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.

Gives us a lot of advantages when we need to expand resources

Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier. Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more. Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

"The most valuable feature is that there is no single point of failure."

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

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

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

More Microsoft Storage Spaces Direct pros

"vSAN is one of the easiest implementations of any VMware product. It's almost like click it to enable it, then you're almost done."

"The most valuable feature is the fast performance."

"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."

"The deduplication and compression are excellent."

"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."

"Storage virtualization software with a good storage management feature. It's a scalable and stable software."

"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."

"It easily integrates with all types of storage."

More VMware vSAN pros

Cons

"There could be improvements in public cloud integration."

"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."

"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."

"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."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"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."

"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."

"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."

More Pure Storage FlashBlade cons

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

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

"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."

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

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

"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."

"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."

"Documentation management could be improved"

More Microsoft Storage Spaces Direct cons

"I'd like to see better integration with the Update Manager, with respect to firmware updates for hardware."

"Integration could be better."

"This solution would benefit from better collaboration with Cisco for driver updates."

"The solution functions as the marketing says, as long as you follow certain rules."

"We would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up."

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

"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."

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

Pricing and Cost Advice

"Our licensing is renewed annually."

"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."

"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."

"The price is a little high."

"The price could be cheaper."

"Licensing fees are paid yearly."

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

"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

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

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

"The solution is expensive."

"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."

"It could be cheaper."

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

"My customers have found VMware vSAN to be a little expensive."

"If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."

"The product's price has been increasing lately...VMware vSAN is expensive."

"Its price could be improved."

"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."
