We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"Supporting of Automated-Storage-Tiering (AST) is a good feature that saves money."
"During the maintenance periods, on any part of the storage or VMware migration, we have had no downtime."
"The ability to pool the storage to leverage thin-provisioning is a huge saving in space and costs."
"It provides high performance and business-critical storage."
"The interface is user-friendly."
"It's a software storage solution that can scale as we like. There is also has a parallel feature that enhances the performance of the storage solution. We can separate storage and computing, and we can scale these two parts of the platform to meet business needs efficiently."
"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."
"It uncoupled the idea of proprietary technology and component capabilities. It is basically a proprietary technology for a cost-effective infrastructure."
"The most valuable features are secure IOPs and LAN security."
"We are waiting for container support (on the roadmap), as well as a user-friendly full web-administration capability, and an improved API."
"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparing."
"Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial."
"I miss dedupe and decompression."
"I would like to see reporting added, such as a monthly connectivity report."
"Problem detection could be easier. It should help customers identify problems very quickly because it's not easy to analyze on the platform today."
"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."
"They can package it in a way that is specific to the hardware infrastructure and the hardware platform. It should stay fairly up to date with the drivers and the manufacturer issues. The problem with uncoupling the proprietary technology and component capabilities is that by uncoupling them, you run into some concerns or challenges over the poor performance model. These concerns really come when you start talking about high performance, high bandwidth, and high availability types of environments. While vSAN is a leader, in a critical view, it is not about being cost-effective. It is more about the immediate impact of money loss to the business in critical applications where we want to maintain a continuous operational 59 model. It is, however, good for QA/QC tasks. I don't necessarily know how it works in regards to VDI or virtual desktop infrastructure."
"The price can be reduced. Small businesses cannot afford this solution."
"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"Pricing has improved but it is still expensive."
"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."
"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."
"The price of vSAN could be lower."
"It is too expensive."
"It is expensive, but you get what you pay for."
