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.

Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

High-speed data processing has improved billing cycles but performance headroom still needs growth
In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture. Data resiliency can be a concern because IBM can reach up to only four controllers, while others like Dell EMC can support up to eight controllers with better resiliency without service staff. Additionally, the SBC one benchmark is a storage performance console that stresses different storage solutions like Dell EMC and NetApp. It generates metrics of IOPS and latency, showing that the competition can have two million IOPS, significantly outperforming IBM's capabilities. As for the capability of scaling, we can see the limitations in reaching such high-performance levels.

Quotes from Members

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

Pros

"I would definitely suggest this solution to a colleague because of the ease of use."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"Pure is simple to set up and manage on a day-to-day basis."
"If you factor in the ease in terms of operations, as well as the cost of the array compared to other solid state arrays, it becomes a clear positive for Pure Storage."
"Pure gives us better compression, it's easier to manage, a lot less hands-on, and the biggest selling point for me was the replacement of the hardware, the controllers, without any major expense to the clinic."
"It gives us capacity planning."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"User friendly management interface."
"I think the v7000 is versatile, reliable, and gives really good performance in the configuration you choose."
"Go ahead and implement it. IBM storage provides you everything that you’ll need for a block-level architecture, as they have many different products which provides you with a variety of options to meet your needs."
"The valuable features of IBM FlashSystem include flash copy mapping, which is a procedure to collect instant point-in-time data for testing real data."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"The most valuable features are flexibility and performance."
"It's a really reliable, powerful platform; it's a mature product, like a BMW that evolves consistently, with storage virtualization, easy volume migration, stretch capabilities, Site Recovery Adapter, backup integration using flash copies, and everything you need to build a robust disaster recovery solution around it."
"The valuable feature is autoscalling."
"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."
"IBM FlashSystem is an excellent product."
"The high performance and high availability improved our overall processes."
"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."
"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."
"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."
"Good performance with a user-friendly UI."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
 

Cons

"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I feel like there is too much automation; the user doesn't have any manual input."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"It can go down from time to time, but it's been pretty solid so far."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"I would like to see more cloud integration."
"Events/log analysis tools."
"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."
"We sometimes had a problem with some bugs in FlashSystems. One time, one FlashSystem was burnt up. There was some smoke and the data was damaged."
"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."
"There could be some extra features added."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture."
"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."
"The support could be better."
"The pricing should be more competitive."
"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."
"The tool's architecture is complex. It also needs to add data utilization reports."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
 

Pricing and Cost Advice

"There are no licensing fees or other costs."
"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."
"The price is reasonable."
"There are no fees for licensing. The hardware is paid for only once."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"The licensing is $100,000."
"There is an annual or perpetual license required for this solution."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"This is an expensive product and if the price were reduced it would be better."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"The price is a little bit high so is rated a six out of ten."
"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."
"The tool's pricing is competitive."
"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."
"Compared to its competitors, IBM's offering is the most cost-effective."
"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."
"The solution's price is competitive."
"The solution is priced well."
