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

"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."

"It is always out of the box, and ready to use."

"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases, and the scale of deployment basically went from several days to a few minutes."

"The tool has reduced our power consumption."

"Do it. I have zero reservations about recommending Pure to anyone who is looking for some really good all-flash."

"Its array houses our entire production environment."

"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."

"Everpure FlashArray is very user-friendly, easy to learn, and makes it easy to identify issues while providing more redundancy on both the controller and host sides."

More Everpure FlashArray pros

"The inline deduplication and data reduction capabilities have been the most valuable."

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

"It has compression, which allows you to store more data than you would normally under the arrays."

"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."

"To be programmatically administered is huge, it is one of the key features that we like about it."

"The setup was quite easy, straightforward."

"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."

"Unity XT is very good compared to Fujitsu and IBM."

More Dell Unity XT pros

"Integration with VMware"

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

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

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

"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."

"The replication feature provides another functionality to protect your data."

"The most valuable feature is the auto-tiering, which helps in the speed of data access."

More VNX [EOL] pros

Cons

"The solution is not cheap."

"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."

"The price of this solution could be improved."

"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."

"The file functionality could be better."

"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."

"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."

"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."

More Everpure FlashArray cons

"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 product’s pricing should be improved."

"There's always room for improvement with the UI. That can be a little cumbersome at times."

"We have had customers reporting issues with slow responses from the support team."

"We would like to see the synchronous replication process included in the next release. Not having this downgraded our performance by 65 percent."

"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."

"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."

"It's not really scalable. Up to mid-range requirements, it's just fine."

More Dell Unity XT cons

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

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

"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."

"Yes, we have had issues. The system is limited by the number of enclosures."

"Make major changes to the file services, Celera, do something like a lite version."

"Poor connection to FC."

"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."

More VNX [EOL] cons

Pricing and Cost Advice

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."

"For us, as the customer, it reduced the price of the management."

"The pricing of Pure Storage FlashArray is reasonable."

"The price is reasonable."

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."

"We have seen a reduction in TCO."

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."

More Everpure FlashArray pricing and cost advice

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

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

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

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

"It is priced at around or under $50,000."

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

"The product’s pricing should be improved."

"Obtaining a warranty is easy."

More Dell Unity XT pricing and cost advice

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

"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."

"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."

"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 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.
