Easy to set up with good data compression technology and useful deduplication

The initial setup is very straightforward. Even upgrading the firmware is very nice. You don't need to shut down. Previously, we used to have a shutdown, and now we hand over to one more processor, upgrade the one processor, and then switch back to this process, and then we'll do the upgrade for the process so there is no downtime. I'd rate the ease of implementation nine out of ten. Since we are holding almost all the data, which are all critical and confidential, the deployment is always on-prem only. It takes a maximum of two to three hours. The solution is almost finalized before ordering. We plan what has to be done, and how many services have to be connected through the HBA. Based on that, the number of fiber ports should have been ordered along with the system. Normally, it comes with two fiber-channel HBA adapters. We used to order with four channels instead of going for a sand switch. We connect three servers directly into process A and process B. Before getting into the server, all the servers should be up and running with the HBA connector with the fiber cable ready. Once we install the server, we will see if the firmware is up-to-date or if it is one month old since the shipment takes at least one or two months before it reaches our hands. If there is any new update, we will check with them to see whether the new firmware is good or if there are any bugs in it. If the support team says there is no bug, it means we will update the firmware and create a pool. If it is a hybrid pool, we'll do a mix and combinations of flash as well as the NSS for the images. For the data, we have only the flash itself, and we use a rate six for the data. Previously, with the regular SaaS drives, we used to have a rate ten; however, with the flash drives, we used to have rate five or rate six only. Normally, in-house inside the rack, we need two people. Otherwise, one engineer itself will do. If it is a flash drive, only one person itself will be enough. If it is three bay drives with 144 TB or 288 TB, then we'll go for one more person to fix inside the rack. Once it is fixed, the installation will be done only by one person. For maintenance, normally, we check the firmware updates within a month, or we check every 30 to 45 days to seek out firmware updates. We provide maintenance to our customers. For other issues, we might call technical support. Most things we can manage.

Meets requirements for hosting our Virtual Machines in three data centers

The demand in the market is for hyper-converged, all-in-one virtualization. It is not only for the operating system or hypervisors but also for networking and security. It is about optimum solutions. This is a solution that I recommend for those who need the basics that can be achieved with a rack mount server. I would rate this solution an eight out of ten.

Quotes from Members

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

Pros

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"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."

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

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

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

"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."

"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 feature of this solution is its ease of use."

More Pure FlashArray X NVMe pros

"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."

"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."

"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."

"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."

"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."

"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."

"User friendly interface"

"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."

More Dell Unity XT pros

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

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

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

"Lenovo ThinkSystem DE Series is simple to use"

"Its initial setup process is easy."

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

"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."

More Lenovo ThinkSystem DE Series pros

Cons

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

"We need better data deduplication."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

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

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

"There are some challenges with data encryption and reduction."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

More Pure FlashArray X NVMe cons

"The initial setup is not so straightforward if you don't have experience with storage arrays."

"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."

"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."

"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."

"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."

"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."

"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

More Dell Unity XT cons

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

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"Improvements can be made to the product's performance."

"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."

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

"The product could support advanced software integrations."

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

"The features are limited."

More Lenovo ThinkSystem DE Series cons

Pricing and Cost Advice

"The licensing is on a yearly basis."

"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."

"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."

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

"The product is expensive."

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

"This solution offers great pricing."

"It is a good return on investment."

"The solution is very expensive."

"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"Our costs are roughly $200,000 a year."

"While it has a good price to start, they could always make it cheaper."

"There is not a license required for the use of the solution. We purchased a maintenance contract."

More Dell Unity XT pricing and cost advice

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

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

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

"The solution's price could be better."

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

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

"It is an expensive solution."

"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."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."

The DE All-Flash Series delivers the performance of more than 2,000 15k rpm HDDs, yet requires only 2% of the rack space, power, and cooling. Because it consumes 98% less space and power, DE Series can significantly improve the overall efficiency of your IT operations while continuing to meet your performance requirements.
