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.

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 is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

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

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"Speed and ease of use are the two most valuable features."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

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

"The solution provides many controllers."

More Pure Storage FlashBlade pros

"The main positive impact that Microsoft Storage Spaces Direct has had on my company over the years is increasing performance; our checks show it is three times faster than VMware, making us extremely happy and motivated to keep using it."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The initial setup is straightforward."

"The performance, reliability, and affordability has been most valuable."

"Its technical support is excellent."

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The most valuable feature are the caching capabilities using the storage class memory."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

More Microsoft Storage Spaces Direct pros

"The most valuable feature is that it is software-defined storage. Also, being able to do maintenance on the fly is a real benefit: migrating off, updating, and then moving the guest back on to the nodes."

"The most valuable features for us are the ability to scale out the nodes independently, and the flexibility of the nodes. We can put almost any type of server in there with our connectivity and everything works great."

"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."

"VMware vSAN has greatly reduced refresh spending."

"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."

"It's completely hyper-converged, so it's very convenient."

"The most valuable features are productivity and data storage."

"The most valuable feature is fhe flexibility, the ability to move the machines around without hesitation."

More VMware vSAN pros

Cons

"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."

"I would like to see better integration."

"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."

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

"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."

"The documentational aspect of FlashBlade needs improvement."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"Microsoft closed the shared cluster support, which is important for the solution."

"Documentation management could be improved"

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"I think the online documentation needs a lot of work and so do the sizing tools."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"There is a lot of room for improvement. I would like to have more tools to monitor the function and problems."

"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."

"Microsoft closed the shared cluster support, which is important for the solution."

More Microsoft Storage Spaces Direct cons

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

"We often run out of space but we have enough capacity for memory and CPU. It's difficult to find the balance between storage and memory CPU."

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

"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."

"If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much."

"Its integration with a hybrid cloud can be improved. Its scalability can also be improved so that it can be integrated with more than 32 nodes. The maximum number of nodes is okay, but our use cases could probably do with more nodes, probably up to 64. In terms of new features, it should probably have the basic support for high-speed networking spaces."

"I would like a better Hardware Certification List (HCL). The HCL should a little easier to deal with."

"I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in."

Pricing and Cost Advice

"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."

"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."

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

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"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 could be cheaper."

"Our licensing is renewed annually."

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

More Pure Storage FlashBlade pricing and cost advice

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"Cost-wise the product is one of the more affordable within the category of products."

"The solution is expensive."

"The product’s pricing is a bit higher than other solutions."

"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."

"This is a cost-effective product. It's a bit cheaper than the other solutions."

"I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee."

"In comparison with other solutions, such as HP or Cisco, I find the solution to be quite pricey."

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

"Users may also start off with the demo version of the tool. After you learn to use the solution, you can buy it if it is beneficial."

"The vSAN is somewhat expensive to license."

MS Storage Spaces Direct

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

Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.

Microsoft

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."
