Quotes From Members

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

Pros
"GPFS monitoring is the best feature.""The most valuable feature is the ability to share files across different platforms.""We are using it for monitoring all of our storage.""The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."

More IBM Spectrum Scale Pros »

"As a function of our core business, it's a sought after tool that helps us provide analytical support across a wide spectrum of client needs. It's allowed us to test out in our connected restaurant - "TheWorks" - a fully-functional restaurant experience center that allows our clients to discover the value of our connected solutions firsthand. We deploy vSAN in this customer-like environment within a hyperconvergent infrastruction (HCI) to give our clients a better understanding and help optimize data and the end-users' experience.""The newer versions of this solution are much more stable and easier to manage.""VMware vSAN has greatly reduced refresh spending.""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.""We can also create test cases. We can even throttle down performance or release more performance. So, we can run more precise test scenarios.""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 is very easy to set up and very easy to use. It is very useful.""The deduplication and compression are excellent."

Cons
"The biggest problem is that it is not able to provide block storage.""The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers.""Integration with other vendors is not available.""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."

"I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up.""This solution would benefit from better collaboration with Cisco for driver updates.""This solution is not great for large file shares/object/rich media repository.""Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it.""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.""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 uncoupled even more.""If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much.""There's a lot that can be done to segregate. That may be available now in vSAN 7, I suppose, however, the deduplication and compression can be segregated."

Pricing and Cost Advice
"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."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface.""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.""It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components.""The price is expensive.""It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."

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 the industry-leading software powering Hyper-Converged Infrastructure solutions.
