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.

Unified storage solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

Quotes from Members

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

Pros

"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"The compression rate is one of the most valuable features of Pure Storage FlashArray. Additionally, it is all-flash storage with excellent IOPS, and hardware failures are very less."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"Once we solved the data reduction and what Pure does we were hooked."
"We chose Pure Storage because it had the best performance of all the products that we tested."
"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."
"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."
"VMware has benefited our IT organization because we're 100% VMware, everything is running on it."
"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."
"Across the industry, nobody matches it."
"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"I love the SVC."
"We are happy with the support that IBM provides us."
"Our disaster recovery plan tests are always successful, which is good."
"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
"We have all the tools in one place."
"The most valuable feature of the product is that it's very easy to upgrade storage."
"Notable features of Gluster FS include flexibility, scalability, stability, and ease of use."
"The technical support team is excellent."
"It's very easy to upgrade storage."
"If it is designed correctly, it can be used for everything, it has high availability, and that is what we need it for, and the price tag is good compared to the amount of data and high availability provided."
 

Cons

"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"In the next release, I would like to see file-level encryption."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"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 credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"I feel like there is too much automation; the user doesn't have any manual input."
"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."
"The SVC port (virtualized port) is very stable, but the Storwize port is not so stable."
"The feature that's kind of missing is getting us up to the point where we can help the application owners see where their data is at, understand it, and potentially help us breakout."
"Technical support at IBM is actually not as great as it used to be. It seems like IBM has decreased the number of people who can support this environment."
"Sometimes IBM documents something, but in the real world, it doesn't work."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"Technical support is sometimes good and sometimes okay."
"The case logging process is efficient, but resolving software problems takes too much time."
"There is a feature in Red Hat’s commercial version that could be beneficial if integrated into the open-source version."
"In terms of improvement, my initial suggestion would be that the user interface could be simplified."
"The performance of the solution must be improved."
"The system should be more intuitive and easier to manage."
 

Pricing and Cost Advice

"The price is reasonable."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"I don't know the exact cost but it's around $1,000."
"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."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"The pricing is very attractive and it delivers performance for the money."
"We have an Evergreen Storage subscription, which I think is a great feature."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"It has a lot of advanced functions for a reasonable price."
"This solution came as an additional cost for the TSM package we chose."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"We would like the CPU cycle to save more on the licensing costs for us."
"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."
"If you need cheap storage, but still need high availability, it's a good product to look at."
