Featured Reviews

Eric Black - PeerSpot reviewer
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.
Amarnath Charugundla - PeerSpot reviewer
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.
Rifat Rahman - PeerSpot reviewer
Offers reliable performance and availability for large deployments
I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

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

Pros

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The most valuable features are the Metro clustering, and disaster recovery."
"Speed and ease of use are the two most valuable features."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"The most valuable features of this solution are the rewrite speed and the nonstop services."
"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."
"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"On a scale of one to ten, I rate this solution a seven."
"I appreciate its storage licensing model, as it offers flexibility."
"The capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."
"The most valuable feature is the easy interface."
"The customer service executives of all Nutanix products are active and responsive."
"I would recommend Nutanix Unified Storage. It's easy to use, and they are the best when it comes to storage services."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"The solution's most valuable feature is the Prism Central centralized management console."
"I like the distributed and self-healing nature of the product."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"The community support is very good."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"Without any extra costs, I was able to provide a redundant environment."
"The configuration of the solution and the user interface are both quite good."
"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."
"Ceph has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack."
 

Cons

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."
"The solution is expensive."
"I want efficiency. FlashBlade doesn't have efficiency now."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."
"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."
"Its configuration should be easier."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"The product does not offer one console."
"The licensing terms are restrictive, as they go by terabyte cost."
"There are some techniques that need to be improved because sometimes, during processes, it gets stuck on the console, requiring command line interventions, indicating gaps between the GUI and command lines."
"It is challenging to configure access control settings."
"The interface could be improved."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"We have issues with software updates occasionally."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."
"If you use for any other solution like other Kubernetes solutions, it's not very suitable."
"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."
"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."
"It would be nice to have a notification feature whenever an important action is completed."
"The licensing cost is excessively high. This is a significant issue from my perspective."
 

Pricing and Cost Advice

"Our licensing is renewed annually."
"The price of this solution could be made more affordable."
"The price could be cheaper."
"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 pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"The pricing for FlashBlade is between cheap and moderate."
"I feel that the price could always be lowered."
"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."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"The pricing is a bit too high."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
"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."
"The solution's pricing is better compared to other products."
"It is very good. It is much more competitive than a dedicated storage platform."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"We never used the paid support."
"The price of this product isn't high."
"The operational overhead is higher compared to Azure because we own the hardware."
"There is no cost for software."
"I rate the product’s pricing an eight out of ten."
"The price of Red Hat Ceph Storage is reasonable."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
