AhmedEl-Tayeb - PeerSpot reviewer
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."
"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 catalyst capabilities of the solution is the most valuable feature."
"The speed and deduplication ratio are two of the most valuable features of the solution."
"We have saved time as less is spent on tape handling, and there are fewer hardware issues than with a tape."
"We now have faster more reliable backups, easy replication between data centers and smaller credit centers."
"The product is stable; there are no bugs or glitches, it doesn't crash or freeze, it's reliable, and the performance is good."
"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."
"It is very easy to implement."
"From an operational standpoint it has increased our efficiency and we're able to save a lot of manpower and resources for mundane backup stuff that we've done in the past so that other people can focus on more strategic initiatives in our business."
 

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."
"I would like to see free disk space."
"The solution’s web access should be improved."
"The licence procedures: There is a team for the deployment and there's a team for the licence, but they don't communicate with each other."
"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."
"We wanted to restore the files we backed up, and on three occasions we were not able to, and this got us in a lot of trouble, so I don't think I will take this risk again. Use something else."
"I don't see any new features that we could want or anything that could be done along those lines. Just that we need a bigger machine, so more speed."
"We had one problem when data replication got stuck and we had to ask HP for help."
"The platform's price could be lower."
"It needs to be more versatile to run our tests smoothly."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
 

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."
"The product is not expensive. It is available at a good price."
"I rate the product'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 solution is pretty expensive."
"Price-wise, it comes with a high price tag when compared to other products."
"The licensing costs is capacity-based and come bundled with support."
"The price puts me off. It's definitely on the high side."
"I rate the platform's pricing a seven out of ten."
