Quotes From Members

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

Pros
"A typical system administrator with minimal experience in Hyper-V, VMware, or Windows can do VSAN configuration and maintain VSAN operations.""The management interface on the software is very simple. It is insanely simple compared to most SANs. The interface is also powerful when used to complete tasks that an IT administrator needs to complete.""The vSAN provides full redundancy for storage while reclaiming some rack space.""StarWind Virtual SAN for vSphere is a software-defined storage solution that has reduced administration time for storage. It's pretty straightforward to install and setup it and so far it has been robust and worked as advertised from StarWind.""It allows me to configure High Availability and failover clustering with some fault tolerance, at a cost point that doesn’t break the bank for a small business budget.""This solution enables us to make better cost-effective use of our existing hardware and leverage the current infrastructure at a higher level than we could before.""VSAN works great; it's very easy to install, configure, and manage.""We have experienced multiple hardware failures at one site and the fault-tolerant volume worked exactly as expected with zero downtime."

"It's easy to use and has a very smooth onboarding process.""One of the most valuable features is that it can be applied at any scale.""It is all-in-one. The compute processing, storage, and network altogether make it convenient. We don't have to have different modules for expansion.""In general, being able to patch and not having to pay for SanDisk is the best thing about hyper-converged.""There are a lot of features in Nutanix that are different from other hyper-converged solutions, such as site-to-site replication. VM-based site-to-site replication is bundled with the software licensing. For the DR, it has the availability groups, which is one of the key features that Nutanix provides.""Performing a Nutanix software upgrade is a very simple and non-disruptive process.""The most valuable features are simple management and one-click upgrades.""In terms of scalability, adding a number of nodes, I find that it will not be any issues."

"The all-flash disc is the most valuable feature of this solution.""The mobile app is very helpful.""The technical support is very good.""Pure Storage is extremely reliable — it's never failed.""Technical support has been amazing.""This solution is very scalable.""We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent.""The solution offers amazing performance."

Cons
"The main thing I would like to see improved is the level of documentation.""I would like to see options for automated notifications of any changes, including, for example, synchronization issues.""I found that certain browsers are not fully compatible with the administration web access portal.""The main issue we ran into was the documentation. We attempted to set up the product in our test environment by ourselves and ran into several areas of the documentation that were unclear to us.""The console is something that I feel could be improved. There is nothing technically wrong with it, but it can be jazzed up and/or made to be a little more intuitive.""If there was one thing we could request, it would be the ability to shrink volumes. For example, we want to be able to decrease in the size of the volume.""StarWind relies on the underlying OS to manage the "SAN files" whether that would be a RAID volume, software RAID (such as LVM), etc. It would be useful if StarWind could incorporate the actual physical drive management inside of the solution, similar to Storage Spaces Direct.""In the next release, they could make some graphs of the real-time loading, speed of storage, and interfaces. Of course, these can be viewed in other places. But, in the event of a malfunction or troubleshooting, this would be convenient."

More StarWind Virtual SAN Cons »

"Nutanix Acropolis AOS could improve by adding some NAS features, similar to the ones that are available in the NetApp solution.""USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix.""Nutanix needs to improve network features like Passthrough – SR-IOV. It could be improved by supporting SR-IOV, if they had that support, I would not have needed to implement the VMWare vSAN.""The only problem is that not many operating systems are supported on the AOS hypervisor. They need to probably increase the support on multiple operating systems. As of now, a very limited number of operating systems and patch levels are supported on AOS.""I'm sure there are a lot of things that could be improved, but I'm actually very satisfied with this product. There may be some possibilities to move the virtual server dismounting points or to move the server from one group to another, but I can't think of any special improvements or update features.""I would like to see official compatibility with Red Hat in the future.""In the future, I would like to see integration with external storage using the fiber channel""I think some of the tasks that must be done using CLI could be added to the web interface."

More Nutanix Acropolis AOS Cons »

"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile.""The integration capabilities could be improved.""When we were doing some tests, we found that there was an I/O freeze when they were switching the controller.""I can't see where they can make anything better, unless, of course, they lower their prices even more.""FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool.""Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable.""I feel like there is too much automation; the user doesn't have any manual input.""The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."

Pricing and Cost Advice
"This is the best priced solution for an SMB.""I think the bang for the buck is much better with StarWind Virtual SAN.""The cost takes into account the number of nodes, so the size of the storage is not important.""The StarWind VSAN business model is very cost-effective.""The setup cost, pricing, and licensing are very straightforward. They are exactly what you expect.""If you are looking at a traditional SAN for a small cluster, give StarWind vSAN because you will save thousands without any compromise.""The cost seems a bit steep, and I wish it was less expensive.""Licensing is easy and the whole package is cost-effective."

More StarWind Virtual SAN Pricing and Cost Advice »

"This product is less expensive than some of the competing HCI solutions.""When compared to the competitors, the price is reasonable.""My advice is to get the ultimate license, as it is worth it.""The licensing costs are a bit expensive but when you compare the features, it's reasonable.""Nutanix is cheaper than Cisco HyperFlex, although it depends on the configuration because Nutanix can also be expensive.""Our Nutanix license is for five years. There is a support arrangement there, but that aspect is more or less taken care of during the initial installation. With HCI architecture, whenever we do any kind of auto scaling or scaling of servers and resources, there is a significant amount of software licensing involved.""The cost of Nutanix Acropolis AOS is reasonable.""The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."

More Nutanix Acropolis AOS Pricing and Cost Advice »

"There is an annual or perpetual license required for this solution.""They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good.""I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC.""There are no fees for licensing. The hardware is paid for only once.""Its price is almost double than any other flash storage solution.""The pricing is reasonable.""We do not incur additional costs beyond the licensing fee.""When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."

Overview

For SMB, ROBO, Cloud and Hosting providers, who look to cut down virtualization expenses, our solution is StarWind VSAN. It is software that eliminates any need in physical shared storage by basically “mirroring” internal hard disks and flash between hypervisor servers. There is less hardware to buy in general, consequently less money is spent on purchase and maintenance. The existing hardware is used with maximum efficiency, so there is no money wasted at all.

StarWind Virtual SAN targets those who already have servers, or are bound to a particular vendor list to buy from. In case there is a new virtualization infrastructure to be built from scratch, StarWind offers a much better way – StarWind HyperConverged Appliance. It is a turnkey solution complete with hardware and software, powered by StarWind Virtual SAN. Those who need to build and maintain virtualization infrastructure at little to no expense, may be interested in StarWind Virtual SAN Free.
