We hope to unify all our solutions, so because our storage is HPE and all our services are HPE, we also need to use StoreOnce for our backup. It has good features.
System Analyst at Saudi Electricity Company
It is part of an initiative to unify our solutions with one vendor. I would like to see automatic restore.
What is most valuable?
How has it helped my organization?
Support is the main thing. If we have any issue, it’s easy for us to track or investigate it, because we don’t have different solutions from different vendors. This is the main benefit we are getting.
What needs improvement?
I would like to see automatic restore and monitoring tools like a dashboard.
For how long have I used the solution?
We started using it in 2015.

What do I think about the stability of the solution?
We have had some issues. We are working with HPE to solve all the issues. For example, when we try to restore, other solutions have automatic restore.
Currently, we need to do it manually and it takes a very long time. This is a critical issue, but we are working with HPE on it.
Also, the hardware is from HPE and the software is from another company that is part of HPE and this causes some problems. So, if we have any issue with the hardware, it’s solved quickly. But, if we have any issue with the software, for example, with the console, we need to reschedule the jobs or there is a delay in a job, we need to go back to that company through HPE. This takes time.
What do I think about the scalability of the solution?
Scalability is fine.
How are customer service and support?
We use technical support quite a bit and we are not so satisfied with them. I rate them 3/5.
What other advice do I have?
HPE introduced us to this solution.

IT Infrastructure Manager at Olympique Lyonnais Groupe
It integrates with our backup solution, Veeam. We use it to replicate all our site backups.
What is most valuable?
For us, we can save a lot on storage costs for doing backups. It integrates seamlessly with our backup solution, which is a third-party solution, not from HPE. We use Veeam; and StoreOnce works with them.
How has it helped my organization?
It works great for backing up Windows. Backups are much quicker now. Previously, it took 15-16 hours every day. Now it takes 3-4 hours maximum.
Replication of our site using Virtual Storage Appliance is really easy. We did not have any backup solution for our site before. Now, we just have Virtual Storage Appliance running on site almost without any configuration. We use it to replicate all our site backups.
What needs improvement?
I would like to see a better integration with Active Directory to identify users. Currently, we need to create separate accounts, so we need to have separate passwords to log in for assurance. It's not a big issue, but it is an issue. We would like to be able to use existing Active Directory accounts to directly authenticate users.
There could always be better performance. There is a little bit to work on in this area.
For how long have I used the solution?
We’ve been using it for little more than a year.
What do I think about the stability of the solution?
It is stable. We hardly ever had an issues with it.
What do I think about the scalability of the solution?
When we started, it was already quite large, about 200 TBs. So far, we haven’t had any need to scale up.
How are customer service and technical support?
Technical support is quite efficient. We only had minor issues, but they were handled pretty quickly.
Which solution did I use previously and why did I switch?
We built an almost entirely new IT infrastructure for a new stadium that we built. The new infrastructure had a lot more than it had before; so we knew we had to have a better backup solution.
How was the initial setup?
The initial setup was relatively easy. We didn’t need to do a lot. They were already pretty well-packaged out of the box. Aside from the configuration and integration with the backup solution, we didn't have much to do.
Which other solutions did I evaluate?
We looked at EMC, IBM, NetApp, and some others which I cannot recall at the moment.
We are building an entirely new infrastructure. We chose HPE StoreOnce after considering the servers, the storage, and the backup all at the same time. HPE had a better global solution, especially in terms of the backup solution.
What other advice do I have?
Look into intuitive solutions for storage space. Deduplication is really efficient. You can do deduplication directly with Veeam, the backup software, side now. We save on network and bandwidth.
The most important criteria for us when selecting a vendor was the integration of the old backup solution in the previous stadium, and the need to save on storage space.

