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.

A solution with a simple configuration and good stability but it's quite expensive
Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

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.

Quotes from Members

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

Pros

"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"Remote assist is a valuable feature that supports customers and engineers in troubleshooting and resolving issues, allowing for easy problem identification and repair."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"Overall, I am sure that Everpure FlashArray is the best option on the market."
"The seamless integration into the public cloud has improved my organization."
"They have a very good support system, and the GUI is also very intuitive."
"Pure Storage has the right business model and will be around for a long time."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"The most valuable feature is definitely the always-on data deduplication."
"The stability of the solution is very good."
"Implementation of the solution is very simple."
"Kaminario allowed us a solid state solution with marginal incremental cost."
"The price of this solution is good."
"The Lenovo ThinkSystem DM Series is a stable storage system."
"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."
"Lenovo offers a good variaty of Storage Systems. Starts with DS, then DE and the most sophisticated version - DM-Series."
"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."
"In summary, this is a good product and is one that I recommend."
"The solution offers very good reliable systems and storage for our clients."
"The FlexClone feature is the solution's most valuable aspect."
 

Cons

"The number of Filesystems is limited, which it is not on the EMC VNX."
"The solution could improve by having a multi-tenant feature."
"Scalability is not an easy option for Pure Storage, so you have to be very careful when you are getting that product for you."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"It is a bit expensive."
"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"The management graphical interface needs more improvement."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like them to come down in price."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"The interface look and feel could be improved."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"The tool's pricing is high."
"The licensing model needs to be revisited. It needs to be simplified."
"In comparison with other similar solutions, I think this one is the most expensive."
"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."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
 

Pricing and Cost Advice

"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"FlashArray is expensive, but the quality justifies the price."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"It is a cheaper solution."
"I would rate it a seven out of ten for pricing. It could be improved."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"The price is very reasonable when compared to other solutions."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"Kaminario is very competitive on price. They also have a pay per TB model."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"The licensing is all-inclusive."
"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's pricing is similar to Dell and HPE."
"The solution is highly-priced."
