Solutions Architect at Recovery Point Systems

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.

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.

"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."

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

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

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

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

"The flash ability, in terms of tiering and caching, is amazing"

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

More Microsoft Storage Spaces Direct pros

"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."

"One of the most valuable features of this solution is that it is stable."

"We didn't only choose vSAN; we chose VMware because of SR-IOV, which is more on the hypervisor level and not on the vSAN storage. It's part of the whole system."

"VMware vSAN is a global solution, so we can manage all the storage solutions in one place. It's embedded in VCI solutions."

"It is easy to work with, easy to handle, and easy to manage."

"When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes"

"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."

"I would suggest customers use VMware vSAN because VMware offers a stable solution with good hypervisors and the best features compared to other solutions."

Cons

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

"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."

"The speed could be improved."

"The features provided for SMB customers are limited."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"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."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"Documentation management could be improved"

"More optimization could be done in terms of mirroring."

"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."

"It is difficult to get a hardware compatibility certification for the solution."

"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."

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

"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."

More Microsoft Storage Spaces Direct cons

"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."

"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this."

"If the support could be provided more quickly, it would be very helpful."

"It can be very expensive."

"When we talk about improvements for vSAN, there is some way to go from a at least stability perspective. Adding all these new features is nice, but we are now at the level that most of the features you need in production are there."

"Troubleshooting tools could be improved."

"There could be more features with the automatic backup."

"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."

Pricing and Cost Advice

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

"Our licensing is renewed annually."

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

"Licensing fees are paid yearly."

"The price is a little high."

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

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

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."

"We have increased our user productivity."

"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."

"The cost of the solution is high and if it could be reduced the customers would be very happy."

"Cost-wise, the Nutanix licenses were cheaper, but in terms of the hardware, there was some contention around it. So, in terms of implementation, the way Nutanix was projecting the implementation on their end was that there were a lot of open-source admin platforms. vSAN is a licensed product in VMware, and Nutanix was proposing a KVM solution, which is open source. That's why their pricing was a bit cheaper, but when we were trying to compare it with an enterprise version of their management platform, it boiled down to the VMware vSAN being most effective in the long run."

"We pay a yearly licensing fee."

"The cost of VMware vSAN is reasonable."

"I'd love for this product to be cheaper."

"Every product is licensed with full support for a certain number of years. The licensing could be cheaper."

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."
