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.

Quotes from Members

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

Pros

"It uses the same platform for connectivity so integration is seamless."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"It's very easy-to-use."

"The onboarding and integrated monitoring tools are pretty good."

More Pure Storage FlashBlade pros

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

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

"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."

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

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

"IBM Cloud Object Storage integrates well."

"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."

"It is more stable and scalable compared to the Windows file server."

"They have well-documented best practices and the interface is good."

"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."

"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."

"The management interface is great and you have handy access to several details about your file shares."

"For somebody like me who grew up building what others call three-tier and I call traditional architecture, the valuable thing is that you can now buy it. You can have new deployments and infrastructure up and running with very little infrastructure behind it."

"It is very scalable."

"The interface is quite simple. It is very good. It is easy to configure. It also has a powerful CLI."

Cons

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"The feature that we're waiting on is better integration with the cell services."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"I would like to see more monitoring capability included in the next release of this solution."

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

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

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

"I would like to see better integration."

More Pure Storage FlashBlade cons

"IBM has limited cloud storage."

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

"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."

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

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

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

"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

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

"Nutanix could improve the ability to track user actions, such as identifying who deleted a folder."

"When it comes to Nutanix Files, one thing that would be great is a slightly easier way of managing snapshots and restore points, especially when a third party is involved."

"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."

"The escalation process with technical support could do with some improvement."

"The solution should keep adding new features to be competitive in the market."

"The dashboard can have more details and be more useful."

"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"Our licensing is renewed annually."

"Licensing fees are paid yearly."

"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."

"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."

"Our customers have seen a reduction in TCO."

"The price could be cheaper."

"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."

"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."

"Pricing is not cheap."

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

"The pricing is fair."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"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."

"In my opinion, the product is fairly priced."

"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's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."

"I'm happy with the cost and licensing because I don't have big volumes."
