High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

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

Pros

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

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The main feature I have found to be product replication."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

More Pure Storage FlashBlade pros

"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."

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

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

"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."

"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."

"Nutanix Volumes is a perfectly stable product."

"DR and the replication power are valuable."

"The product's benefits stem from the ease of use and management it offers to its users."

"We migrated over to Nutanix and saw an immediate improvement in the performance."

"The inclusion of it in the Nutanix Objects Storage platform simplifies my process as I am no longer required to acquire a separate platform. Instead, I can simply purchase additional licenses as needed. All management can be performed from a single unified interface, making it a convenient and streamlined experience."

"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."

Cons

"Its configuration should be easier."

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

"I would like to see more deduplication."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

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

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

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

"It's on the expensive side, as expected for a niche product."

More Pure Storage FlashBlade cons

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

"IBM has limited cloud storage."

"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."

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

"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."

"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

"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."

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

"I haven't had any issues with the solution so far."

"There are still some gaps in the solution's synchronization that could be improved."

"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."

"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."

"The product does not offer one console."

"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"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."

"Our customers have seen a reduction in TCO."

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

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

"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."

"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."

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

"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees. We're not a Fortune 500 company, but we deal with Fortune 500 drug and energy companies. We have to play in that enterprise space if we're going to have enterprise customers. I'm very price-conscious, but I understand that if I want the best, I've got to pay the price."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."

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

"Nutanix is very competitive."

"The solution's pricing is better compared to other products."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
