VMware vSAN is a versatile solution that users and customers have used to address various storage challenges. For instance, some users have migrated their SQL databases from all-flash storage vendors to vSAN, effectively solving issues related to SQL and storage licenses. Additionally, vSAN has been leveraged in production environments to run critical business services like ERP, VDI, HRM, EMAIL, Active Directory, DNS, and in-house applications. This demonstrates the product's ability to handle diverse workloads efficiently.

In terms of configuration flexibility, vSAN supports different kinds of raids such as 5, 6, and 10 for each VM service. Moreover, the vSAN configuration with 2xSSD and 4xSAS disks has proven to provide faster IOPS compared to iSCSI storage. This not only enhances performance but also helps reduce hardware and maintenance costs.

One highlight of vSAN is its ease of setup and integration with all VMware products. This seamless integration allows users to maximize their existing VMware infrastructure while benefiting from the unified storage pool created by vSAN. Furthermore, the compatibility with all-flash technology ensures that it can meet a wide range of workload requirements.

vSAN has been highly recommended for use cases such as testing performance on VMware clusters for Test/Dev departments and hyper-converged models used by SMB users. It also serves as the main hyper-converged infrastructure solution for housing production virtual servers and critical systems. Customers who prefer not to use external storage can leverage vSAN's ability to combine the storage of servers in a cluster, eliminating the need for a separate SAN and storage administrator.

Overall, vSAN provides a unified storage management solution for multiple storage devices from various vendors while delivering features like data deduplication and compression. Its usage spans across virtual desktops, cluster management, data warehouse support, VM, file, and backup storage across networks. With positive outcomes reported by users and a wide range of use cases, VMware vSAN proves to be a reliable, flexible, and cost-effective solution for storage challenges in various industries.

Flexibility and Data Accessibility: Users appreciated the ability to write data anywhere and access it anytime, even in the event of hardware failure. This feature provided them with flexibility and uninterrupted access to their data, contributing to a seamless user experience.

Simplified Management: Many users highlighted the ease of managing VMware vSAN from a single management platform, specifically mentioning vCenter. They found it convenient that VMware runs VSAN certification programs to ensure OEMs sell validated nodes, making it easier for customers to select appropriate certified ready nodes. This unified approach simplified infrastructure management and reduced complexity for users.

Difficult Disk Management: Some users have found it challenging to manage disks in the vSAN cluster, citing issues with finding unused/unassigned hard drives and balancing disk usage. They suggest a more user-friendly interface and guided configuration to simplify the process.

Limited Datastore Choice: Several reviewers express dissatisfaction with vSAN's limitation of having a single datastore for the entire cluster, which restricts their ability to isolate or group virtual machines as desired. This has been seen as a drawback by some users.

Compatibility Concerns: Many users mention compatibility issues with older servers and find it difficult to meet all hardware requirements. They believe that an expanded Hardware Compatibility List - HCL would be helpful in ensuring more compatibility and avoiding any potential complications during implementation.

Users of VMware vSAN have made several recommendations based on their experiences with the product. First, they suggest considering building your own VSANS (Ready Nodes) instead of using VXRails. This recommendation comes from users who have found that building their own VSANS allows for more customization and flexibility in their vSAN deployments. Second, users advise finding an easy algorithm to reduce CPU overhead and improve disk read and write cache. Some users have suggested that optimizing the CPU overhead and improving disk performance could enhance the overall efficiency of vSAN. Lastly, users recommend talking to support to confirm compatibility with the operating system requirements. They advise reaching out to support to ensure that vSAN is compatible with the specific operating system requirements of their environment. These recommendations provide valuable insights for users looking to make the most of VMware vSAN, allowing them to explore alternative deployment options, optimize performance, and ensure compatibility with their existing infrastructure.

We used vSAN to test performance on VMware clusters for our Test/Dev Department. It is handy technology that provides fast and easy access to virtual storage on a VMware farm. Due to the high load of our current SAN for the production environment, we decided to test this possibility and it showed good outcomes.
  • Provide management for computing and storage in one place.
  • Improved business agility.
  • Unify resources under policy based management
  • Improve security for data.
  • License politic from VMware.
  • Hard to meet all hardware compatibility on old servers hardware.
  • Balancing the disk usage in the vSAN cluster is sometimes hard.
vSAN is well suited for small/mid-sized business implementation to reduce the cost for VMware clusters. It is a big savings to the company on SAN storage. Nowadays, most companies are going to cloud so implementation of vSAN or SAN on-premises is not more required.
  • vSAN gave us the possibility to test HCI technology.
  • It is mostly positive impact because we've done our testing on time.
  • Good product for inexpensive storage.
vSAN was handy to do our testing. It helps to provide plenty of storage performance with a simple interface. It is easy to configure and works just great. VMware software, in general, provides the best performance and reliability for the virtualization platform. It's always worth trying HCI and testing modern technology.
VMware support is good. Really comfortable to use. Top educated VMware engineers solve any problems in 24x7 access.
Usability on a high level. The product provides a nice user-friendly interface. Monitoring and reporting are clear.

