MikaelHellström

IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Sales Manager at MSDSYSTEMS S.R.L.

Has simplified data protection across two locations and reduced time spent on recovery efforts

The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery. It is important because if we want to add a new code, it sets itself up from scratch, and if we want to add, for example, a 72 terabytes or petabytes node, we just drop it in, which is very easy. DataCore Swarm has positively impacted my organization through the support for my dedicated salespersons.

Amarnath Charugundla

System Engineer at Tata Consultancy

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

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

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

"It is very easy to use, and it is very fast."

"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."

"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."

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

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

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

More Pure Storage FlashBlade pros

"With DataCore Swarm, we have transitioned from tape-based backups, which were long, to Swarm, making the process more rapid and efficient."

"The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery."

"The ability for the solution to use any new hardware quickly and without administration is a great thing in the context of hosting."

"I find its flexibility valuable."

"The first feature is compatibility with the S3 protocol. DataCore SWARM allows you to quickly have an on-premise, robust and scalable environment that is natively compatible with the S3 protocol. The functionalities used are therefore derived from the S3 protocol, notably versioning and therefore the possibility of configuring immutability in governance or compliance mode. The object metada can be enriched with the addition of tags to subsequently enable filtering and searching. Configuring and using DataCore SWARM is simple and flexible. It is very easy to create domains, tenants and buckets for different use cases with various authentications. The cluster architecture also allows replication between different clusters at different configured levels (Cluster / Domains / ...) A web interface for browsing the content of existing buckets allows simple and rapid manipulation of certain objects such as sharing via a link or cropping a video. Finally, the physical architecture of the solution is based on an x86 server and its scale-up or scale-out evolution is very simple by adding disks or servers."

"DataCore Swarm is highly available."

"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."

"For customer service and technical support, I would rate them a nine out of ten."

"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."

"DR and the replication power are valuable."

"The scalability, ease of use, and technical support are the most valuable features of Nutanix Unified Storage."

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

"I rate Nutanix Unified Storage (NUS) nine point five to ten, as it's easy to manage, scalable, has great performance, and includes advanced features."

"Offers high performance, full control, and strong security for mission-critical workloads."

More Nutanix Unified Storage (NUS) pros

Cons

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

"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."

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

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"The features provided for SMB customers are limited."

"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."

"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."

"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."

More Pure Storage FlashBlade cons

"The main issue currently is the hard installation process."

"The product currently requires a significant number of servers to start. There are also network prerequisites to be met in order to guarantee good security of the architecture, which means that the product is only available to large customers. Besides, the license starts at 100TB. An Appliance version is being developed with an architecture based on containers which will make it possible to offer DataCore SWARM to everyone. The product has been evolving since the acquisition by DataCore, but maintaining and updating the product is not always easy and needs to be improved. For now, we only use DataCore SWARM for a few use cases and therefore a small part of the existing functionalities. With use we will perhaps have more criticism of the product but not for the moment!"

"The pricing can definitely be better."

"The solution needs simpler architecture."

"I would them to have more communication with other platforms, and it appears they are already doing that."

"The training programs could be improved. It's quite challenging to find adequate learning resources online, as there isn’t much available on the internet or YouTube."

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

"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp. It has snapshot, replication, high availability, and other data and storage-level replication, but there are some limitations."

"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."

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

"The dashboard could be more customizable"

"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."

Pricing and Cost Advice

"Licensing fees are paid yearly."

"We used a reseller for the purchase."

"The price is a little high."

"Our licensing is renewed annually."

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

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"The product is very expensive."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

More Pure Storage FlashBlade pricing and cost advice

"The first installation brick is expensive but the upgrades are extremely simple and granular by adding disks or nodes."

"You pay for what you use. For example, if you use one terabyte, you just pay for that one terabyte. But the pricing could always be better"

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

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

"The pricing is fair."

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

"The product is pricey."

"It is not too high for what we are using."

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

"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."
