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.

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."

"Both the pricing and the performance are excellent."

"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."

"HPE StoreOnce works well, it is stable."

"If you have a large enough storage capacity then you can take an ample amount of data."

"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."

"The interface is very user-friendly."

"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."

"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."

"HPE StoreOnce has high performance."

"HPE StoreOnce is an easy-to-use tool."

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."

"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 user interface of HPE StoreOnce is an area of concern where improvements are required."

"The product's price could be better."

"The solution's pricing could be improved."

"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."

"The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."

"This product would be improved with the inclusion of more features to security or WORM."

"They could provide more options for storage capacity."

"I would like to see better integration with Veeam software."

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."

"I would rate it around two or three because, compared to others, it tends to be higher priced."

"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 cost of HPE StoreOnce is very expensive."

"Price-wise, it comes with a high price tag when compared to other products."

"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."

"The product is not expensive. It is available at a good price."

"The product's pricing is medium."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

Overview

ExaGrid's disk backup with deduplication system is purpose-built for backup that leverages an architecture optimized for scalability, performance, and price. The system scales as needed by adding ExaGrid appliances, which virtualize into a GRID architecture automatically, adding capacity and processing power while acting and being managed as one unified system.

ExaGrid disk-based backup appliances include GRID computing software, which virtualizes them into a single pool of long-term capacity. Capacity load balancing of all data across servers is automatic, and multiple GRID systems can be combined for a total logical backup capacity of 16PB.

ExaGrid

HP StoreOnce Backup is a data backup solution that provides a consistent, high-performance, scale-out architecture for your entire enterprise. Reduce the amount of backup data capacity by 95 percent, and choose between powerful dedicated appliances for data centers, or flexible virtual appliances for smaller and remote offices.
