Likelihood to Recommend
Dell Compellent has a decent portfolio of products for varying sizes of business. Their licensing model is suited for those not wanting total a la carte fare, and administration is intuitive as compared to other storage arrays. This combined with Co-Pilot support gives Dell a good presence in a vast number of scenarios where networked storage is required over a DAS solution. It's only fallback is its own NAS solution, which itself may be better suited to smaller environments

If you are looking for a solid storage array that needs to give you continuous uptime, then VNX is a great solution.

Pros
  • Block level RAID with data tiered based on how often those blocks are read or written.
  • You can mix and match different ways of accessing the SAN, FC or ISCSI.
  • They offer the ability to mix and match drive speeds and sizes within racks. This provides for larger, slower drives to store old data, while providing fast SSD storage for data that is constantly in use.

  • Auto- tiering, for faster access on blocks used most frequently
  • Has both NAS and SAN ( unified system)
  • Scale up ability
  • Optimal for VMware
  • Integrates with vCenter
  • Easy monitoring and useful dashboards
  • Relatively easy configure and management interface with safe delete

Cons
  • Reliability. We had several times where VMFS luns would become corrupted and we'd have to move all VM's off to other storage
  • Performance. 1g iSCSI performance was abysmal (although the unit we used was an older device)
  • Management and Monitoring. Both management and monitoring are pretty primitive. We were never able to integrate monitoring into Nagios.

  • The UI is very clunky and uses Java, which I am not a big fan of.
  • It is difficult to see performance metrics or utilization. Tegile or Nimble provide a superior window into your performance and IOPS on LUNs and VMs.

Support Rating
This is not solely based on the support engineers themselves but more so that the logging and gotcha's that their array has. There have been multiple times where logs are pulled, but the folder is not large enough, and it crashes the array. Other times there are certain aspects that support either does not know of or isn't knowledgable about how to look at particular issues that could be causing problems.

Alternatives Considered
I have used Dell EMC Unity XT and I will say that the SC Series is better in the areas of the scalability is excellent. If I need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself. In addition, I like the way it integrates with our environment. These features help us use multiple soft applications. They give us an advantage versus traditional storage resources.

  • Dell EMC Unity is the improved version of EMC VNX. It has all the features in VNX with better performance.
  • NetApp all flash is faster and more expensive. It performs better with Citrix systems and VDI solutions.
  • HP MSA storage system is less performant and less expensive. It works better for file and CCTV data storage.

Return on Investment
  • This storage array is a middle-range array that brings speed with peace of mind due to the stability.
  • The uptime has helped us with making sure the hosts and servers that connect to this array have as much uptime as possible.
  • The negative still has to be that these arrays can't seem to handle quick/high I/O usage.

  • Due to its stability, it is very rare to have downtime—meaning business operations are not interrupted from an infrastructure level.
  • Support and maintenance can be expensive.
