Nutanix Releases NOS 4.1.1

I am very pleased to announce the latest release of the Nutanix Operating System, NOS 4.1.1, is generally available today. Download your copy today! This release offers rich enterprise capabilities to meet the needs of the most demanding applications and critical infrastructure requirements in the datacenter.

Here’s a summary of what’s new in this release.

  • Metro Availability: Nutanix Metro Availability provides continuous data availability for business-critical applications during planned maintenance or unplanned disasters that affect entire sites. Nutanix is the only hyper-converged infrastructure vendor to deliver continuous data protection across multiple datacenters. You can read more about Metro Availability here and here.
  • Cloud Connect: Nutanix Cloud Connect seamlessly integrates public cloud services, such as Amazon Web Services (AWS), with Nutanix-powered private cloud environments. It allows Nutanix customers to combine private and public cloud technology into their long-term infrastructure strategy without requiring third-party software or hard to maintain plug-ins. Read more about Cloud Connect here and here.
  • Encryption Support: Nutanix now provides strong data protection by encrypting user and application data to a level of FIPS 140-2 Level 2 compliance. Data at rest encryption is delivered through self-encrypting drives (SED) that are factory-installed in the Nutanix hyper-converged appliance. Find out more here.
  • Simplified Hypervisor Upgrade: Nutanix radically simplifies the process of upgrading the hypervisor in a Nutanix cluster with this new feature. This release will support upgrade of VMware ESXi and Microsoft Hyper-V, with KVM support coming soon. You can read about it here.
  • Security/STIG Enhancements: Nutanix has developed its own comprehensive security technical implementation guides (STIGs) to speed up the accreditation process for DIACAP/DIARMF, which is typically slow and manual. A process that typically takes nine to twelve months can now be accomplished in minutes. Over 500 embedded configuration changes were made to the system for compliance purposes. Major kudos to the security and development teams. Learn more here.
  • Prism Central Scalability: You can now manage up to 100 Nutanix clusters and 10,000 VMs. Prism Central now also supports Hyper-V.
  • Microsoft SCOM Pack: While not part of NOS, coinciding with the 4.1.1 release Nutanix has a Microsoft SCOM pack that monitors both Nutanix hardware and software. Great for Microsoft-centric shops.
  • XenDesktop Plug-In:  Again, while separate from NOS, Nutanix is unique in the industry by releasing a XenDesktop plug-in which enables you to configure per-VM SLAs. This is all configured with a few simple clicks from the XenDesktop Studio.

As part of the ongoing security hardening of NOS, 4.1.1 also addresses several attack vectors for NTP. Nutanix recommends upgrading to 4.1.1 to address these security issues. Certificate management in PRISM has also had a few improvements as well. For a deep dive on additional security information, check out this blog post by Nutanix’s Eric Hammersley. After seeing all the focus around securing our product automating the STIG process, you will agree with me that this is really industry leading.

For a “point” release of NOS, they’ve packed in A LOT of new features plus broader ecosystem support highlighted by the SCOM and XenDesktop add-ons. If you think these features are great, just wait to see what’s in our next point release.
