Disk Formatting Best Practices • Use the default block size, or allocation unit size, unless a particular application specifies an alternate size. Microsoft Exchange should be on volumes formatted with a block size of 4096 bytes. • Partitions should be created starting at sector 128 to align the offset to 64KB using Diskpar or Diskpart. -

The LeftHand Networks SAN is designed to work on your existing Ethernet infrastructure. Segmenting the storage network from your corporate network is recommended, and boosts overall performance of the solution. For performance testing, the SAN network was isolated to a single broadcast domain (subnet) and had dedicated NICs for the storage traffic. - Page 9 Microsoft Exchange Jetstress The Jetstress tool allows administrators to verify the performance and stability of the disk subsystem before putting their Exchange server into a production environment. It reports back to the administrator with an html document that contains results and a PASS or FAIL for the overall test. A PASS or FAIL is strictly based on specific test results not exceeding Microsoft specified limits.
