IBM FlashSystem Review

SRM, Highly Scalable, multivendor backend storage support, Easy Migration Path

What is our primary use case?

In a bank.

How has it helped my organization?

- Migration efforts - Site recovery using SRM - Highly scalable while backend storage can be of many vendors - Ideal solution if you have a mixed intel/power infrastructure Ease of use

What is most valuable?

  • Migration effort
  • Site recovery plan.

What needs improvement?

- CLI though intuitive, no other API available - Lacks scheduling or a cron - Has no built in short term performance graphs - IBM TPC overexceeds the montoring needs, had to fall back on Stor2RRd - Support response times are bad -

What do I think about the stability of the solution?

Node conditions in specific workload conditions might trigger a node reset.

What do I think about the scalability of the solution?

- Multivendor support for backend storage - Clustering and adding in another IO--group - supports many shelves, large disks, several clusters

How are customer service and technical support?

- Bad response times

Which solution did I use previously and why did I switch?

IBM SVC -> HP 3PAR -> Storwize v7000f

How was the initial setup?

- Easy and straighforward

What about the implementation team?

- selfserviced

What was our ROI?

Biggest return is the easy migration/upgrade path as well as the scalability options - IBM added in compression and deduplication in its portfolio, as well as Garbage collection and space reclamation.

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

- setup cost is cheap as you can do it yourself - IBM SVC licensing on non IBM back-end storage used to cost a lot in terms of licenses per shelf or even per TB. The equipment on itself is relatively cheap. Watch out for license costs !

Which other solutions did I evaluate?

- HPE 3PAR StoreServe - EMC Unity
