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.

NetApp AFF A-Series All Flash Arrays

We us our AFF to support all applications that have a response time imperative or are IO intensive such as databases, email, VMware VMs and applications that have users at a keyboard needing a responsive interaction. It is also where we put all data that must be encrypted at rest such as HIPAA data.
It is of no value to data that is generally archived, little used or has low IO requirements. These would include scanned images, videos, IP Camera storage and most CIFS and NFS file based storage. For these types of applications SATA is still a better choice.

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

NetApp AFF A-Series All Flash Arrays

  • Supports CIFS, NFS, ISCSI and FC protocols. Not all flash products out in the market today support all protocols and this makes it harder for small - mid scale organizations who cannot afford multiple million dollar storage platforms.
  • Handles workloads really well. We have VDI, SQL DB, Production workloads running on it all at the same time and the array doesn't choke on latency or IOPS.
  • CDOT has come a long way and with the newer versions of CDOT, the data reduction and compression makes way for a lot more usable storage than what you pay for in RAW.

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.

  • The GUI of Ontap is in constant flux. Every time there is an upgrade it appears to be completely redesigned. Some stability in its design would be nice
  • As new or improved technologies addressing compression, compaction and deduplication occur within upgrades it would be nice if preexisting data could benefit from it by background processes looking for opportunities to apply savings to data in place.
  • It is not simple to see when data from the AFF is being access inefficiently through the cluster interconnect. Because data moves sometimes access to the data remains with the nodes that originally owned them. I would like to be able to easily identify these instances so that I can take corrective action.

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.

We looked at Pure, Nimble, XtremIO and NetApp. Although all the arrays did really well, the ability to support all protocols sets NetApp apart. Each vendor had its own pluses and minuses and we bought the array that best suited our business needs and budget.

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.

  • Epic, our EMR providor, has very aggressive guidelines for performance. The Netapp AFF meets those guidlines easily eben in a mixed workload environment. This has helped us meet our business objectives by not having to diversify our storage platforms or vendors.
  • Multi-protocol support (block (ISCSI/FiberChannel) or File (NFS/CIFS)) Allows us to use the Netapp systems to solve all storage requirements regardless of the system needing storage
  • Clustered technologies along with non-disruptive movement of data between nodes on the cluster make hardware refreshes simple and allows the business to keep running without interruption even during massive data moves.
