Featured Reviews

AhmedEl-Tayeb - PeerSpot reviewer
Sales Manager at a tech consulting company with 201-500 employees
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.

HPE Product Manager at a tech services company with 51-200 employees
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

"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."
"Both the pricing and the performance are excellent."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"The implementation is straightforward."
"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."
"If you purchase the product, you will have peace of mind."
"We have a high-tech solution in the data centre which will support us as we follow the company strategy in the coming years."
"The size of the backup data is very small, which is one of the features that we really like."
"The most valuable feature of HPE StoreOnce is the virtual drive."
"The hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."
 

Cons

"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."
"The solution’s web access should be improved."
"I would like to see free disk space."
"One of the drawbacks of this product is that you cannot add another disk array when you reach capacity."
"That can be difficult and frustrating at times, but over ten years working with them, I would say today it's probably a little better than when I first started."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"From a feature functionality perspective I think overall having some more mobility tied into it, having the ability to have applications that you can use on the go, that can give you kind of an overlay of the overall health and welfare of your data protection and data recovery strategy, being able to do simple things, like having run books."
"While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring."
"I would like to see an emphasis placed on making data deduplication and compression more powerful."
"The auto load balancing between VTL Libraries has been not as efficient as it should have been."
"The web-GUI is not intuitive enough for basic users and offers fairly limited functionality compared to a backup solution such as Veeam or Backup-Exec."
 

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."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"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."
"The product's pricing is medium."
"I rate the platform's pricing a seven out of ten."
"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."
"The product is not expensive. It is available at a good price."
"The price puts me off. It's definitely on the high side."
"HPE StoreOnce is cheaper compared to other solutions in the market."
