Eugene Hemphill

Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Most of our client base is between fifty to five hundred end users. We occasionally recommend high-end HPE products for larger clients needing performance and reliability. Our clients predominantly use HPE StoreOnce for small business purposes in industries like dairy and finance Our clients have…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It has benefited my organization because it has reduced time to insights."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"It has good, reliable, fast storage."

"The latency is good."

"I appreciate the performance."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

More Pure FlashArray X NVMe pros

"The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance."

"Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access."

"It's easy to backup data, manage. A"

"The solution is stable."

"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."

"The implementation is straightforward."

"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."

"The scalability is very good."

More HPE StoreOnce pros

"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

"It has been a perfect fit for the workload that our customer is doing."

"The solution offers very good reliable systems and storage for our clients."

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

"Scalable and stable storage array."

"The servers are fast and affordable."

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"Maybe the price can be reduced since the solution is very expensive."

"Adding some functions to the product would be beneficial."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"The software layer has to improve."

"The tool's portfolio is minimal. It is expensive."

"There are some challenges with data encryption and reduction."

More Pure FlashArray X NVMe cons

"Its customer service could be faster."

"The platform's price could be lower."

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

"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."

"We have lost some market due to the minimum capacity now being 80 terabytes."

"HPE StoreOnce needs to provide a SaaS solution by offering high-density disks."

"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."

"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."

More HPE StoreOnce cons

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."

"The licensing model needs to be revisited. It needs to be simplified."

"Lenovo could have a wider variety of storage solutions in the NAS space."

"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."

"This is an expensive solution."

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"We pay approximately $50,000 USD per year in licensing fees."

"Our licensing fees are $500,000+ USD."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"As far as the licensing costs, everything is included in the license."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Given its price, Pure is not the first option."

More Pure FlashArray X NVMe pricing and cost advice

"The licensing costs is capacity-based and come bundled with support."

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

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

"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."

"There are costs for additional storage and space."

"The cost of HPE StoreOnce is very expensive."

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

More HPE StoreOnce pricing and cost advice

"The solution is highly-priced."

"The solution's pricing is similar to Dell and HPE."

"The price of the Lenovo ThinkSystem DM Series is good."

"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
