Sales Manager at MCS
Has offered a cost-effective option with solid results but requires automation features for better efficiency
For ExaGrid EX, I would appreciate additional features such as backup and restore, automation processes, and automation software for backup and restore processes. I mention that some additional features may be provided by VMware or Dell as support for the hardware they are selling, but ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks. I am not in a situation to provide an exact answer for what I would specifically improve in this regard.

Collaborate effectively with partners and benefit from robust data management capabilities
The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"Both the pricing and the performance are excellent."
"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."
"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
"HPE have better support - hardware and software - compared to the competition."
"The implementation is straightforward."
"In terms of the way that we feel, or the way that I feel about StoreOnce, I think it definitely provided us with the opportunity to give the business something it never had before, and that is a true guarantee to the data that we have."
"Backups are much more optimized, and we can take more backups and more often because of data deduplication."
"Most important criteria to look for includes: Price, features, functionality, and ease of use; definitely look at this solution as a viable option as it is cost effective and reliable."
"HPE backup systems are very good products, easy to manage, with very good performance, a lot of ongoing new development, and good integration with many backup or storage products."
"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."
 

Cons

"The solution’s web access should be improved."
"ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks."
"I would like to see free disk space."
"We selected this as a method to improve and better scale our backup deduplication, but it turned out StoreOnce introduced enough inconsistencies and incompatibilities, we actually went back to Commvault’s native deduplication."
"In order to import tapes from StoreOnce, we had to identify the ID of the items in each store on the appliances, and then create them manually on the HP Data Protector."
"Look elsewhere – you can’t change something once you have it, and it accomplishes what it needs to, but it's not leading edge enough to address the new technologies out there."
"StoreOnce doesn’t work for our class of data, which is small, and needs to include more genomic and medical research as test cases."
"Scalability can become an issue once you grow past the capacity of a single cluster pair."
"We did some calculations on, when it says in the sales sheet that we got this number of terabytes, but the system itself uses some terabytes. So what we ended up with was having 10 or 11 terabytes less than HP actually said that it would contain."
"With the older firmware we did have problems with the B6200 crashing with kernel problems, though this has now been addressed with the firmware updates."
"The solution's technical support should be faster."
 

Pricing and Cost Advice

"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"I rate ExaGrid EX ten out of ten for pricing."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"There are costs for additional storage and space."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The product is not expensive. It is available at a good price."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The solution is pretty expensive."
"The price puts me off. It's definitely on the high side."
