EMC Celerra VSAFebruary 18, 2009
Virtual Storage Appliances (VSA) are really picking-up these days. Even the legacy hardware vendors are getting into the fray. They’re great in the lab and – assuming tailored performance – can fit some really interesting “embedded” applications.
If you haven’t had a chance to look at the EMC Celerra VSA then click over to Chad Sakac’s VirtualGeek Blog and have a look at his series on configuration and testing. If you have time, check out some of Chad’s more visionary stuff while your there – he has some good information on what’s to come in the next few months from EMC and VMware…
For the Celerra VSA, look at these two links

If you’re new to iSCSI and VMware, check-out Chad’s post on iSCSI with VMware – it will get you on the right track.
- If you’re using “homebrew” or “white box” equipment and do not have SCSI attached local storage, do not expect ANY level of performance – especially with Nvidia-based controllers. Try picking-up a cheap LSI or Adaptec storage controller for your lab tests.
- The Celerra VSA is for non-production environments only (lab, testing, etc.)
- The Celerra VSA does not support SMP – so faster cores are a benefit.
- The Celerra VSA accomplishes in one node (and processor) what multiple nodes and processors do in a real (hardware) Celerra. That said, expect appropriate performance degredation.
