An affordable iSCSI/NFS/NAS box for your house

A co-worker of mine, Mark, turned me on to this company called QNAP. They make a really dizzying array of SOHO and small/medium business "NetApp" like NAS devices. These little babies support a wide range of protocols including iSCSI, NFS, CIFS, ftp, etc. It's really amazing what these critters can...

RIP Fibre Channel Drives – Hello storage tiering

SQL 2008 Security and vCenter 4

This past weekend I worked on automating our SQL installs and scripting security lockdowns. During that effort I found the new policy evaluation tool in SQL 2008. This built-in tool allows you to run specific checks against your SQL 2008 installation to report on best practices. During my evaluation everything...

Scripting SQL Server Firewall Rules

On servers that are running Windows server 2008 or later, you can take advantage of the built-in two-way firewall. SQL server firewall rules can be pretty easily created through the GUI, but it can be a bit tedious. So I wrote a little batch file that asks you for an IP...