Chief Technology Officer at theCloud Limited
The most valuable features for us are the ease of use, the reliability, and the deduplication.
Pros and Cons
- "The most valuable features for us are the ease of use, the reliability, and the exceptional deduplication that we get across that data that we store on those devices."
- "We would like to see some improvements in the Veeam Backup & Replication integration. It's good, but it has a lot of room to improve. In particular around the inability to easily move data between StoreOnce appliances."
What is most valuable?
The most valuable features for us are the ease of use, the reliability, and the exceptional deduplication that we get across that data that we store on those devices.
We use it primarily for storage of backup data. We need to keep large numbers of historical backups and they typically repeat. It's a lot of data that is the same, but has to be kept for the purposes of historical reasons. You have to go back to points in time and storing the data on standard disks is wasteful and inefficient.
We needed a deduplication of parts. We've tried a number of different options and we settled on StoreOnce's being the most efficient and the fastest technology that met the price point that we were looking for.
How has it helped my organization?
In the service provider business, we are competing with a large number of other organizations and a lot of the time price is what matters to customers. We need to be competitive. We need to be able to provide a service at a price point that meets market expectation and this is a particular consideration in what we were looking for. The deduplication storage appliances and StoreOnce in particular does that by allowing us to provide lower price cloud storage for customer data
What needs improvement?
We would like to see some improvements in the Veeam Backup & Replication integration. It's good, but it has a lot of room to improve. In particular around the inability to easily move data between StoreOnce appliances. Also, there are some limitations around how it can be implemented for Cloud Connect repository storage. We currently have to use SMB Shares rather than proper Catalyst integration. It's an interesting scenario, because Veeam tell us that it's the way HPE's StoreOnce Catalyst integration works and of course, HPE are saying that it's Veeam who have to work with us on this. We are hoping that they will get together and come up with a good solution and vision, too.
For how long have I used the solution?
We have been using HPE StoreOnce appliances for just over two years now.
What do I think about the stability of the solution?
We've had failed disks but we've not lost any data and HPE's support has been very good. We did have some difficulty with the phone home functionality originally. Oddly enough, in one case, a firmware update fixed that for one of the devices. Overall, we found them to be very reliable.
How was the initial setup?
I think it's interesting. The first one we did, we paid for HPE to install it, so they went through the whole setup process and everything else. I suspect that's probably why they normally get you to pay for it, because we did it ourselves from the second one and it was fine. It's not simple. It's not the click and point; it's command line. It's more technical; it's not a simple process, not like their wizards that you get with most of their products.
What's my experience with pricing, setup cost, and licensing?
To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality; it was priced quite well in the market. We are looking for larger StoreOnce deployments for other requirements at the moment. Again, we are finding the price point quite attractive.
From that point of view, no problem at all. I'm just trying to think from a licensing point of view, they do seem to like charging for every little component. If you want to put a 10Gb adapter in there, there is a license charge for that. If you want to put in a fiber channel adapter, there is a license charge for that. On the whole, it hasn't been a limiting factor for us at all.
Which other solutions did I evaluate?
We looked at EMC Data Domain. We looked at Microsoft Storage Server on a number of different appliances, including an HPE option there. We found with Windows Storage Server, the performance wasn't there. It just didn't meet our requirements. We use Veeam backup and replication, and the integration that StoreOnce provides works really well. We have a very strong relationship with HPE and in the end they kind of swayed us.
What other advice do I have?
I wouldn't want to say it's perfect because there is room to improve, but for what we are using it for, we are finding it does the job really well.
From a data point of view, you've got to be confident that the data you're storing is going to be deduplicable. Otherwise, you're not going to get any savings. If you're storing prededuplicated data, highly compressed data, data that doesn't repeat, you just wasted money on expensive disks, because you're paying a premium for the benefit of the data to be deduplicated.
You obviously want to be sure that the data that you're putting there is going to compress very well. We knew that was the case, so it was a no-brainer for us. I think we got a bit more deduplication than we were expecting, which is always wonderful. It doesn't always happen that way.

