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.

Provides good stability and is reliable in terms of performance

The solution is reliable in terms of performance They should include a snapshot feature for the solution. We have been using the solution for two to three years. The solution is stable. We have 60 solution users in our organization. The solution's initial setup process is easy. It takes three…

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

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

"I appreciate the performance."

"It has good, reliable, fast storage."

"The solution is scalable."

"The latency is good."

"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."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

More Pure FlashArray X NVMe pros

"Lenovo ThinkSystem DE Series is simple to use"

"The solution is very easy to set up."

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"Its initial setup process is easy."

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

"The solution's initial setup process is easy."

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

More Lenovo ThinkSystem DE Series pros

"The solution is useful for machine learning and scientific applications, including computer simulations."

"This has been one of the most reliable storage systems that I have ever used."

Cons

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

"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."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"They could add more support for file storage and different types of storage."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"The tool's pricing is higher than competitors."

More Pure FlashArray X NVMe cons

"In the next release, I would like to see support for Hyper-converged infrastructure."

"The solution could be more scalable, although it suits our present needs."

"Its performance could be faster."

"It would be useful to have structured solutions replicated to other sites."

"The product could support advanced software integrations."

"The features are limited."

"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."

"There could be a snapshot feature in the solution."

More Lenovo ThinkSystem DE Series cons

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

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 VMware, we pay $300,000 annually."

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

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

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The best thing about this solution is its price, which reduces our costs."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The pricing for this solution is good compared to HP or Dell EMC."

"It is an expensive solution."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"We have a five-year contract for providing support."

"The pricing is fair and low compared to other products in this category."

"The solution's price could be better."

More Lenovo ThinkSystem DE Series pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
