Featured Reviews

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.

Lead Consultant - Cloud & Infrastructure Services at Infosys

Delivers essential support and performance for intensive operations in real-time environments

Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.

"The solution is scalable."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"The most valuable feature of this solution is its ease of use."

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

"The most valuable features of this solution are its ease of use and performance."

"What I really like about this program, is that it is easy to use and easy to configurate."

More Pure FlashArray X NVMe pros

"My storage engineers are very happy with PowerMax. They are very pleased with the performance, decreased latency, and dependability. From the team, the RESTful API makes management so much easier for them versus the command line interface."

"Dell support for Dell PowerMax is exceptional, rating a perfect 10 out of 10."

"The uptime is the most valuable feature."

"We can consistently replicate mainframe and open system and have a single recovery point."

"The upgradability and extendibility for the size of the storage unit are noteworthy."

"Uptime by far is the most important thing, and also the replication ability (SRDF). Most of the customers who need this type of availability also want the protection of multiple data centers, and it is able to easily switchover workloads to their other data centers."

"The most important feature or function in Dell PowerMax is the capacity to deliver the required IOPS."

"The product's initial setup phase is easy."

More Dell PowerMax pros

"The solution's licensing policy is more practical and not confusing."

"The implementation is not that complex for someone who has experience."

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

"Quick recovery."

"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."

"The solution saves a lot of storage capacity."

"Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."

"The most valuable features are the deduplication and compression capabilities."

More HPE StoreOnce pros

Cons

"The software layer has to improve."

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

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"In terms of what needs improvement, the dashboard and management could be simplified."

"It is on the expensive side."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

More Pure FlashArray X NVMe cons

"Dell needs to offer more midrange storage options with enterprise-class features similar to the PowerMAX."

"The main feature that I personally want to see is the possibility to upgrade to the next generation without changing all the components and just change the engine, relying on the compatibility matrices between two different generations. Meaning that we could just keep the enclosure and upgrade the engine, integrating the enclosure to the existing pool, then adding automation tools for orchestration."

"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."

"The solution should integrate better with OpenShift and Kubernetes architecture."

"There are so many configurations in the tool that cannot be done by anyone who is not a Dell personnel."

"Dell can improve the Service Level Agreement (SLA) compliance. Sometimes, when we need to replace a component, the SLA says four hours, but for some reason, the technician doesn't arrive until the next business day or even six to eight hours later before the case is placed. So, focusing on respecting the SLA is where Dell could improve."

"They can make the GUI better, especially for the ones that come out of the box. We did encounter a bit of difficulty in setting up the storage. We had to deploy Solutions Enabler on a Linux machine to be able to fully interact with the storage. They need to upgrade the web interface for the management of the storage that comes out of the box. The management interface for NFS is also a bit old and not very intuitive."

"The disadvantage of PowerMax is its cost."

More Dell PowerMax cons

"Cloud integration needs to be simplified."

"The setup phase is not so simple that an end user can plug and play to make it operational."

"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."

"While StoreOnce has many features, it needs to focus on integrating with third-party backup software solutions."

"Its customer service could be faster."

"HPE StoreOnce could improve the capacity support."

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

"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."

More HPE StoreOnce cons

Pricing and Cost Advice

"The product is expensive."

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

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

"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."

"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."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired."

"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."

"Since Dell PowerMax NVMe is an enterprise storage, its price is premium."

"I rate Dell PowerMax NVMe a five out of ten for pricing."

"The labor savings and support have been significant. If we're talking 100 hours of labor every three months, that is 100 hours of a database engineer costs. There are performance latency numbers as well as costs associated with recovering data that gets lost, and this system doesn't lose data. You can look at numbers that go around the cost of downtime, if data is not available. This system doesn't go down. Everyone's ROI is going to be unique, but the dependability and performance of the system combined with its ease of operation will definitely save businesses of all sizes money."

"From a general capital investment, it's one of the higher price points in the market. It depends on the size and software features that you would include in a system. So, the cost varies dramatically."

"Dell PowerMax NVMe's price is expensive."

"Negotiate hard and consider the commercial advantages/benefits to Dell EMC for onboarding your product."

More Dell PowerMax pricing and cost advice

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

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

"The cost of HPE StoreOnce is very expensive."

"I rate the product's pricing a seven out of ten."

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

"I rate the platform's pricing a seven out of ten."

"The solution is pretty expensive."

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