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.

Unified management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

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."

"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."

"IBM Cloud Object Storage integrates well."

"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."

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

"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 scalability, data redundancy, and security are valuable."

"The deployment was very easy."

"The pricing, setup costs, and licensing of Nutanix Unified Storage (NUS) are amazing, in my view."

"The reliability and stability of Nutanix Unified Storage (NUS) is good, and the disaster recovery component is something impressive for this product."

"Unified Storage's centralized management features enable us to accomplish whatever we want in terms of operations and migrations."

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."

"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."

"The speed could be improved."

"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 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."

"Its configuration should be easier."

"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."

"I would also like to see better support for CIFS workloads."

More Pure Storage FlashBlade 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."

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

"IBM has limited cloud storage."

"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."

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

"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."

"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."

More IBM Cloud Object Storage cons

"I would like Nutanix to provide a solution for virtual disks. This is the main problem for which we want a solution."

"It's still pretty expensive."

"Requires higher upfront investment"

"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."

"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."

"Perhaps when it comes to deploying NUS virtual machines on top of CVMs, it should not be necessary for it to be in all of them or they should require fewer resources on the servers."

"Some of the new features in the tool cannot be used with just one click, as was possible in the past."

"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."

Pricing and Cost Advice

"The product is very expensive."

"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 is a little high."

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

"The price could be cheaper."

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

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

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."

"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."

"Pricing is not cheap."

"The pricing is a bit too high."

"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."

"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."

"It is very good. It is much more competitive than a dedicated storage platform."
