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.

Ease of implementation and robust performance enhance multi-OEM support experience

We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

The Nimble CS-Series has proven to be reliable with 100% uptime

When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

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

Pros

"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

"This solution has improved my organization because it has good performance."

"Performance, dedupe, and that it works well with database workloads are its most valuable features."

"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."

"The availability and ease of use are the big features."

"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."

"Pure Storage is seen as a visionary company with leading edge technology."

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."

More Everpure FlashArray pros

"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."

"You can add volume and it's automatically registered in VMware."

"The most valuable aspect of this solution is that it's a single block, a complete block that includes both NAS and SAN."

"We use replication for disaster recovery (DR), making our DR process much easier."

"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."

"They find the performance amazing from what they're coming from."

"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."

"Performance is a top feature."

More Dell Unity XT pros

"It’s amazing, you can add and stack, and add more elements."

"Multi-tiering, positively affects the efficiency of the storage space."

"The replicating of the entire storage unit to a different location was a very useful function."

"I really value deduplication and compression to save space."

"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."

"Stability has been rock solid, as we have been running both units for over two years with no major problems."

"It is very stable, even during multiple power failures."

"If you are looking for a stable, powerful and effective entry level SAN that you can provision on your own for a small environment or a small office/remote office situation - this is definitely the product for you."

More VNX [EOL] pros

Cons

"It's expensive, but you get what you pay for."

"The price of this solution could be improved."

"I would like to see them lower the costs."

"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."

"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."

"In the next release, I would like to see file-level encryption."

"Automation could be simplified."

"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."

More Everpure FlashArray cons

"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."

"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid."

"It isn't easy to find trusted partners for the product. The solution has issues with mid-level storage and does not come with enterprise storage."

"I would like the UI to look better."

"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."

"The product’s pricing should be improved."

"Scalability of this solution could be improved."

"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."

More Dell Unity XT cons

"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."

"EMC wasn't able to fix the issue, so they had to stop using snapshots."

"EMC pricing is too expensive, like the Apple brand iPhone in the cellphone market."

"The performance impact snapshotting had on the cluster was enormous. The entire cluster performance took a performance impact of about 30% as soon as we created one snapshot of all the volumes created on the cluster."

"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."

"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."

"Poor connection to FC."

"VNX can improve by offering flexible upgrade options."

More VNX [EOL] cons

Pricing and Cost Advice

"We have seen a reduction in total cost of ownership (TCO)."

"Because of the SSD, it is cheaper because I am not purchasing so many disks."

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"The licensing is $100,000."

"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."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"The price is very reasonable when compared to other solutions."

"It's expensive, but you get what you pay for."

More Everpure FlashArray pricing and cost advice

"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"The solution should be cheaper."

"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."

"Pricing for this product is manageable, though slightly higher than comparable products."

"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."

"The solution is very expensive."

"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."

More Dell Unity XT pricing and cost advice

"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."

"Reducing dependency on JavaServer Pages (JSP) could improve the administrative overhead."

"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.
