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.

More Pure Storage FlashBlade pros

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."

"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."

"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."

"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 features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."

"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."

"The most valuable features of the solution are flexibility and ease of implementation."

More Dell PowerScale (Isilon) pros

"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."

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

"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."

"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."

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

Cons

"The speed could be improved."

"The documentational aspect of FlashBlade needs improvement."

"The features provided for SMB customers are limited."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"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."

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

"It would be nice if you could store file-based in the same box with the same technology."

More Pure Storage FlashBlade cons

"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything."

"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."

"The price of the solution could be reduced."

"The portal is really complicated to figure out features and functions, and it could be easier to navigate."

"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 replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."

"The downside of Dell PowerScale (Isilon) is that if we are replacing a drive, sometimes in the worst-case scenarios, some of the other drives will also go to the SmartFail state."

"Isilon has limitations on the number of files that can be generated."

More Dell PowerScale (Isilon) cons

"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."

"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."

"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."

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

"IBM Cloud storage is not cheap, but it could be."

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

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

More IBM Cloud Object Storage cons

Pricing and Cost Advice

"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."

"We used a reseller for the purchase."

"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."

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

"The price could be cheaper."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"The product is very expensive."

"I rate the tool's pricing a seven to eight out of ten."

More Pure Storage FlashBlade pricing and cost advice

"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 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."

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

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

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

"It is a really expensive solution."

"The solution's licensing cost varies based on capacity and performance requirements."

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."

More Dell PowerScale (Isilon) pricing and cost advice

"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."

"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."
