the solution. Our DevOps teams came to me and our C# build times were creeping up to 2 hours. We need a faster solution. So we moved the workload to the Nutanix cluster. Build times reduced to 22 minutes, and that’s real time developers can dedicate to coding instead of waiting on builds to complete. We put that in front of senior leadership, and told them it improved productivity. It enabled me to create a 3 year vision on replacing our entire infrastructure with Nutanix. This will take 3 years to get there, but we will have active/active sites. It allows for better performance, and gives us opportunities to be agile. We understand the concept of DevOps, and want to remove obstacles through technology. This gives more time to sales and DevOps time to do their job.

Sachin: When you went to this new process, what were some of the new features you wanted. DR, cloning, etc.

Bob: We love VMware and what they let us do. But we were looking for a new level of flexibility. But we wanted DR and near-realtime data replication and reduce RPOs to near zero. In addition, and we were really excited about hypervisor choice. We are excited about the possibility of using multiple hypervisors, and even include the Nutanix Acropolis hypervisor. Choice is imperative. If you are an engineer and specialize in storage, your career is limited. Get an engineer to think about thought leadership.

Sachin: So Josh talk about how to access Nutanix. We have PRISM and our APIs.

Josh: I’ve spoken with a lot of service providers and they like PRISM. But they want to automate. Everything you can do in PRISM, you can access via the APIs. This was key for developing our platform.

Sachin: So George, I have a question from twitter. So you have the concept of mixing and matching workloads in your environment. What were your criteria for doing that?

George: Our image storage app need a lot of IOPs, including archival disk requirements.  We have both compute and storage nodes in the same cluster. It’s simple to consume. We didn’t have to hire a storage sysadmin. They can easily consume the cluster resources. Allows rapid development and deployment.

Sachin: Tell us about ongoing management.

Matt: Last year I was flying to VMworld, and I saw wifi on the plane and saw a new NOS update. So I did a cluster update from the air. I’ve never done that with infrastructure before. Maintenance windows are unacceptable. The NOS upgrade didn’t require any downtime. Nutanix and the resilience factor are great. We want the business to always be on, and don’t want to see the business see any performance degradations. Nutanix fails in gracefull manner, and it will self heals. We script everything, and we are to the point where we don’t even provision new users manually. We are very agile and fast. Our ERP is on Nutanix as well. We started with VDI, but that went so well we expanded the workloads. We were able to migrate new workloads in minutes, without months of planning. We get into IT because we like new toys.

Sachin: So Matt, so the common thing we come across are the business angles. This is different and is this what infrastructure should do?

Matt: Absolutely. We want to worry about the business and not the infrastructure.

Bob: IT should not be a cost center, but should be cost neutral. We are looking at scaling out Nutanix as a service, and looking to move other Hallmark subsidiaries to Nutanix. We own Crayola, which is a large business. We started with SQL BI stack, and that was very successful. Our biggest challenge was the sheer volume of apps that we needed to move to Nutanix. What we have now is all the BI and client web app tier are on Nutanix. We do large content management database, and that is based on Mongo running on Nutanix. We also have Oracle 10g running on Nutanix.

Sachin: Josh you are very active in the community. You mentor a lot of VCDX mentoring. What advice would you give to those looking at 3-tier?

Josh: The goal of the VCDX/NPX is all about meeting business requirements. It’s not about technical decision. It’s not about cool toys. Its about mapping business requirements to technical requirements. Keep moving forward and don’t get stale. Don’t bet your job on a single role. We aim to make IT staff more valuable by expanding their skillset.

George: We are looking for our IT staff to be more business oriented. We don’t want our staff just watching blinking lights. We look at what process are in place, and try to fit IT solutions into that framework. We developed a timesheet solution in 6 months, without worrying about the infrastructure.

Audience question: Can you tell us about support and how good it is? Our POC SEs are spot-on.

Matt: Nutanix support is even better than the product. We had a small problem, and called them up. They blew my mind. There aren’t any level 1 or level 2 guys, they are level 3 guys. The guys you get can solve your problems.

Josh: We had a customer that had four hardware failures in a short period. No downtime or data loss. We shipped them new hardware of course. I did the design for them, so I flew to their site at no cost just to put their mind at ease.

Audience question: Can you talk about your old storage arrays, and we have a bunch of storage admins that are nervous about changing platforms.

