Compellent Review

You can create volumes and easily assign them to VMware clusters, increasing their size

How has it helped my organization?

There is no need to archive data and/or move data from expensive storage since the device does that itself depending on the use of the data. This is the data that you moved to the slower disks.

What is most valuable?

  1. Easy management of volumes: You can create volumes and easily assign them to VMware clusters, increasing their size.
  2. Performance management: The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources.

What needs improvement?

Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage.

For how long have I used the solution?

Three to five years.

What do I think about the stability of the solution?

No issues.

What do I think about the scalability of the solution?

It is more difficult than others, since once you need to growth, you need to make sure what tier you will increase to in order to redistribute the data. It can take more time and planning, but is worth the effort.

How is customer service and technical support?

Excellent, Copilot (support for Compellent) is excellent.

Which solutions did we use previously?

Yes, we used to have EMC and Hitachi Storage. The growth of storage was limited and price/performance were not good.

How was the initial setup?

Initially, it can be difficult since you need to understand the tiering philosophy. It is very different to normal SAN deployments, but once you understand them, they are very straightforward.

What's my experience with pricing, setup cost, and licensing?

Take your time to meet with your representative and tell them your needs and listen careful to every recommendation. Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution.

Which other solutions did I evaluate?

Yes, IBM's and HP's tiering solutions, but there are too expensive and bulky.

What other advice do I have?

Document your needs, current storage, expansion, and timeframe for replays (snapshots). If you have backups or replications in place, make sure they work with Compellent Tiered Storage.
