IT Manager at Regin Dalarna

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.

Account Technology Specialist at a tech vendor with 10,001+ employees

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

"The fact that the solution is extremely stable and it works really great each dollar spent on this solution is worth it."

"We can capacity plan at a greater level than we used to."

"If you are looking for a new storage array, Pure Storage is, what I call 'the new kids on the block' who don't need to pull legacy systems with it."

"The product is scalable and easy to expand."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"It has good flexibility and stability, it's easy to manage and the response time is good."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

More Everpure FlashBlade pros

"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."

"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."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."

"The solution has simplified management by consolidating our workloads, and rather than managing all the different workloads on different storage arrays and Windows Servers, we just have one place per data centre where we manage all their unstructured data, saving us time."

"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."

"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."

"The solution is extremely easy to manage. This is its most valuable feature."

"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."

More Dell PowerScale (Isilon) pros

"IBM Cloud Object Storage integrates well."

"Overall, I rate IBM Cloud Object Storage a ten out of ten."

"IBM has the most number of additional services, this is the main advantage."

"IBM Cloud Object Storage integrates well."

"The integration itself is pretty easy. The access appliances create the connection between both environments."

"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 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 solution is expensive."

"The documentational aspect of FlashBlade needs improvement."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"The integration with S3 needs some improvement."

"The features provided for SMB customers are limited."

"We have one system at a customer's site that has had a lot of problems over the last year — I think maintenance was required over seven times before everything was corrected."

"The feature that we're waiting on is better integration with the cell services."

"I would like to see more VM-Aware features in the next release of this solution."

More Everpure FlashBlade cons

"The solution isn't suitable for small environments or small customers."

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."

"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."

"I would like to see increased reporting and statistics functionalities."

"The solution is expensive. It's quite expensive for the amount of storage we have."

"Sometimes, it takes too long to set up everything. That's something I would want them to improve."

"The price always has room for improvement."

"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."

More Dell PowerScale (Isilon) cons

"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."

"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."

"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."

"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."

"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."

"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."

"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."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price is a little high."

"I feel that the price could always be lowered."

"The pricing for FlashBlade is between cheap and moderate."

More Everpure FlashBlade pricing and cost advice

"It is an expensive solution."

"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."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"Our company finds the pricing high, but it decreases over time."

"The price of the solution is high."

"The pricing for this solution is reasonable."

"The price of Dell PowerScale (Isilon) is reasonable."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"Pricing is not cheap."

"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."

"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