Bob: We used compellent. We would have had to upgrade controllers and disks. It would have cost us 500K to upgrade, and it was a forklift upgrade. The hyperconverged upgrade only cost 200K. We like the linear scalability. We could use any storage vendor, but don’t like the forklift upgrades and all that cost.

Matt: You can achieve the same outcome using traditional storage, But you don’t do it in the same time, and it will be more complex. We don’t like forklift upgrades. With Nutanix you eliminate forklift upgrades.

Josh: With Nutanix all writes always hit SSD. So your writes are always consistent. Ya these guys ran SQL on Nutanix first, which is somewhat unheard of.

Nutanix Acropolis is Citrix Ready

Just over two months ago Nutanix took the covers off our Acropolis hypervisor at our .Next Conference in Miami. Even prior to that announcement, Nutanix has been working behind the scenes with a number of close partners for ecosystem support. I’m very proud to announce that today that Citrix XenDesktop and XenApp customers can use the Acropolis Hypervisor as it was Certified as Citrix Ready! The hypervisor itself is free, and can be run on any Nutanix platform.

CitrixReadyCosts are always closely scrutinized when deploying VDI, so taking the hypervisor cost out of the equation is always a plus. Nutanix has a number of VDI features like shadow clones which really make hosting desktops a rock solid solution. Plus you can linearly scale out one node at time, as your VDI population increases.

With today’s announcement, if you are customer and want to run XenDesktop or XenApp hosted VDI on Nutanix both you can have the confidence of Citrix Ready certification. This partnership will roll out in phases, and this is just the first phase. Nutanix is all about uncompromising simplicity. Nutanix will provide automation scripts to ease the process of deploying your VMs. Expect future developments in this area (and others) to make the integration and mutual support even tighter.

This great partnership brings together the best in the VDI world: Citrix XD/XA and the Nutanix platform. You can’t get a better VDI stack anywhere else.

You can read the Business Wire press release here, and the Nutanix press release here.

Nutanix Acropolis 101: Creating VMs

Now that Nutanix Acropolis is shipping with NOS 4.1.3, I wanted to cover a few basics in a series of blog posts. Most of you won’t be familiar with Acropolis, which is based on KVM. If you’ve used KVM in the past, you will know how difficult it can be. Acropolis removes much of the complexity and headache. So for my first installment, I wanted to do something very basic: Upload an ISO to the Nutanix cluster which I could use to image a VM, then create a VM and install the OS from the ISO.

Please take note that the Acropolis road map is quite detailed with many major enhancements in both terms of features and ease of use. So in a few months this procedure will probably change, particularly around ISO management. But 4.1.3 is shipping today, so here’s what you need to do. This assumes you have a running  Nutanix cluster imaged with Acropolis/KVM.

1. From your Windows machine launch WinSCP. Enter the hostname/IP of your Acropolis cluster, change the port to 2222, then use a username of ‘admin’ and your cluster password. WinSCP should then connect to NDFS.

2. Once WinSCP connects, in the right pane you will see a list of containers. If no containers exist, then you have a brand new cluster and need to go into PRISM and create a storage pool and container. Refreshing WinSCP may not reveal the new container(s), so you may need to reconnect to see them. I went into my first container and created a directory called “ISO”.

3. Next, in the left pane of WinSCP navigate to your ISO(s) and drag them into the right pane. Wait for the upload process to complete.

Note: In NOS 4.5 we will be adding a PRISM ISO upload option, so you won’t need to resort to WinSCP for uploading your ISOs. There’s also some cool feature in the future around ISO libraries that is in the works.

4. Login into PRISM (the Nutanix GUI not the NSA spy tool). From the left pull-down menu select “VM”.

2015-07-14_9-04-48

5.  From the left-side menu, select Create VM:

2015-07-14_9-09-38

6. Next up we need to define some VM parameters, such as memory and CPU. Fill in the form as appropriate for your VM.

2015-07-14_9-14-04

7. Next, click on New Disk. The dialog box below opens up. Assuming you’ve already created a container, just enter the size of the disk in GB. All disks are thin provisioned, so no need to select various format types.

2015-07-14_9-16-09 8. After the disk is created, we now need to add a NIC. If this is the first VM you have created, and haven’t yet defined any networks, we need to define a network to attach the VM to. You can of course have different networks, each associated with a different VLAN.  Click on “New NIC”, then you will see the box below.

