Dear Colleague,  I am the CEO of a small tech services company. I need a comparison between Unity 400 and PowerStore 1200. Which solution do you prefer and why?Thanks

The Unity 400 is a rather old, a much less powerfull solution and at its best holds ssd flashdrives if at all. Currently you have the Unity 8xx model, which has more CPU punch and therefore maxes out less fast on CPU utilisation. What this means is that you can add more shelves and disks and workloads to it before you hit the roof.   The powerstore 1200 is an nvme storage, is 60% more powerfull (compared to FC/SCSI-SSD on Unity) in our case, and has higher datareduction rates. If the unity reaches out to a datareduction rate of 1.5 or 2, the Powerstore T1200 is capable of 3 to 3.5 datareduction, probably due to half its blocksize. The price of the device is pretty much dependant on the price of its media, and therefore the Powerstore T1200 is the absolute winner. . Another aspect is that the Powerstore can be used to build a cluster of arrays compared to the sync/asynch replication only feature of the Unity series, rendering the mirrored volumes unuseable unless one fails over to it, like in a disaster recovery scenario. . The Powerstore also allows true A/A volumes on both sides . What this means is that one can build stretched vSphere clusters and the loss of your array in one site will still allow writing to the alternate protected disk, transparently ! You can have site local writes to your volumes and remain in sync without a need to cross site write. . There is not much of a reason to settle for the Unity anymore, though some still prefer the Unity for NAS compared to Powerstore, but honestly speaking I won't recommend to use any of both for that purpose unless for limitted useage. Unity allocates RAM ressources dynamically when used for FC/SCSI AND NAS , whereas the Powerstore is initialized in a kind of split off of RAM ressources between NAS/FC SCSI at installation time. The ressource allocation is fixed and can't be altered lateron.  Thats a hard call. So I'd favour the Unity only if you use it for low/moderate NAS needs in combination with FC/SCSI or block data and you don't have the budget nor the size to use a NAS optimised array on top.

Hello Yasin,  The best solution depends upon your host environment. In general, PowerStore is more powerful than Unity but Unity is also a very good Storage solution.

The price of the solution is reasonable compared to others, such as Dell EMC.
