Quantum DXi Series vs. PowerProtect DD Series

As a backend disk solution for NetBackup it works perfectly, and is easy to install and get up and running.

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.

• Backup and replication for VMs are going well with our Quantum DXi solution.
• Deduplication level is great, the GUI informative and well placed.
• Differential backup replicated properly and fast to DR site.

Incentivized

• 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.

• We had some expansion issues with the DXi 8500s and needed to implement a secondary DXi6902 system to allow for the expansion required.

Incentivized

• Depending on the model of Data Domain, there is a limit to the number of NFS/SMB threads that can run concurrently. When this limit is reached, the system is slow to respond to client requests.
• Data Domain support is very slow to turn out new features and bug fixes in their code.
• OS upgrades are very slow and disruptive.

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.

The actual support personnel and the support provided is very good, and they are typically very responsive to any request that come in. We have never had a bad support experience. All support has been based in America and have always been able to resolve any issues or problems that have come up. the automated call home feature works well.

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.

Cost effective and performance were the main reasons why we took Quantum DXi. Software and cloud solution may be better for us right now. We are going to find some new ways to do backup and DR properly.

We already had Avamar in place, and since we have a good ecosystem of Dell Solution suite and wanted to evaluate PowerProtect DD also from that perspective, hence we thought of going ahead with it. We knew the limitations with Avamar and PowerProtect DD were right there from that side of the business.

• Storage Target for data that can be Deduped
• Using accent to do inline dedupe is great
• Works well with netbackup accelerator and netbackup

Incentivized

• Positive: The high compression (58.0x) and data reduction (98.3%) have allowed us to optimize the storage for efficient usage.
• Negative: even after adding capacity, we are running out of space. Adding capacity adds to the overall TCO (e.g. lease cost).
