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.

Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

Steve Qualls

Senior Storage Engineer at Q & Q IT Consulting

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.

Quotes from Members

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

Pros

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

"The most valuable features are the Metro clustering, and disaster recovery."

"Speed and ease of use are the two most valuable features."

"The most valuable feature is Safe Mode."

"The most valuable feature of this solution is performance."

"We have seen a reduction in the total cost of ownership by around 20%."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"The initial setup is pretty quick."

More Pure Storage FlashBlade pros

"On a scale of one to ten, I would rate Amazon FSx a ten."

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"The shared storage capability is highly valuable."

"I rate the stability of Amazon FSx ten out of ten."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."

"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 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."

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

"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 Cloud Object Storage integrates well."

Cons

"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."

"They need better integration with public clouds along with a better hybrid solution."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"The solution is expensive."

"There could be improvements in public cloud integration."

"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."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

More Pure Storage FlashBlade cons

"A direct FTP feature would be beneficial instead of relying on transmission services."

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

"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."

"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."

"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."

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

"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."

More IBM Cloud Object Storage cons

Pricing and Cost Advice

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

"The product is very expensive."

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

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

"Our licensing is renewed annually."

"I understand that it is competitively priced compared to other brands."

"We used a reseller for the purchase."

More Pure Storage FlashBlade pricing and cost advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."

"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."

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

"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."
