Easy to set up with great deduplication and easy expansion capabilities
Pros and Cons
- "The solution is stable."
- "One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly."
What is our primary use case?
What is most valuable?
There are a few great features. Obviously, deduplication is a big one. There are the catalyst stores that we are using. It's a feature that does what we need it to do. We've been using the 5100 for quite some time with a lot of success and no issues. However, we were looking, at first, at expanding, however, we couldn't expand them anymore as they were at end of life. Now we are looking at the new generation, the latest, 5260.
It is easy to set up the product.
The solution is stable.
You can easily scale the solution.
What needs improvement?
I haven't come across any missing features.
One item I wanted to see is SSD drives as a cache. Data is taken in by the subsystem on SSD drives and as later on offloaded to spinning media. That was a feature that you could already see in primary storage, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly.
For how long have I used the solution?
I, myself, worked for HPE for 34 years. Now, I'm working as an independent consultant. I'm working at a pharmaceutical company and they've been using it for four years.

Learn what your peers think about HPE StoreOnce. Get advice and tips from experienced pros sharing their opinions. Updated: June 2025.
860,632 professionals have used our research since 2012.
What do I think about the stability of the solution?
It is an absolutely stable solution. We haven't had any issues. There are no bugs or glitches. It doesn't crash or freeze. it's reliable.
What do I think about the scalability of the solution?
The solution is definitely scalable, to the extent that we need it. For our purposes, it is definitely scalable enough. It's modular enough. You can add, with the 5260, 192 terabytes of raw capacity that you can extend one shelf at a time.
How are customer service and support?
Technical support is helpful, however, an advantage that I have is that I know the company inside out. I still have contact with my former colleagues there. They do their job. They are helpful and responsive.
How was the initial setup?
The solution is easy to set up. It's not complex or difficult. I'd rate it nine out of ten in terms of ease of implementation.
What's my experience with pricing, setup cost, and licensing?
I'm not into financials. I'm a technical guy. I just help with planning and designing a solution, and then others decide on pricing and configuration. I'm working as an external consultant, therefore, I don't have any decision-making there.
Which other solutions did I evaluate?
I don't have any practical experience with many other solutions. Coming out of HPE, going to work as an independent consultant in a company that is using a lot of HPE products, I'm obviously quite satisfied that they are using StoreOnce, and they will keep on using it.
What other advice do I have?
In terms of the version we are using, we have the StoreOnce 5100 and now we're looking at the StoreOnce 5260.
I'd recommend the solution to others. It has the features that we require and the features that, are required by a lot of companies that have a lot of data today. It's all about data. Data requirements are booming in the primary storage market and storage subsystems. Obviously, to be protected, you need to back up the data. And there, it does what it needs to do. There are petabytes of user data that you can store on a terabyte type back up to the disk subsystem.
That said, if you go to medium-sized companies or small-sized companies, probably there will be cheaper and smaller-scale options. For instance, the StoreOnce that we are using, are long connected, so they are accessed through the network, however, they're also connected through a SUMP, so a storage area network. That is something that you find mostly in the bigger companies that have the financial means to buy these types of subsystems. It would be depending on size and requirements. For bigger organizations, therefore, I would definitely advise they go for this product.
I would rate the product nine out of ten.

Head of cloud service. at a comms service provider with 51-200 employees
Very reliable, good deduplication and compression ratio, and supports the HPE Catalyst protocol
Pros and Cons
- "Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access."
- "When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."
What is our primary use case?
We use it for our virtual workload back up. We are also a service provider, and we provide backup assistance to clients. We use StoreOnce for that backup too.

There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later.
For how long have I used the solution?
I have been using this solution for a month. We bought it very recently.
What do I think about the stability of the solution?
It is a very reliable solution.
What do I think about the scalability of the solution?
You can't increase the hard disk size. We bought two units. We have one unit connected to another unit. We have got ample capacity so far, and there is no need to increase it.
Currently, we have around 15 users. We have bought it for the backup of our customers. When it comes to customers, there are hundreds of customers.
How are customer service and technical support?
They have been very responsive.
How was the initial setup?
It was very straightforward. We knew the requirements, so we segmented it as required.
What's my experience with pricing, setup cost, and licensing?
We have got a perpetual license, and we have access to all the features.
If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed.
Which other solutions did I evaluate?
We evaluated EMC Data Domain. We decided to go with StoreOnce because it was more cost-effective and suitable for our budget. Its interface was also easy to use.
What other advice do I have?
I would recommend this solution. For higher data capacity, we can have around 90 terabytes, and roughly, we can take 75 terabytes of effective capacity. It can do deduplication. As per the papers, it will do 20:1, which may not be realistic, but we have seen 8:1 kind of deduplication. Even if it was 2:1, it will be 140. So, deduplication gives a massive capacity.
I would rate HPE StoreOnce a nine out of ten. It has been very good so far.
Which deployment model are you using for this solution?
