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

"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."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"Both the pricing and the performance are excellent."
"The deduplication feature is awesome; the storage space has been cut down by at least 50% and on some instances greater reduction has been achieved."
"The solution saves a lot of storage capacity."
"The size of the backup data is very small, which is one of the features that we really like."
"Backups are kind of one of those things where you don't want to worry about it, you don't want to be up at night fiddling with it, and I've probably gone from spending anywhere from maybe four to six hours a week tending backups to about 30 minutes a week."
"The valuable feature is the ability to work with the Veeam software to reduce the backup windows."
"The time to do the backups is great for us because the last backups we used to have took at least 8 - 10 hours and at the moment the backups takes one hour or less."
"It's easy to backup data, manage. A"
"The important feature is compression and duplication. It has a good compression ratio and is very stable."
 

Cons

"The solution’s web access should be improved."
"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."
"We are looking for Federated VTLs just like Federated Catalyst Store. Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."
"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."
"Reporting needs to be worked on."
"HPE StoreOnce needs to provide a SaaS solution by offering high-density disks."
"It needs to be more versatile to run our tests smoothly."
"Maybe when we do restores for Veeam, the way it has to re-hydrate all the deduplicated data, if there's a way to speed that up that would be a good feature, some kind of algorithm or something."
"An improvement would be an improved deduplication algorithm."
"The repository should have an extension to connect to the cloud and deposit the backups."
 

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 price of the product is reasonable."
"The solution's cost is above average."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"The licensing costs is capacity-based and come bundled with support."
"There are costs for additional storage and space."
"The price puts me off. It's definitely on the high side."
"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."
