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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies

IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool

Obasanjo Biliaminu

Head Systems Administration/Security at Nigeria Inter-Bank Settlement System PLC

From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.

More Nutanix Cloud Infrastructure (NCI) pros

Cons

"Its configuration should be easier."

"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."

"I would like to see better integration."

"I have not seen ROI."

"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."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

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

"Pure Storage FlashBlade should improve on more cloud integration."

More Pure Storage FlashBlade cons

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."

"Initially, stability was a concern as we encountered numerous issues and errors."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"There can be improvements in fault tolerance and making erasure coding faster."

More IBM Spectrum Scale cons

"They should support more VM, which is not currently supported."

"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant. The software-defined networking is quite limited, and we usually use other products to do that. We're aware that Nutanix is working on that and will be coming out with better solutions, and we can't wait because to do a fully software-defined architecture, the abstraction layer needs not only software-defined storage, which you have, but also the software-defined networking piece."

"The solution has more features than required"

"With some projects that we are deploying, there are errors that arise when adding nodes."

"This product would be improved if it included a hybrid cloud solution."

"They could improve the graphical user interface."

"As Nutanix Acropolis AOS is on the expensive side, one of its areas for improvement is the price. It would also be better if it can be integrated with other cloud providers, because currently, it's only for private cloud deployment."

"While the customer support is truly incredible, for Spanish speakers it would be appropriate to have support in their native language to further improve problem-solving conditions."

Pricing and Cost Advice

"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."

"I understand that it is competitively priced compared to other brands."

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

"Licensing fees are paid yearly."

"The price is a little high."

"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 product is very expensive."

More Pure Storage FlashBlade pricing and cost advice

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"The solution is costly but reliable."

"The licensing is based on the number of terabytes."

"Reconsidering the licensing packages could reduce the price, especially for companies that may not need all the bells and whistles. Many of the features are based on open-source software, so there's potential to offer more flexible pricing options. Additionally, with the right expertise, companies could potentially create similar environments themselves, reducing the need for extensive support and licensing costs. I rate its pricing a six out of ten. The tool costs around 300,000 dollars per year."

"Work close with your InfraTeam and discuss with Nutanix the best way to achieve sizing and price that are right for you."

"The pricing is quite good in comparison with HPE SimpliVity, Nutanix Scale, and even traditional architecture."

"I think it's cheaper than VMware in terms of cost."

"The setup cost, pricing, and licensing are very competitive and TCO is very low compared to three-tier solutions."

"Setup cost is minor, pricing is quite a bit (we have a 7-node-cluster for about 450K EUR with 2 vGPU-nodes for Citrix) but that includes hardware, software, and support."

"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."

"Our Nutanix license is for five years. There is a support arrangement there, but that aspect is more or less taken care of during the initial installation. With HCI architecture, whenever we do any kind of auto scaling or scaling of servers and resources, there is a significant amount of software licensing involved."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.
