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

"Pure Storage FlashArray has helped us to improve the reporting and the billing cycle."

"We have integrated the solution with VMware, and the process was seamless."

"It's extremely stable and has good performance."

"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance."

"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."

"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."

"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."

"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."

More Everpure FlashArray pros

"The Unity 400 is one of the easiest to manage and the most reliable storage systems that I have managed in my 22 years in IT."

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

"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."

"Stable flash storage platform with good scalability, efficiency, and speed."

"It is stable, I have not personally seen any issues when deploying in a customer environment."

"I would definitely recommend Unity because, compared to VNX and other storage solutions, it is the easiest way to deploy for VMware and physical operating system services."

"It is simple to use and easy to manage. We don't touch it after we set it up."

"The most valuable feature is the fast cache with functionality rewrite."

More Dell Unity XT pros

"I think it's a good solution; it has many benefits and features that are of interest for many customers."

"EMC storage has the best performance and functions."

"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"

"Customer service is top-notch with a dedicated sales and technical resource who are familiar with your environment and spend a lot of time understanding your business needs."

"Depending on how simple the customer needs it to be, might sway my recommendation one way or the other, but in terms of functionality, VNX is very very good."

"In a banking environment, on which we required a very high throughput for our database, we have used this product and our desired response was received."

"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."

"It has a good, high-level of storage."

More VNX [EOL] pros

Cons

"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."

"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."

"The main disadvantage of Pure Storage FlashArray is the price."

"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."

"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."

"In the next release I would like to see integration into other third-party player providers like Google."

"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."

"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."

More Everpure FlashArray cons

"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."

"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."

"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."

"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."

"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."

"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."

"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."

"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."

More Dell Unity XT cons

"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."

"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."

"Storage processor architect for real active/active HA ASIC based functions are needed"

"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."

"It only supports 10Gb copper, and cannot do 10Gb fiber."

"We have had some scalability issues. Scalability options are limited due to the supported SSDs."

"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."

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

More VNX [EOL] cons

Pricing and Cost Advice

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."

"We have an Evergreen Storage subscription, which I think is a great feature."

"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."

"All storage is expensive so any price improvement would help."

"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."

"Cost-wise, it's been very effective."

More Everpure FlashArray pricing and cost advice

"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."

"I rate Dell Unity XT’s pricing a nine out of ten."

"The product’s pricing should be improved."

"It is a good return on investment."

"The license is not required, but we must renew the support every year, every two years."

"This solution offers great pricing."

"Obtaining a warranty is easy."

More Dell Unity XT pricing and cost advice

"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."

"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."

"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."

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

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

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.
