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.

PowerProtect DD (formerly Dell EMC Data Domain)

When used as a backup target PowerProtect DD models offer incredible density and can efficiently replicate to another cloud-based or offsite unit. Most complaints about these have been addressed in software over the years and they are now a intuitive and easily managed backup system. You are not buying a Swiss army knife, you are getting a machine designed for a purpose, use it for that and you will not be disappointed. While they have the ability to serve as a CIFS server, they are not a filer and lack many of the features inherent to filers and are a poor substitute.

Pros

  • Fast access with a relatively cheap storage combination of flash and SATA drives
  • integrates with Vmware vcenter

PowerProtect DD (formerly Dell EMC Data Domain)

  • It writes backups quickly. DDBoost add-on is very useful as well for improving backup speeds.
  • DD is very efficient in its use of capacity. It dedupes and compresses very well.
  • It spans to large capacity amounts.

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.

  • It can be expensive to implement, especially when used in conjunction with other applications/hardware such as Avamar.
  • The TCO can be high, especially when it needs its storage expanded.
  • Recovery speeds can be slow (compared to other solutions) for when recovery is time sensitive.

DD has performed flawlessly for almost 10 years as our backup/recovery storage with offsite replication. Given its track record and great support from EMC, we're unlikely to look elsewhere any time soon.

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.

Customer support has had some ups and downs here. We've had several issues with EMC support before and during the acquisition by Dell, but in the last 18 months support has been top notch. Quick and knowledgeable help is but a chat away, or they will call you back so you don't have to wait on hold. The team supporting us is responsive and is quick to assist with any request or issue.

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 selected Data Domain due to its integration with our backup software. The Data Domain works well for what we need it to do.

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.

PowerProtect DD (formerly Dell EMC Data Domain)

  • We were able to immediately discontinue our remote tape storage and TBU maintenance.
  • Reduced backup footprint in the data center.
  • It is costly to expand so buy it with a purpose.
