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."
"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."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"We now have faster more reliable backups, easy replication between data centers and smaller credit centers."
"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."
"Due to high speed and multiple simultaneous backup sessions our backup window is reduced remarkably, data throughputs are mentioned as follows: Up to 100 TB/hr of backup performance with StoreOnce Catalyst, up to 40 TB/hr of native backup performance, up to 40 TB/hr of restore performance."
"With 3PAR and with StoreOnce, we kind of have an end to end solution for the customer."
"Nothing's perfect, but the speed we get from the system, the deduplication we get from the system, the replication, it all works as designed."
"The ease of use is excellent and the price point is very competitive."
"Technical support is quite good."
"I would highly recommend this product."
 

Cons

"I would like to see free disk space."
"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."
"Some models are shipped with one power supply by default, even when redundant PSUs are supported in pairs; be aware of that."
"Its customer service could be faster."
"The initial installation and configuration into the network and the integration into the infrastructure needs some improvement, but it's not too difficult if you plan right."
"They could provide more options for storage capacity. At the moment, they only have an 80-terabyte storage facility."
"Scalability can become an issue once you grow past the capacity of a single cluster pair."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"The solution must provide backup options for smaller capacities."
"If it had a little more functionality with other platforms, it would be rated higher."
 

Pricing and Cost Advice

"I rate ExaGrid EX ten out of ten for pricing."
"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The product is not expensive. It is available at a good price."
"Price-wise, it comes with a high price tag when compared to other products."
"The price of the product is reasonable."
"The licensing costs is capacity-based and come bundled with support."
"The solution's cost is above average."
"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 solution is pretty expensive."
