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 most valuable features of this solution are the rewrite speed and the nonstop services."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

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

"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."

"The most valuable features are the Metro clustering, and disaster recovery."

"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 performs well and it is also very fast."

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

More Pure Storage FlashBlade pros

"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."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable features."

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

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

"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."

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

"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

More IBM Spectrum Virtualize pros

"The solutions best feature is that it is easy to use."

"The scalability of the solution is most valuable."

"Its ease of use is most valuable. It is easy to configure, and there is a unified interface, which makes things slightly easier."

"vSAN can help customers save on storage system costs, and also save on the human cost."

"We find it easy to deliver this solution."

"Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware."

"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."

"The product’s most valuable features are performance and expandability."

More VMware vSAN pros

Cons

"Its configuration should be easier."

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

"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."

"The solution is expensive."

"I have not seen ROI."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

"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."

More Pure Storage FlashBlade cons

"The disk reliability is not that good."

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

"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."

"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."

"The training program could be improved."

"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."

"Adding features for data deduplication is one area of improvement."

"GUI should be developed in HTML5 as opposed to Java."

More IBM Spectrum Virtualize cons

"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."

"The updating process could be easier."

"It is an expensive solution."

"The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition."

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

"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."

"There is a room for improvement on the latest version of compatibility with the VMware product, especially for vSAN and with other vendors on their motherboards and driver configurations."

"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."

More VMware vSAN cons

Pricing and Cost Advice

"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."

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

"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."

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

"The pricing for FlashBlade is between cheap and moderate."

"The product is very expensive."

"I rate the tool's pricing a seven to eight out of ten."

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

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

"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."

"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."

"This solution came as an additional cost for the TSM package we chose."

"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."

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

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

More IBM Spectrum Virtualize pricing and cost advice

"The vSAN is somewhat expensive to license."

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

"Enterprise customers can customize their licenses according to their own needs and budget."

"VMware vSAN is a little bit expensive and we pay annually. We have an educational institute where we receive discount prices from VMware. We do receive a reasonable discount but it's still expensive."

"The solution is relatively expensive compared to similar products."

"Its price could be improved."

"It is cheap. It is $0.02 a gig."

"I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license."

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."
