Eric Black

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.

Yves Sandfort

CEO & Majority Shareholder at Comdivision Consulting GmbH

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.

Quotes from Members

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

Pros

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"It is very easy to use, and it is very fast."

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

"The solution provides many controllers."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The main feature I have found to be product replication."

"The initial setup is pretty easy and simple."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

More Pure Storage FlashBlade pros

"I like that it can virtualize more than three hundred storage providers."

"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."

"IBM offers excellent customer service."

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

"We are happy with the support that IBM provides us."

More IBM Spectrum Virtualize pros

"Technical support has been fantastic. We always get answers quickly whenever we call."

"Stretched Cluster is one of the big features that we use across multiple data centers."

"All the features are working great."

"Stability-wise, I rate the solution a ten out of ten."

"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."

"Overall the solution is very good."

"The product is highly scalable and significantly supports our organization's needs."

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

More VMware vSAN pros

Cons

"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."

"The feature that we're waiting on is better integration with the cell services."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

"I would like to see more monitoring capability included in the next release of this solution."

"Its configuration should be easier."

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

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"The Storwize port is not so stable."

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

"The disk reliability is not that good."

"For improvement considerations, I would probably say multiple sites."

"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."

"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."

"Tighter integration with cloud storage might be useful as a target for a variety of use cases."

"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."

More IBM Spectrum Virtualize cons

"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."

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

"The server files are larger than before."

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

"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."

"I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment."

"VMware vSAN could improve by having better integration with other vendors and the storage is limited, I prefer it to the traditional storage."

"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

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

"The product is very expensive."

"The price could be cheaper."

"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."

"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 pricing for FlashBlade is between cheap and moderate."

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

More Pure Storage FlashBlade pricing and cost advice

"The entry point of pricing for this product is the most amazing price ever in the industry."

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

"It has a lot of advanced functions for a reasonable price."

"We would like the CPU cycle to save more on the licensing costs for us."

"Do a proof of concept, if you are not comfortable jumping in, but do it."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"I think it is a good value for the price."

More IBM Spectrum Virtualize pricing and cost advice

"We have increased our user productivity."

"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."

"The cost is expensive. I purchased two servers. The hardware cost was $19,000. The software cost for these two servers, including the vSAN, was $30,000, which is $11,000 more than the hardware. Then I had to pay another $5,000 for installation and implementation for professional services. In total, it was $54,000 for two vSAN Servers."

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

"From a cost perspective, it is expensive. From a usability perspective, it reduces the overhead costs attached to its users' servers."

"Due to recent changes in VMware's licensing approach by Broadcom, the cost has increased significantly, making it less attractive from a cost perspective."

"It could be cheaper."

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

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 Virtualize is a dependable solution that improves data value, security, and simplicity for new and existing storage infrastructure. Proven over 12 years in thousands of deployments, its innovative virtualization capabilities help organizations achieve better data economics by supporting new workloads that are critical to their success. IBM Spectrum Virtualize software helps make new and existing storage more effective and standardizes functions traditionally deployed separately in disk systems for greater flexibility and potentially lower costs.

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."
