Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"There has been a reduction in the total cost of ownership by around 20%."
"Pure Storage FlashBlade is stable, strong, fast, and modern, and it's an enterprise-class object storage product."
"The number one aspect of FlashBlade is performance; the ability to move large amounts of data through a training array is pretty much unparalleled, and the scalability has been great."
"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."
"The most valuable feature of this solution is performance."
"I love this solution."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"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."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"Dell PowerScale (Isilon) stability is solid as a rock."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"Regarding stability, I find no lagging, crashing, or downtime with Dell PowerScale (Isilon), and it is a highly scalable, stable, and reliable solution that I have experienced."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"One of Cloud Object Storage's best features is infinite capacity."
"IBM Cloud Object Storage integrates well."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"IBM has the most number of additional services, this is the main advantage."
 

Cons

"The Pure Storage Orchestrator is our biggest pain point at the moment."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person, and nine out of ten times, we get an email right back saying that person is off until tomorrow."
"I would also like to see better support for CIFS workloads."
"They need better integration with public clouds along with a better hybrid solution."
"I have not seen ROI."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"The portal is really complicated to figure out features and functions, and it could be easier to navigate."
"I would like to see increased reporting and statistics functionalities."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"The biggest weakness is small file handling."
"The solution can be a bit complex for those not well versed in the technology."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"There is room for improvement in its handling of object storage."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"The performance could be better. You can never achieve the same performance as hardware, and 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."
"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 has limited cloud storage."
"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."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
 

Pricing and Cost Advice

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I understand that it is competitively priced compared to other brands."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"Licensing fees are paid yearly."
"The product is very expensive."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"The pricing for this solution is reasonable."
"The pricing is excellent."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."
"Pricing for this solution is reasonable."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"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."
"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."
"Pricing is not cheap."