2015-07-14_12-37-28

Because we have no networks, click on “Add Network”. Add the relevant VLAN ID and close the dialog box. Note, in NOS 4.5 you will be able to define network names, so you won’t have to rely on remembering long UUIDs.

9. Now, if you followed my article to inject the VirtIO drivers into your Windows ISO, then configure the CD-ROM to mount your ISO image from the NDFS datastore. If you have a virgin Windows ISO image and didn’t inject the drivers, then you can mount a second CD-ROM to the VM. In this second CD-ROM mount your VirtIO ISO image.

10. Power on the VM, and wait for Windows to boot. When you get to the “Where do you want to install Windows?” screen you have two option. First, if you created your custom Windows ISO then your boot disk should be listed and you can proceed as normal. If you are relying on the second CD-ROM, then click on Load Driver and browse to the vioscsi driver for the appropriate operating system. Your boot disk should now appear.

2015-07-31_12-33-55

11. Proceed with the Windows installation as normal. Once Windows is fully installed, login as administrator.

12. Open the Device Manager, and you will see a NIC under Other Devices with a yellow exclamation point. Right click and update driver software. On the VirtIO CD navigate to the NetKVM folder and appropriate OS. You NIC will now be detected.

2015-07-31_12-49-17

13. Congratulations! You now have a fully functional Acropolis Windows VM. Unlike other hypervisors, you don’t need to install any additional drivers..just SCSI and NIC. Keyboard, video and mouse are all native and should work as expected.

Nutanix NOS 4.1.4 Features

If you are Nutanix customer, you know that we release new version of our NOS platform on a very frequent basis. Release timing varies, but every 2-3 months you will see releases pop up. Some are major with a boatload of new features, and some are more bug fixes with a few minor features. I’m proud to announce that NOS 4.1.4 is now shipping! This is a minor update, but does have the following features: In NOS 4.1.x metro availability is synchronous replication between two sites, with no more 5ms latency between sites. NOS 4.1.4 brings some enhancements to metro availability:

  • Ability to take snapshots of a metro protection domain
  • Snapshot creation is driven from primary and performed on both primary and secondary
  • Only protection domain metadata replication is performed to complete the snapshot (minimal data transfer)
  • Interoperability with conventional async tertiary site.
  • User can create a schedule to replicate to async site from GUI
  • Metro configuration is a starting point for 3-site DR, with tertiary replication as an add-on

2015-07-20_13-11-34 Over the last year Nutanix has released a number of new models, to satisfy certain requirements such as compute heavy, cold storage IOPS heavy, all SSD (AFA), etc. We don’t stand still, and constantly listen to customers. So with NOS 4.1.4 will debut support for the Nutanix NX-1065s.

  • Replacement/Upgrade from NX-1020
  • Single CPU Socket (E-2630v2 or E5-2680v2)
  • Ivy Bridge CPU
  • 3.5″ 2TB, 4TB, 6TB drives
  • SSDs can be 480GB, 800GB or 1.2TB
  • Supports self-encrypting drive
  • Up to 256GB DDR3 RAM
  • 2x 10Gb NICs (or 2x 1Gbps)
  • SATADOM upgraded to 6Gbps

2015-07-20_13-58-59-aThere is also an enhance to our Acropolis hypervisor.  When an Acropolis host enters maintenance mode, VMs are moved to a temporary host. After the host exits maintenance mode, the VMs are automatically returned to the original host, eliminating the need to manually move them. Restore VM Locality also occurs when a failed node is restored on a cluster that was configured with Best Effort High Availability (HA).

This version also includes a number of security updates, to address several CVEs, such as TLS issues, DoS, and memory corruption.

NOS 4.1.3 and later support the NX-6035c platform mixed with other blocks in a cluster running the Acropolis, Hyper-V, and ESXi hypervisors.

Nutanix Engineering has significantly improved the performance of the disk firmware upgrade process, so you might observe better results when upgrading

And there you have it! Enhanced Metro availability, a new low-end block, enhancements to Acropolis and other new features. You can download 4.1.4 directly from the support portal. Not to far around the corner is a MAJOR NOS upgrade, with a list as long as my arm of new features. I won’t spill the beans, but stay tuned for some really cool enhancements. Also expect another minor release in August, with yet more features. And for those of you wanting full ‘legacy’ Microsoft clusters on Nutanix, stay tuned for good news on that front.
