It could help to add more detail on the networking side. Better integration with RecoveryPoint would be helpful. Support has a lot more access and visibility to things that are happening. If we have more visibility it would help for troubleshooting purposes and allow faster resolutions to issues.

The hardware itself is great, apart from few issues I had with it recognising disks from the officially supported lists. Another disadvantage is that you cannot really mix and match disks, at least in my experience. The support can be a bit nicer, however, once you get to an escalation point, things start getting better and my issue was resolved quickly. Performance is stellar, ease of use is great - very intuitive. All in all - very good product, marginally let down by not great support at the first line.

Pros

Dell EMC Unity

  • Very reliable arrays with a notification system when a disk fails
  • Simple disk provisioning and mapping
  • Easy to upgrade the firmware
  • Fast access with a relatively cheap storage combination of flash and SATA drives
  • integrates with Vmware vcenter

  • Data processing and IO. The Storwize devices are very resilient in how they process data and do not have a drop in IO when errors occur (common errors such as disk failures and lost paths).
  • Storage efficiency management. We are able to use multiple efficiency techniques such as thin provisioning and data reduction to reduce our budget footprint.
  • Easy to use interfaces. Creating a volume and mapping to a host has proven to be a very easy process and makes onboarding less stressful for our team.

Cons

Dell EMC Unity

  • Alerting: receiving an alert when an issue occurs. That is good to know. However, if the alert is cleared, or somehow no longer in alarm, no email is received. At times I will receive the email alert on weekends, not knowing if the issue is resolved or not until Monday when I can access the unit. I have learned in most instances, the alert is a false alarm, which could be a problem.
  • The alerting itself is sometimes not clear. For example, it tells me the link is down, we reset the connection, the link is still down, a tech was dispatched, he troubleshot, and finally the alarm cleared. This incident took almost a week. It went back into alarm after he left, then suddenly it cleared on its own.

  • As a business partner looking to provide services to keep the uptime of the Storwize, I would like to have the capability to pull reports from IBM Storage Insights to assist my clients in managing their system through it's lifecycle.
  • More knowledge out there for partners to best integrate IBM Storwize with IBM Power i. This seems to be lacking in communication from IBM.

Dell EMC's support for the Unity array is normally quite good. However, when there are issues with the reporting and statistics, they often are not responsive.

Alternatives Considered

Dell EMC Unity

We selected the Dell EMC Unity after looking at several other vendor solutions. We were budget conscious and wanted to select a device which would bring known quantities to the table. We were looking for devices which could support flash drives as the read cache for frequently used files but also needed a device to fit within our sizing and budget.

IBM Storwize is a part of a family that is complemented by the products listed. In many negotiations, involving storage is our workhorse to ensure several businesses thanks to its balanced cost and all the benefits that we offer.

Return on Investment

Dell EMC Unity

  • ROI on VxBlock is not so good since RCM updates cost a lot.
  • ROI on Unity by itself is good, however.

  • I would like to highlight the most positive aspect I have seen in the products of the IBM Storwize family, and it is the ROI that we can choose when we offer real-time compression with the IBM V7000 family. In truth, this feature is excellent, and we have seen how customers save storage resources, rack space, power and management.
