Parallel file access efficiency and good file management with good scalability

We are using GPFS Scale for parallel file access. It's primarily for file management We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations. It's the only feature we are using since we have not explored other options. I wish there were some…

Expensive solution that requires professional services for installation and implementation

I'm still using a different solution. I only took two servers with vSAN to support one application that needs one feature that only VMware has. If not for that feature, I wouldn't touch VMware. Now, I'm looking at products like Nutanix, Silver Peak, Flexione, and FortiGate. For products that I choose, I don't need a specialist of that vendor. In VMware, I need a specialist in VMware. That's the issue I have with VMware. It's not like I can take any IT person, and they will know what to do. I need to make sure he will do the call, get the certificate and time to practice.

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

Pros

"We are using it for monitoring all of our storage."

"The profile share is a valuable feature."

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"It is a scalable solution."

"Its great servicing high availability. That is what it is used for."

"Allows us to share files across multiple environments."

More IBM Spectrum Scale pros

"It helped us survive power outages in one of our data centers, then continued to function without a hitch."

"The performance of VMware vSAN is very good."

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

"Allows us to implement more quickly, and to ease the maintenance."

"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."

"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."

"I like the tolerance of VMware vSAN."

"The performance has exceeded our expectations and exceeded our traditional converged infrastructure."

More VMware vSAN pros

Cons

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"The biggest problem is that it is not able to provide block storage."

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

"The solution's pricing could be better."

"I believe there is no graphic user interface, so they should include it."

More IBM Spectrum Scale cons

"This solution is not great for large file shares/object/rich media repository."

"Improvements can be made with respect to scalability."

"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."

"There is a lot that VMware could improve from a marketing perspective. The cloud is still new for many people, so extending storage should be effortless. It shouldn't be so complicated to extend the storage so workloads can access it no matter where they go."

"The product's complex setup phase is an area of concern where improvements are required."

"Lacks sufficient storage terabytes."

"The product can be improved in a couple of ways. One of those would be that they have a lot of hidden features, that are through the CLI, that would be great to have in the GUI, or just be more open about those features. It's something called RVC. It's a tool in the back end. It's a really great tool, but I had to find it through Reddit. So more information on stuff like that would be great. Also, in the user interface, giving us more features and more reporting that we can do from vSphere itself would be helpful."

"he list of hardware supported should be increased in the future."

More VMware vSAN cons

Pricing and Cost Advice

"The solution is costly but reliable."

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"It could be cheaper."

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

"The solution requires a license. The payment is on a yearly basis and It is not overly 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 licenses are very expensive. The renewal of licenses has extra costs attached to it."

"With vSAN, we didn't find the market that competitive."

"We did consider other hyperconverged solutions. It usually came down to price. vSan was the most cost effective thing."

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

Overview

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.

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."
