Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Offers the ease with which you can move data between on-premises storage and the cloud and then retrieve it back on-premises when necessary

IBM Cloud Object Storage supports big data and analytics workflows. However, I usually have to refer to my documentation for that. Cloud environments are part of almost every project I've been involved in over the last few years, but I rely heavily on documentation whenever I need to do anything in the cloud. I know the basics, but the technical details always need refreshing. I create the drawings or diagrams of how the on-premises and cloud environments interact. So, visual representations are helpful. I'll diagram the on-premises environment, the cloud environment, and any appliances in between and then work from there. The integration capabilities simplified our data workflows. Like, the integration itself is pretty easy. The access appliances create the connection between both environments.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

Quotes from Members

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

Pros

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

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

"It performs well and it is also very fast."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"It is very easy to use, and it is very fast."

"The product is scalable and easy to expand."

More Pure Storage FlashBlade pros

"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."

"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."

"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."

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

"IBM Cloud Object Storage integrates well."

"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

Cons

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"The features provided for SMB customers are limited."

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

"The solution is expensive."

"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."

"I want efficiency. FlashBlade doesn't have efficiency now."

More Pure Storage FlashBlade cons

"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."

"IBM has limited cloud storage."

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

"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."

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

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

"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."

More IBM Cloud Object Storage cons

"he interface is not user-friendly so the ease of use could be improved."

"The reporting mechanisms need improvement."

Pricing and Cost Advice

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

"The price is a little high."

"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."

"The price of this solution could be made more affordable."

"We used a reseller for the purchase."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"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 price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"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."

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"If you are cost-sensitive then this solution is not for you."
