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.

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

"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."

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

"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."

"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."

"The GUI is very easy to use and intuitive."

"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."

"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."

"All my customers are pretty happy with most Pure Storage solutions."

More Everpure FlashArray pros

"It’s helped with the overall stability of our VMware environment."

"The solution allows for easy, useful replication with good features for VPLEX and VIVO."

"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."

"Unity is very stable."

"We use it to implement all our VDI solutions."

"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."

"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."

"I have found Dell EMC Unity XT to be stable."

More Dell Unity XT pros

"Good performance for VM environments"

"It’s very stable in all the years I've worked with it, I know it’s stable and the support is there."

"Technical support is good."

"In one cabinet, we have many environments: VMware, Oracle, Adabas, NAS (CIFS and NFS resources), and mix disks on tier configurations Tier configuration with different disks (SAS, SATA, Flash) The software for management is very user-friendly Snapshots for backup and refresh development on test environments"

"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."

"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."

More VNX [EOL] pros

Cons

"The solution is not cheap. It's much more expensive than DataCore."

"Storage. There could be better storage."

"The solution is not cheap."

"I would like to see them develop the ability to integrate with more AWS services."

"I would prefer that they lower their pricing."

"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."

"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."

"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."

More Everpure FlashArray cons

"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."

"Ordering is easy, but the processing site and working with those companies was difficult."

"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."

"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."

"The reports could possibly export all the data at once."

"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."

"The interface can be a little challenging for someone new."

"The user interface could use improvement."

More Dell Unity XT cons

"It is not the easiest product to implement and manage, especially on the NAS side, but that is now fixed in its successor product from Dell EMC called Unity."

"I do not recommend the Gen 1 VNX to anyone in this day and age."

"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."

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

"They may change the disks from NL-SAS to Flash, but it would be costlier for customers."

"The CLI could be better documented, like with VMAX."

"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."

"Oracle is never the cheaper solution. Compared to others, it is always among the most expensive."

More VNX [EOL] cons

Pricing and Cost Advice

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."

"Price per terabyte is substantially higher than their competition. We would like to see it drop."

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

"I don't know the exact cost but it's around $1,000."

"Pure Storage has not helped to reduce our HANA licensing costs."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

More Everpure FlashArray pricing and cost advice

"Licensing is easy since all the software is included."

"While Dell EMC is costly, I don't have any complaints about their licensing model."

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"The price of Dell Unity XT could improve. However, it is a one-time purchase."

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."

"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."

More Dell Unity XT pricing and cost advice

"The initial pricing and licensing are reasonable, the 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."

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

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

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

"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."

"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.
