We are building a new platform to migrate two merging companies and will be moving data from both companies it. We have been using Dell Compellent as our SAN for many years and have recently had conversations with Tegile as well. We have a Cisco UCS blade chassis with 8 B200 blades and are running ESX 5.5. We also have a few other physical servers that have a mix of SAN volumes attached via FC as well as physical servers with local storage.
Coming into the fold along with the merger is a 400 seat Citrix farm. We are currently undecided if we will continue with Citrix (it is an older version and needs upgrading), but we also maybe be in favor of replacing those WinTerm machines with desktop computers and just publishing the applications.
But my main reason for the question is to get some feedback on Tegile itself. They are proposing their model 2300 with a shelf of drives to give the 80 TB that we need. An additional 2 TB of SSD storage they say will handle our current environment and their claims of deduplication and compression will allow this.
We have a comfort level with Dell Compellent and think very highly of their CoPilot support team. Dell's solution of our project involves a Tier 0 with 24 TB of SSD Storage and 80 TB of Tier 3 storage along with two SC8000 controllers to head the unit up. The prices are about the same.
Tegile seems like cool technology, but the downside we hear is 1. Their claims of dedupe and compression are misrepresented by their graphical metrics (i.e., your compression rates are not accurate). 2. Their support leaves much to be desired.
The downside of Dell is that their Tiering structure is not as dynamic and that Data Progression rates with "hot" data may not be as fast.
As I mentioned, both systems cost about the same.
Can anyone speak to the pros and cons to Tegile vs. Compellent and what sort of factors we should consider in making this decision on which choice to go with? I am personally having a tough time deciding between the two, but need to make a choice fairly soon. Thanks for the input.
