Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Complicated deployment and poor support persist, affecting overall satisfaction
The deployment process of Lenovo ThinkSystem DM Series is very complicated compared to previous GUI systems. Many customers have lost data while configuring it, indicating a need for improvement. The after-sales service is also very poor. Furthermore, it does not offer basic features like deduplication, and the service is generally considered to be very bad.

Gives us the foundation to grow efficiently
We're a manufacturer. All of our ERP software is dependent upon fast performance and connection to this hardware. So when there was an issue years ago when something was wrong or slow, that prompted us to say, "Can we check storage? Can we check the network?" Ever since we've gone up to all-flash FAS systems, there's never any questions about performance when it comes to storage. There's been a huge leap from spinning disks to SSDs. I'm hoping with the next update, we'll go to NVMe and we'll have similar experiences. Last year, we refreshed the SAN at our headquarters. We signed a Keystone agreement with the ability to pay for storage as a service at an excellent price point yet still have the hardware on-prem. I manage the hardware, and, for me, it's the best of both worlds. We've just come up with a situation where, finally, after some time, we're going to need to buy some additional storage. In previous situations like this, it usually meant the purchase of an additional shelf at a large price. Now we have Keystone, and we're locked in at that price per tebibyte. We just have to say that we want to add 25 tebibytes and they take care of it. It's worked out really well. We work ISO 27001 certified. Since I manage the enterprise storage, we use SnapMirror, and we're currently using Veeam for backups. Thanks to what this tool provides, we are able to get through that portion of our certification without a problem. No changes, no rectifying. It's very slick. Our company's goals include maintaining a level of consistency. We're never going to be on the bleeding edge. We're never going to have the super fastest abilities. We want something that works, is easier for us to manage, and has a better growth path. For us, in the past, in the need for additional disk space, if we didn't do the sizing right in the first place, buying additional disks was incredibly expensive. Now, with Keystone, that's no longer an issue, and that's what we like.

Quotes from Members

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

Pros

"We have perfect run through times and latency."
"It's simple, powerful, and ready to use."
"I like its speed. It has all the features that I need."
"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."
"They can provide a lot of performance, so there is not a lot of difference, but efficiency is something customers value because the compression can be up to twice of the second competitor."
"If you need a high-performance storage appliance that is easy to install and maintain, you pretty much can't go wrong."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"The management features are well organized and they have a very good dashboard."
"It has been a perfect fit for the workload that our customer is doing."
"The Lenovo ThinkSystem is used for everything in our company from ERP to BI, for production, PLM, CAD for designing, and everything else."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The servers are fast and affordable."
"Ability to cluster two storages together with HA availability."
"The product’s quality of service guarantees the performance of each workload."
"My advice is to try it, because I think DM Series is a scalable all-in-one system with unified block and file storage and cloud tiering."
"We are satisfied with the stability."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"NetApp helps us get the fastest output."
"NetApp support is fantastic."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
 

Cons

"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"In the next release, I would like to see file-level encryption."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"The only thing I think could be improved is price. The price is the main concern for our customers."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."
"Lenovo could have a wider variety of storage solutions in the NAS space."
"The Lenovo DM Series is an excellent storage product, but I think it isn't competitive with other companies like Dell EMC and IBM because IBM products are very cheap and have more features."
"The solution needs a simpler licensing theme around the DM series."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"The tool's pricing is high."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"Pricing could always be lower."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
"Regarding tech support for NetApp, once the engineer understands our problem, they provide solutions that suit our environment; however, it is essential for the engineer to understand that our environment may differ from standard setups, which can sometimes cause discrepancies in recommendations."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"The solution's ransomware protection could be improved."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
 

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"The cost has room for improvement."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"The solution's pricing is similar to Dell and HPE."
"The price of the Lenovo ThinkSystem DM Series is good."
"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
"The solution is highly-priced."
