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.

Data management operations are streamlined with impressive metrics and responsive support
Improving HPE Alletra Storage is challenging to answer because there are several different metrics to consider. From a performance perspective, the improvements and large jumps are fantastic as is. From a deployment perspective, I was a big fan of the on-premise deployment model and then connecting it afterward to GreenLake. Now that's being sunsetted. From a sensor and metric standpoint, there is just enough data without getting useless metrics, where you become blind to what it provides. The HPE Storage Technical Assistance Center is still probably the best out of all the storage vendors. It's difficult to improve upon being able to call in and get assistance almost instantly.

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

"The code upgrades are very smooth."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"The tool has reduced our power consumption."
"I cannot imagine my workflow without Everpure FlashArray because I do not have any other type of storage in use."
"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"For an organization, it can take storage from 40 terabytes down to five terabytes."
"It's actually very stable"
"One feature that's particularly valuable for our finance customers is Pure Storage's safe mode. It protects against ransomware attacks by taking snapshots. Our customers were very impressed with this capability. The data reduction is also impressive compared to other providers."
"HPE Alletra Storage is simple."
"It is the simplicity of the deployment. They have unified all the features they have."
"HPE Alletra Storage helps simplify storage operations, with a friendly UI that is super easy so users can have a short tutorial and start working on it, while providing predictable performance and capacity for applications and delivering competitive pricing, easy management, and almost 99.999 uptime availability without issues."
"The initial setup process with HPE Alletra Storage is very easy, and I find it straightforward."
"The features of HPE Alletra Storage that I prefer most are the copy of virtual volumes. These features benefit my organization by providing fast performance and low latency."
"My experience with the deployment of HPE Alletra Storage has been good. I like the single pane of glass approach."
"One of the best benefits I can think of is that the support team is top-tier."
"The benefits of using Alletra for my organization are that the amount of time it takes for my team to define storage and allocate storage for projects has reduced, and there's less training, too."
"You get value for money, because the product is good in terms of control failure."
"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."
"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."
"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."
"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."
"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."
 

Cons

"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"We have not had a good experience with the IBM device."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"I would like to see them develop the ability to integrate with more AWS services."
"There are so many features of HPE Alletra Storage that I probably don't even know about, and as a small shop, we probably don't take advantage of half of them."
"I would not like to see any additional features included in the new release of the HPE Alletra Storage. We're still new to the solution. So far, it's fine."
"Licensing is always a challenge since nobody enjoys those costs, though having support going forward gives me peace of mind."
"We had a hiccup when we deployed our last SAN. The 6000 that came in, they were transitioning the onboarding to be fully cloud, GreenLake-driven. The problem was we're in a regulated air-gapped environment."
"We struggle to gain access to senior support engineers. Typically, we need to escalate via sales."
"Maybe they could just reduce the number of racks and the amount of rack space."
"Technical support from HPE can be hit and miss."
"In the perfect world, it would be cheaper."
"The solution's compression feature could be better."
"The tool's architecture is complex. It also needs to add data utilization reports."
"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."
"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."
"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."
"In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture."
"Deduplication and compression should be improved."
"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."
 

Pricing and Cost Advice

"The cost has room for improvement."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"The best features come included without any additional cost."
"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."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"So far, so good."
"The pricing is somewhat high, but when customers choose HPE, they often prioritize the brand value over pricing. The pricing is higher compared to other vendors."
"The solution is expensive and can cost around five lakhs."
"Its pricing is very competitive."
"Its licensing is good. Pricing-wise, there can be a little bit more flexibility. It would help to have different sizes. However, it fits into the budget that we have, so we are happy."
"It is fairly priced. It is in line with industry standard pricing and cost models."
"Its price can be optimized."
"For us, its price is good."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The product has an average cost."
"The tool's pricing is competitive."
"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."
"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
"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 price of the FlashSystem 9100 NVMe is reasonable."
"The solution is priced well."
