Chief Technology Officer at Lambda256

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

User interface offers clarity and detailed information while technical support consistently delivers

The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.

Quotes from Members

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

Pros

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

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

"The latency is good."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"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 database workloads are pretty fast because I frequently move data from here to there."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"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 most valuable feature is the ability to replicate. We are running a financial company and it needs to be available 24/7. We can't afford any downtime."

"There's some new stuff coming with 7.3, which just got released, where they're spreading the sparing across the whole array, rather than having a dedicated spare disk, and have it sit there and do nothing until one of them dies, and then it kicks in - and having to rebuild all of that. Now, they'll do the sparing across all the disks and they say that is going to add not only space but performance to the array, with 7.3."

"Connecting it up, you can run it within a few hours."

"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."

"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."

"I've found the stability to be very good."

"The user interface is good, I would rate it a nine out of ten."

"It is fast and performs well."

More Dell SC Series pros

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

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

"Its initial setup process is easy."

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

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

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

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

Cons

"The UI for this solution needs to be improved."

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

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

"It is on the expensive side."

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

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

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

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

More Pure FlashArray X NVMe cons

"I would like to see higher compression, dedupe, faster I/O, and bigger drives."

"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."

"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."

"An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down."

"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."

"The configuration could be easier in Dell EMC SC Series."

"The initial setup is somewhat complex and should be made simpler to do."

"Some menus aren't so intuitive."

More Dell SC Series cons

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

"The product could support advanced software integrations."

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

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"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."

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

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

Pricing and Cost Advice

"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."

"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."

"The product is expensive."

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

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

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

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

More Pure FlashArray X NVMe pricing and cost advice

"It's a very affordable solution."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"It has a good price point and offers some value-added enterprise features."

"Compared to other solutions out there, it's affordable."

"We have reviewed many platforms over the years. It is probably the best solution for its value."

More Dell SC Series pricing and cost advice
