DataCore SANsymphony software-defined storage aims to deliver flexibility, scalability, and cost-efficiency in a HCI platform. Powered by a block-level storage virtualization technology, SANsymphony is designed to provide flexibility to control how data is stored, protected, and accessed. The vendor states users can ensure business continuity with just 2 nodes, easily scaling out to 64 nodes, and achieve productivity for performance-demanding workloads by improving I/O processing and reducing…

VMware vSAN is an enterprise-class storage virtualization software that provides a simple path to hyperconverged infrastructure (HCI) and multi cloud. VMware vSAN is no longer sold as a standalone product and is now available as a part of VMware Cloud Foundation.
This product is very well suited to companies that use SANs and wish to secure their data in another room on another physical medium, regardless of whether the SANs or servers come from different suppliers. It will work with all types of data storage and transport layers (FC or iSCSI). This solution is very economical for small infrastructures with all the functionalities of the leading manufacturers on the market.
vSAN is well suited for any application that can run in Virtual Environment. vSAN serves better for VDI, NSX, and vSphere on Cloud solutions. vSAN is a good fit for small and medium business companies. vSAN can't be a good solution where you have Oracle Solaris or IBM power systems. vSAN can't provide storage space using FCP protocol.
VMware runs VSAN certification programs to make sure the OEM sells validated nodes. It helps customers to select appropriate certified ready nodes like Lenovo ThinkAgile VX which comes factory configured and easy to set up.
Hyperconverged solutions reduce real estate space and networking costs when compare with shared storage. The host overhead also less.
Supports All-Flash (SATA and NVMe SSDs) and Hybrid vSAN with HDD and SSD. So customers can choose cost-effective solutions appropriate to their workloads.
Supports different storage policies, RAID and duplication, and compression features and it makes a complete storage solution.
There's very little that I can find in their software that I would say needs to be improved. Sometimes the updates are too frequent and just as we finish updating all our sites another update comes out. Due to the many, many various options for what hardware to use, sometimes it is difficult trying to figure out what hardware options are the best for the money. DataCore can help a bit with this but because they only are the software side of the solution they tend to not prefer one hardware vendor over another (they get along with everyone). They do have good documentation that covers known issues with various hardware items.
While they support de-dup, it is recommended that you not de-dup the storage used for operating systems, or high change rated type data. The requires some planning to ensure the storage that is targeted for de-dup only have data that end users would be using (such as MS Office files etc.). Also, their de-dup console is not yet integrated inside their main SANsymphony console. They are working on it but it's not there yet.
While their console allows you to connect to each of the nodes without closing the interface you have to log out and in when you switch between a different storage server groups. It would be nice if they had an interface more like vCenter to where you see all server group in a list and can just click on each group. It would be nice to be able to see multiple groups at the same time. So having more of an Enterprise approach (v/s a local storage cluster) view would provide better management of the environment. For example, their current reports can only run for each storage server group. There is currently not a way to run the same reports or look at performance across the enterprise (only the local site).
Having an enterprise "Storage Dashboard" that could show capacity, usage, performance and any issues would also be very beneficial. Currently, DataCore does not have this.
It would be nice to have fabric-based storage acceptance to disaggregate storage and expand beyond the node concept. The assumption that increased storage needs require increased compute or ram is simply not true.
The licensing costs are high but you do get what you pay for.
Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.
In the 3 years I have been running this, I have contacted support around 4 or 5 times and that was for minor questions with exception of one time when I was performing an update on the system. And in that one time, they were very timely in assisting me with correcting the problem. Top notch customer support!
Support is (as always forVMware) top notch and easy to work with. The majority of computer companies are outsourcing their tech staff, and it seems they do as well. But their guys know the product well and are quick to respond to your ticket (if the severity is right!).
We reviewed DotHill, EMC, HP, Dell-Compliant, Left-Hand, NetApp and VMware's vSAN offerings and after reviewing costs, performance, and features, DataCore came out on top. We discovered that DataCore's solution allowed us to save about 50%, as compared to other SAN vendors but maintained a rich set of features that we needed for current and future growth.
VMWare stand out compared to all the products. However, it is worthwhile mentioning the following products can be used to achive similar results. Hitachi Virtual Storage Systems Nutanix Cloud Infrastrucure. In case if we are using Nuatinux at the Hypervisor level then it would be recommended to use their very own product for storage virtulization even though the vendors say that all their products are cross platform supportable. However, during tests we have found high performance when using same products accross virtualization.
The ROI for VMware vSAN seems very positive. We have yet to need to upgrade since we put it in a few years ago, but without the heavy cost of dedicated storage, we have already seen reduced hardware maintenance costs and reduced management time spent.
With the cost of dedicated storage and its separate maintenance costs, all this is rolled back into the hosts. The hosts cost more with drives in them, but not near as much as the separate dedicated storage did.
Before VMware vSAN, you had hosts and storage devices aging out, running out of capacity, or underperforming. With vSAN you only have to worry about the hosts.
