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.

Pros

"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."
"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."
"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"Before we used HP StoreOnce, the backup was stored on DAS, which was fine until you have a problem in a disk and lose all your data."
"The most valuable is the deduplication ability, but file sharing is also really good."
"Adhoc restores are now resolved in a sensible time frame"
"Its catalyst store and deduplication are valuable as it saves disc space."
"The product was easy for me in terms of architecture, deployment and support."
"The product has really improved the backup and restore for our infrastructure."
"It is very easy to implement."
"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."
 

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."
"I would like to see free disk space."
"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."
"They could provide more options for storage capacity."
"The performance of NAS/CIFS Shares on a StoreOnce is acceptable for a standard write operation, but performance during restores (such as Virtual Machine Restores from Veeam Backup and Replication) is unacceptable."
"The initial setup is quite complex and difficult."
"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."
"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."
"The solution's pricing could be improved."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
 

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."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The solution is pretty expensive."
"The product is not expensive. It is available at a good price."
"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."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"I rate the platform's pricing a seven out of ten."
"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's cost is above average."
