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.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

Quotes from Members

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

Pros

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is very straightforward to set up."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It has good, reliable, fast storage."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"Provides good provisioning, allowing us to save space."
"Dell Unity XT offers data integration features."
"User friendly interface"
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"We currently have two Dell EMC Unities going. One of them at our primary on-premise DR site. They communicate with each other. If we ever have to failover, it is right there and ready."
"The technical support is very professional and provides quick responses."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"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 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."
"Lenovo ThinkSystem DE Series is simple to use"
"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."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
 

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"The tool's portfolio is minimal. It is expensive."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"There is room for improvement in the pricing of the product."
"We need better data deduplication."
"It is on the expensive side."
"I called about an issue where I couldn't get VVOLs registered. It turns out it is a bug in the code and that there is no information about when it will be fixed. It's just not going to work. I was a little miffed about that."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"Licensing costs could be reduced."
"A customer had to buy VMX because Unity didn't have WORM."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Improvements can be made to the product's performance."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"It would be useful to have structured solutions replicated to other sites."
"The solution could be more scalable, although it suits our present needs."
"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."
"The product could support advanced software integrations."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"With VMware, we pay $300,000 annually."
"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 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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"The pricing of Dell Unity XT is good."
"The solution is very expensive."
"The price is good for commercial grade storage arrays."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"We have a five-year contract for providing support."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The solution's price could be better."
"It is an expensive solution."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The best thing about this solution is its price, which reduces our costs."
"The pricing is fair and low compared to other products in this category."
