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

"We are very happy with the data deduplication and compression ratio that we have on the platform."

"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 most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."

"The tool has reduced our power consumption."

"They are quite responsive and our local team was pretty good."

"Technical support is very good."

"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."

"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."

More Everpure FlashArray pros

"From my experience, EMC provides good support, and Dell's service is very good."

"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."

"The All-Flash models are pretty fast for the vast majority of our remote workloads."

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

"The Unity platform is really easy to use; when it comes to provisioning and management, it has reduced complexity and improved productivity."

"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."

"We were able to retire all our VNX systems and reduce the footprint in the data center, and the Unity systems can scale up quickly, so we use less space in the data center if we employ more Unity systems than the old VNX systems."

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

More Dell Unity XT pros

"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."

"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."

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

"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."

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

"It would be a good choice for midrange businesses due to the performance/features and cost."

"Integration with VMware"

"Since implementing VNX, we achieved a 10 times increase in the performance for its end users."

More VNX [EOL] pros

Cons

"They could improve the price."

"CIFS and SMB Shares cannot be mounted directly."

"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."

"The initial setup of the product is complex."

"Self-backup is the only feature lacking in this solution."

"It was not proactive communication."

"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."

"I would like to migrate to the cloud in the future and know how that would actually work with this product."

More Everpure FlashArray cons

"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."

"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."

"We have had a lot of issues. We've got massive issues at the moment with IBM AIX, it's not stable, we have a lot of disk errors, production crashes sometimes, and that's not good for a retailer."

"It needs more functionality and the ability to move across more landscapes."

"To the best of my knowledge, migration from VNX to Unity without VPLEX/RecoverPoint is not available right now."

"Perhaps the user interface could be better."

"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."

"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

"The migration process was very complex."

"With this product, the licensing software and capacity are very expensive."

"If the VNX had embedded encryption, that would be great."

"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."

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

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

"There were scalability issues, the scalability options are limited due to supported SSD."

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

More VNX [EOL] cons

Pricing and Cost Advice

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

"The solution could be cheaper."

"We purchased a license to use this solution and we pay for the storage ourselves."

"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."

"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."

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

"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."

More Everpure FlashArray pricing and cost advice

"Our CAPEX was close to $42,000 and operating costs are below $1000."

"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."

"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."

"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."

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

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

"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."

More Dell Unity XT pricing and cost advice

"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."

"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."

"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"

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

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

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.
