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.

Efficient and straightforward setup boosts data management capabilities

Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage. It provides a lot of features suited for complex systems, such as scalability and the ability to define multi-domain systems, which are beneficial for data management and storage separation. It is efficient from the customer's point of view, offering deduplication at both the volume and file levels. The configuration and setup are straightforward, provided one has knowledge in setting up network infrastructure like VLANs. It is easy to install, use, and configure, making it a reliable product.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The solution is very straightforward to set up."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

"The high availability of the product is the most valuable feature."

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

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

"The solution is scalable."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

More Pure FlashArray X NVMe pros

"It was very easy and straightforward to setup."

"The feature I like most about Dell Xtremio is its hardware quality compared to other vendors. It's clear they're continuously improving their research and development."

"The performance is good, which is important."

"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."

"Deduplication and cloning capability"

"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."

"The solution's most valuable feature is its high performance."

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

More Dell XtremIO pros

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

"HPE StoreOnce has high performance."

"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."

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

"The product’s data retention is very good."

"Deduplication is the most valuable feature."

"We also really benefit from the GUI capabilities."

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

More HPE StoreOnce pros

Cons

"The software layer has to improve."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"In the future, I would like to see integration with enterprise backup systems."

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

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

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

"We need better data deduplication."

"There is room for improvement in the pricing of the product."

More Pure FlashArray X NVMe cons

"Get rid of the Java aspect of the GUI console."

"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."

"The product could be improved by reducing the pricing and having better organization in their technical support team."

"I am not too impressed with XtremeIO because we had a major failure."

"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."

"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."

"It needs a way to determine the deduplication of each LUN and what the impact would be if we were to move data from one LUN to another."

"Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience."

More Dell XtremIO cons

"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."

"It is difficult to solve issues with this solution remotely. I prefer to use the knowledge base platforms. The response time could improve."

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

"The dashboard needs more improvement."

"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."

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

"The solution would be improved if it could also be used as a data store for VMware."

"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."

More HPE StoreOnce cons

Pricing and Cost Advice

"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."

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

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

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"With VMware, we pay $300,000 annually."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

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

More Pure FlashArray X NVMe pricing and cost advice

"The initial purchase price was good but when you need to upgrade, it's a different story."

"It's not cheap, but it absolutely gets the job done. I don't have any real comment regarding licensing specifically."

"This is the best flash array on the market for high-end workloads, so expect to pay for that. But the support subscription cost is fixed for seven years, which made it easier for us to plan on the maintenance costs."

"The license for XtremIO is in the box, so you don't have to buy anything."

"It is costly but worth it."

"XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays."

"It is expensive if you need to increase scalability."

"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."

More Dell XtremIO pricing and cost advice

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

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

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

"The cost of HPE StoreOnce is very expensive."

"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."

"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."

"HPE StoreOnce is cheaper compared to other solutions in the market."
