What is most valuable?
The most valuable feature would be the high deduplication ratios, capable of 20 or more to 1 dedup ratio in a real-world backup environment. It seems to work very good for long retention times, even if there is little use, but sometimes you have to do it due to legal reasons, and that is where it shines.
How has it helped my organization?
In my previous organization, it removed the need for manual tape swapping. Hence, it removed the need for actual tape changers to be at 50 separate remote sites, leading to huge savings for the company.
Also, offsite tape storage is replaced by replication to a different/central site/device such as StoreOnce B6200/B6500 or even some lower-end one, such as 4900.
What needs improvement?
I would like to see them add the ability to turn on/turn off global deduplication and etc.
Currently, only VTL-level deduplication is supported properly, while there seems to be some part of global deduplication working. However, in some rare cases, I saw data being removed on untouched VTL while you were deleting some particular cartridge within a separate VTL. It has probably been fixed by the most recent StoreOnce OS upgrades.
For how long have I used the solution?
I have been using it for 4+ years.
What was my experience with deployment of the solution?
I have not encountered any deployment issues.
What do I think about the stability of the solution?
Some models are shipped with one power supply by default, even when redundant PSUs are supported in pairs; be aware of that.
What do I think about the scalability of the solution?
As long as the architecture was done correctly, I did not encounter any scalability issues. If an entry-level StoreOnce device is placed on a “soon to grow“ site, that is a planning mistake, not a scalability issue.
How are customer service and technical support?
Customer service is great. Technical Support
Technical support is great.
Which solution did I use previously and why did I switch?
We switched because of company policy, the tapes aged, etc.
How was the initial setup?
Initial setup was straightforward.
What about the implementation team?
I was within support team, which did implement as well as support the solution.
What was our ROI?
Huge. Simply eliminating the need for tape changers returned the cost of the hardware within less than half a year.
What's my experience with pricing, setup cost, and licensing?
Get an expert who knows the products, so you can get the best prices possible for both DP and StoreOnce. Because there are some things that can work for the same solution in different ways, hence they are differently licensed as well as priced.
What other advice do I have?
Make sure architecture is planning properly, e.g., centralised or decentralised HPE DP Cell Managers give you some quite different options and etc.
Which version of this solution are you currently using?
2620, 2700, 4900, B6200, B6500
