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.

Improved read and write performance while simplifying data provisioning and daily management
Its performance is good, but we do have some concerns with Alletra. The challenge I face is that the recent models launched are not available now. When we pitch a solution to a customer and sell HPE Alletra 6000, the customer sees that the product has been discontinued by HPE. The transition of the storage is happening too fast, making it difficult for us, as we normally declare to customers that the product will not reach end-of-life for the next five years. These challenges arise as HPE transitions for the betterment of the product, but we are left answerable to the customer when they ask why we are offering something that the OEM has discontinued. This transition is occurring too fast, and historically, HPE had 3PAR storage that lasted a long time. We need a stable product, and with HPE Alletra, we are unsure about the stability of the product for the next one or two years. Customers now inquire about what happened to Primera storage, which is no longer available, and we lack answers. I feel that HPE Alletra Storage could be improved, as all our competitors offer storage with options for both file and block and object within a single model, while HP still considers HPE Alletra as block storage only. In many government bids, when the government specifies a need for storage that supports both file and block, we lack a solution for that. A customer will not purchase two storages—one for file and another for block—so we need HPE Alletra to come with a solution that accommodates all data types: file, block, and object. This is critical since government purchases often rely on tenders.

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

"It helps to simplify storage because it has an easy front-end to access everything."
"The performance is great."
"The initial setup was really straight forward."
"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"It upgrades in place which means we'll be using it well into the future."
"I am very satisfied with this solution and I would recommend it to others."
"Pure is simple to set up and manage on a day-to-day basis."
"As we needed to grow in capacity, we were able to do so without increasing footprint by replacing smaller devices with larger ones."
"HPE Alletra Storage provides a cloud-like experience on-premises for managing data."
"The solution has been rock-solid since we've had it."
"HPE Alletra Storage is simple."
"HPE Alletra Storage helps simplify storage operations, integrating with vCenter."
"There is ease of use for junior admins. We have VMware integrations for data stores, cloning operations of existing data stores, and InfoSight analytics."
"The features of HPE Alletra Storage that I appreciate the most are the ease of management via CLI, as we have written many homegrown scripts that access the CLI to automate our processes to either increase storage, create snapshots, and refresh snapshots."
"Since we've implemented the solution, we've had zero downtime on the arrays."
"The features of HPE Alletra Storage that I most prefer are its speed, as we were having issues with some of our VMs running into wait time on the older all-flash unit, and moving to the new Alletra's fixed the issue with no tweaking, no tuning, and it's awesome—basically set and forget, as Nimble has always been."
"It's easy to use, has good stability, and many features."
"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."
"IBM FlashSystem provides the same software on each box, including virtualized solutions."
"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 9100 NVMe is easy to use and comes with good performance."
"IBM FlashSystem 9100 NVMe is a stable solution."
"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."
"You get value for money, because the product is good in terms of control failure."
 

Cons

"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"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."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"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."
"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current."
"The best way forward is to continue keeping the product lines within the Alletra brand specialized to what makes them good, ensuring that the features from where 3PAR was good, Nimble was good, and Apollo was good are maintained so that customers who have relied on them can continue to count on their availability."
"According to the characteristics we have seen of the equipment, the licensing could be greatly reduced, given the integration it has with the tools."
"In HPE Alletra Storage, areas that have room for improvement include the network-attached storage, specifically the NFS performance."
"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."
"We have more than traditional use cases. If they could explore new configurations for data storage, it would be ideal."
"Regarding the pricing aspect of HPE Alletra Storage, it is a bit on the higher side compared to Hitachi, but I think they need to work on that since Hitachi offers strong competition with their B26 and B28 models."
"They have a new update coming out that I'm going to be using as far as lack of snapshots. I'm going to put that into place as soon as I upgrade to the new version."
"It would be better if there were an option to incorporate the NVMe feature alongside other storage tiers. Currently, the system operates on Autotier but can manually peer and mix different types of drives, such as SAS and SATA drives."
"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."
"The support could be better."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""
"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."
"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."
"The solution's compression feature could be better."
"We're not satisfied with the deduplication and compression for our volumes."
 

Pricing and Cost Advice

"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."
"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."
"The solution is expensive."
"Pure Storage has not helped to reduce our HANA licensing costs."
"It's expensive, but you get what you pay for."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"There is always room for negotiation."
"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."
"The solution is expensive and can cost around five lakhs."
"The main competitor in the market for HPE Alletra Storage is Dell Storage, as they are selling at a low price."
"HPE was a clear winner on price per terabyte. It was very smooth."
"It is reasonably priced."
"Its pricing is very competitive."
"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."
"It is fairly priced. It is in line with industry standard pricing and cost models."
"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The solution's price is competitive."
"The solution is priced well."
"The price of the FlashSystem 9100 NVMe is reasonable."
"The tool's pricing is competitive."
"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
