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.

More Pure Storage FlashBlade pros

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

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

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

Cons

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

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"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."

"I would like to see better integration."

"I would like to see the licensing fees improved as well as the price per terabytes."

"Its configuration should be easier."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

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

"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."

"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."

"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."

More IBM Cloud Object Storage cons

"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."

"Integration with other vendors is not available."

"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."

"Maybe it needs integration with HA."

"The biggest problem is that it is not able to provide block storage."

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"The solution's pricing could be better."

Pricing and Cost Advice

"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."

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

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"The product is very expensive."

"Our customers have seen a reduction in TCO."

"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."

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

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"The licensing is based on the number of terabytes."

"The solution is costly but reliable."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Cloud Object Storage is a web-scale platform that stores unstructured data - from petabyte to exabyte - with reliability, security, availability and disaster recovery without replication.

IBM

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.
