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.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

Enables efficient multi-environment cluster deployment and resource management with versatile features

While VMware vSAN is quite comprehensive, if we are running multiple infrastructures, applications, databases, and other elements, having a diagnostic tool to identify the actual problem area, whether application-side or infrastructure-side, would be beneficial. A proper monitoring tool that encompasses both applications and infrastructure would help in quickly resolving issues.

Quotes from Members

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

Pros

"The solution provides many controllers."

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

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

"The most valuable feature of this solution is performance."

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

"FlashBlade offers low latency, high throughput, and seamless scalability."

"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."

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

More Pure Storage FlashBlade pros

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

"vSAN provides default HA configurations, where if any host goes down, the VM moves around within the host. Even though the disks are local, the VMs moves around with the vSAN disk and vSAN provides a high availability on its own."

"The ability to have a disaster recovery option for our end-users by being able to use VDI and the vSANs, and the ability to do replication across multiple data centers, are valuable to us."

"The deduplication and compression are excellent."

"The features of vSAN allow us to reduce our operational complexity to a large degree."

"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."

"IOPS is comparatively best to run VDI solution."

"Allows us to implement more quickly, and to ease the maintenance."

"Storage is expandable with no extra cost."

More VMware vSAN pros

Cons

"The solution is expensive."

"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."

"The speed could be improved."

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

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

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

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

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

More Pure Storage FlashBlade cons

"he interface is not user-friendly so the ease of use could be improved."

"The reporting mechanisms need improvement."

"Lacks an integrated backup solution."

"The customer service is good but there is a cost for it. It does not come free."

"They should provide Deduplication and Compression over the hybrid drives."

"vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline."

"The main problem we had was hardware compatibility, finding the right hardware that was certified."

"I think it needs to be more cost-effective. I would also say that even though the capacity is good, there is also room for improvement there. Also, they could improve the security of the system."

"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."

"It would be much improved if we could somehow integrate a better backup with it. Right now, we're using Veeam and it's okay, but I would like more of a VDP vSAN solution. That would be excellent. The VDP, at least the last time we looked at, it was just not quite there."

More VMware vSAN cons

Pricing and Cost Advice

"Licensing fees are paid yearly."

"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."

"Our customers have seen a reduction in TCO."

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

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

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

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

"Our licensing is renewed annually."

More Pure Storage FlashBlade pricing and cost advice

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"If you are cost-sensitive then this solution is not for you."

"The price of vSAN could be lower."

"The product's price is not high. The tool is available at a normal price."

"The cost of VMware vSAN is reasonable."

"We have increased our user productivity."

"The licensing cost is high and should be taken into account."

"We pay a yearly licensing fee."

"It is not that expensive, and it is not even cheap. If it is designed in a proper way, it has good pricing, but if you do oversizing, the price will be high. There are different licensing models."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

vSAN

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 Accelerate is a software-defined block storage solution designed for rapid deployment across heterogeneous infrastructure for hybrid cloud and delivering consistent service levels to a dynamic workload mix. It is based on proven grid-architecture, enterprise-scale IBM XIV technology. IBM Spectrum Accelerate can be deployed, including as hyper-converged infrastructure, on any x86 server, on pre-installed third-party appliances or on public cloud infrastructure, and is available as a service on IBM Cloud infrastructure.

IBM

VMware vSAN is a software-defined storage product that is used in collaboration with VMware ESXi hypervisor and that provisions and manages storage based on policies, regardless of the underlying hardware. The solution enables you to prime your business for growth through its seamless evolution (it is integrated with vSphere and requires no new tools), its flexibility, and its multi-cloud capabilities. As an industry-leading software, VMware vSAN provides high levels of performance with minimal impact on CPU and memory.

VMware vSAN Features

VMware vSAN has many valuable key features. Some of the most useful ones include:

Storage policy-based management (SPBM): VMware vSAN supports storage policy-based management for automated management of storage profiles.

Software-defined data-at-rest encryption: With this VMware vSAN feature, you can prevent unauthorized access of data at rest.

Multiple nodes: VMware vSAN provides clusters that can include as few as 2 nodes or as many as 64 nodes.

High security and availability: VMware vSAN offers stretched clusters, allowing more than one virtualization host server to be used in the same setup, promoting higher security as well as availability.

Deduplication: VMware vSAN’s deduplication compresses data to ensure efficient storage management and security.

HCI mesh updates: VMware vSAN clusters can share storage capacity with non-HCI Sphere clusters and can adopt HCI without having to scale computing resources and storage or replace existing servers.

Simplified file services: With VMware vSAN’s file services, backup of file shares is simplified. You can use APIs that allow backup and recovery software vendors to integrate with your VMware vSAN file services, which enables backup software to track new data and add scalability enhancements to files.

VMware vSAN Benefits

There are many benefits to implementing VMware vSAN. Some of the biggest advantages the solution offers include:

Reduced total cost of ownership (TCO): VMware vSAN helps you reduce upfront costs for businesses because it can be easily deployed on inexpensive x86 servers. In addition, its highly scalable infrastructure and quick deployment also save organizations time and money, making it an efficient storage solution.

Good manageability: VMWare vSAN is easy to set up, manage, and provision, without sacrificing performance.

Scalability: VMware vSAN is agile and allows administrators to scale storage on demand, quickly, and efficiently via policies and rules.

Simplicity: VMWare vSAN is simple to configure since it is embedded in the vSphere hypervisor. Installing it using the vSphere Web Client can be done quickly.

Reduced risk: VMWare vSAN reduces the risk associated with digital transformations by utilizing existing tools, skill sets, and solutions.

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the VMware vSAN solution.

PeerSpot user Yves S., CEO, Cloud Evangelist at Comdivision Consulting GmbH, says, “vSAN gives us a lot of advantages when we need to expand resources. We have an overall larger host infrastructure, and we split that up for specific customer test and use cases. In that specific scenario, we can easily add more hosts or reduce the number of hosts in the environment.”

A reviewer who works in Infrastructure Security explains, “The ease of use is great. The initial setup and upgrade process was pretty straightforward. And, technical support is great.”

Laurent N., Director at Softlogic, comments, "The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