It's cost effective, technologically advanced, and scalable.
What is most valuable?
It's cost effective, technologically advanced, and very scalable. It integrates with the rest of the HPE infrastructure, like 3PAR, for example.
How has it helped my organization?
From a business point of view, it enables us to pay closer attention to our caps and our competitive cost level.
Because it integrates with other HPE systems, it is easier for us to manage compared to the system we had before.
What needs improvement?
I would mostly want to see some technical improvements in some very specific areas. For example, a feature that is missing, compared to the competition, is the ability to globally duplicate all systems.
EMC Data Domain can deduplicate globally among all volumes, whereas HPE StoreOnce's deduplication is per single volume. Thus, it is a little less efficient, if you have several volumes.
What do I think about the stability of the solution?
So far, it looks quite stable.
What do I think about the scalability of the solution?
Scalability is very good.
How are customer service and technical support?
We get technical support from our partner and also from HPE personnel. The support is very good.
Which solution did I use previously and why did I switch?
The previous system reached its end of life and it was becoming obsolete. It was no longer performing enough for the company. Business is flowing, fortunately; so we needed a faster and more scalable solution. The switch to HPE StoreOnce was a planned investment.
How was the initial setup?
I would say the initial setup was straightforward, but I was not involved from an operational perspective. I am involved in that I am responsible for the teams; so I was involved in setting the objectives and I was informed of the key facts. I’m not the one who strokes the keyboard.
Which other solutions did I evaluate?
We actually work with HPE a lot, but also with Dell EMC. For now, we balance the distribution 50/50. There's some good in both vendors.
What other advice do I have?
My advice to colleagues is to deeply explore the features of StoreOnce because they have improved in the last year. StoreOnce is not the market leader. The market leader now is without any doubt EMC Data Domain. Try not to just look at the market numbers, but also at the technology of the product. Give StoreOnce a try. Try the product before deciding to buy it.
The most important criteria when we choose a vendor is the technology. We are very technically oriented, so first we compare products in terms of technological level. By technology, I mean features, performance, and integration with other vendor solutions.
We put cost effectiveness a little lower in our evaluation. Price is obvious, but it is not the main thing for us.
The partnership with the vendor is very important. The partner must have strong competence in what they are selling to us. It is obviously very important to have a skilled and certified partner that helps you implement the product. This restricts the circle of possible vendors and partners to very few.

Professional: Storage Administration at a tech services company with 10,001+ employees
In my previous organization, it removed the need for manual tape swapping. Also, offsite tape storage is replaced by replication to a different/central site/device.
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:
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.

We bought it as a stack, racked it together, and it brought efficiency in terms of management, which means we've needed less resources.
Pros and Cons
- "We also really benefit from the GUI capabilities."
- "We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."
What is most valuable?
It's a leading-edge technology with the capabilities it brings. We need to buy less of it, which means it's more economical. We also really benefit from the GUI capabilities.
We're also able to create service stacks that are beneficial across other HP products.
How has it helped my organization?
It makes it a lot more cost-effective because you're not buying ten pieces of technology separately. We bought it as a stack, racked it together, and it brought efficiency in terms of management, which means we've needed less resources.
What was my experience with deployment of the solution?
While the setup was simple because of HP's involvement, it's been complex to run because of a third-party. They put it in a shiny new case and started changing some things. If they'd have left it alone, it would have been fine.
Our partner brought the technology to us, bought it on our behalf, and are running it on our behalf. They told us that they have a lot of knowledge and that they know how to run it, but in reality they don't and have not followed best practices. So now, they're kind of moved out. We're getting our hands around it ourselves, and it's behaving a lot better.
What do I think about the stability of the solution?
We're outsourced with a partner who recalls a larger amount of problems with the product.
What do I think about the scalability of the solution?
We're able to scale it out to other centers.
How are customer service and technical support?
I've used my HP account team, if that counts as technical support. They've been fantastic.
Which solution did I use previously and why did I switch?
For me it was very much a legacy decision. People who were originally involved are no longer with us.
How was the initial setup?
It was fairly simple to set up because we had HP involved.
What about the implementation team?
Our partner implemented it for us, and the results have not been good.
What's my experience with pricing, setup cost, and licensing?
The price puts me off. It's definitely on the high side.
What other advice do I have?
Don't be fooled by other organizations' marketing. Do your homework and make sure it suits your needs.

regarding "Room for Improvement"
As per my experience, there are other ways to enable and disable the deduplication on StoreOnce. but it depends on the installed firmware/software revision. After 3.11.x there are many improvements also it has the option to enable/disable the dedupe option per library, you create.
but, why there is need to disable such great feature which is best of ROI.
Further, deduplication is supported for all VTL, NAS, Catalyst, whichever is created using StoreOnce GUI/CLI supports deduplication.
