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.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

Enables seamless data replication and supports comprehensive data analytics workflows
The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites. Also, important is the capability to provide RESTful APIs for custom connectors. In terms of security, I advise customers to rotate access keys to enhance protection. Additionally, scalability is effortless as you can add nodes or expand the license.

Quotes from Members

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

Pros

"We find the ease of usability and setup valuable."
"We have seen a good reduction in the amount of total storage space that we're using because of the deduplication."
"It is simple, powerful, and a beautiful solution."
"The pricing of the product is very competitive to others in the market for Flash and NVMe storage, and from an ROI standpoint, if you consider compression and de-duplication and all that, you get a pretty good ratio."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"The performance of the storage is just unbelievable."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"The first set up we had was really straight forward and simple."
"Dell PowerScale overall is easy to use."
"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."
"What I appreciate about Dell PowerScale (Isilon) are its best features: it supports both file and object storage, and it is very easy to manage."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"I buy Dell PowerScale (Isilon) because of the price, service, and technology, and the technology that is particularly good for my company is that I have two Dell PowerScale (Isilon) systems in two sites, and I use replication between them with Superna software, which is a third-party Dell technology."
"The tool's most valuable features are high density and scalability."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"IBM Cloud Object Storage integrates well."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"One of Cloud Object Storage's best features is infinite capacity."
"IBM has the most number of additional services, this is the main advantage."
 

Cons

"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"I would like to see them lower the costs."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"I would love for them to have a hyper-converged solution."
"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."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"We would like to integrate it more with our backup solutions."
"The pricing could be reduced."
"The initial setup for this solution is complex."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"The UID mapping and how to configure mapping-related things is a struggle."
"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."
"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."
"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"IBM Cloud storage is not cheap, but it could be."
"One improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
"IBM Cloud storage is not cheap, but it could be."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The price is reasonable."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The price of Pure Storage FlashArray is expensive."
"It could always be lower, but it's okay."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"We feel that the pricing is fair and the licensing process was easy for both."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"The pricing for this solution is reasonable."
"It is an expensive solution."
"The price of the solution is high."
"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"The price of Dell PowerScale (Isilon) is reasonable."
"The solution's licensing cost varies based on capacity and performance requirements."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"Pricing is not cheap."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