Our current license is the standard ( we previously had an advanced license). Managing an increasingly complex storage infrastructure with proper efficiency and costs is not an easy task, but vSAN has proven remarkably helpful in order to do that. In conjunction with vCenter and vSphere, it has reduced our complexity and costs greatly.

Our vSAN deployment is currently being used as the main infrastructure solution. We use vSAN for virtual desktops, cluster management, and data warehouse support. We use an SSD disk and HD per each ESXi, vSAN uses the SSD for the cache and the HD for data storage. What I especially appreciate is the data deduplication and compression and the raid 5 versus erasure coding, since it enables higher consolidation ratios, reducing costs. (Sadly this feature is only enabled starting at advanced licenses). It holds the majority of our production virtual servers, It really helps us to solve multiple problems such as data integrity, system stability, and has improved hyper-convergence for speeds and workloads.
  • Very strong data integrity.
  • The portability of the VMs.
  • Dataflow is great without a lot of tweaking.
  • The in-place encryption is a strong layer of security and it is great for establishing multi-tenancy trust.
  • Ease of use from vCenter.
  • Great data compression, lowering costs.
  • Expensive, but it's worth it since it actually reduces costs (in addition, whichever vSphere licenses you need).
It's not that good performance-wise and sadly the cost on each processor quickly scales up. However, it's great for scalability and data integrity, easy to deploy and configure. If you need more power, buy more nodes. It's great for small data centers but I wouldn't personally use it for big ones. vSAN is a good, yet expensive (because of the cost for each processor will quickly add up), option for hyper-converged storage.

The only thing I disliked is that data deduplication and compression and the raid 5 erasure coding are only for licenses equal or higher than advanced.
  • Even though the license prices were a huge investment, this has brought us better performance.
  • VM portability made testing faster.
  • Lower costs of ownership.
Support isn't that great compared to other VMware products and is kinda slow But, I didn't have any issues with it, other than response speed.
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.

We use vSAN in the College of Life Sciences at BYU. We have two VMware clusters with multiple hosts. vSAN allows us to utilize the storage of each host to create a virtual storage pool for our virtual machines. It has allowed us to eliminate our previous SAN and the administration that came with having a SAN. We no longer need a storage administrator.
  • It is built in vCenter so you don't need to run a virtual controller VM on each host.
  • Very easy to implement, it is just a matter of purchasing licenses and turning it on.
  • Simple to monitor within the vSphere console.
  • I have not found anything about VSAN that needs improvement. It does what it is supposed to do, and is easy to work with.
VMware vSAN is perfect in an environment where you have existing servers with storage and you would like to use them in a VMware environment. Also, for someone looking to build a VMware environment, they could purchase servers with storage and not have to worry about purchasing a separate SAN. vSAN would not be appropriate for someone who already has a SAN.
  • With vSAN, we no longer need a storage admin to run a SAN. And yet we still have all the functionality in vSphere including vMotion.
  • With vSAN, we no longer need a storage admin to run a SAN. And yet we still have all the functionality in vSphere including vMotion.
We used HPE SimpliVity in the past. HPE SimpliVity provided a similar functionality, but it required a virtual controller VM on each host which consumed CPU, RAM, and Storage. Upgrades and maintenance on the HPE SimpliVity nodes was more difficult because the controller VMs had to be shutdown separately because they could not be vMotioned to another host. vSAN is a far superior product.
I have not had the need to call VMware for support on vSAN, but they have always been very responsive and competent when it came to supporting vSphere issues we have had in the past.
vSAN is powerful and easy to use. I believe that is the best definition of usability. It was installed in minutes and we have not had a single issue.

We are using our VMware vSAN across the entire network for the majority of our VM, file, and backups storage at this time. Since all our user file shares live there, technically all our departments are using it too. We had many issues before with a physical SAN, but those are mostly a thing of the past.
  • Fastest SAN solution hands down.
  • Easy to connect hosts to LUNS/Datastores.
  • Great support staff and easy ticket system.
  • More direct integration with backup systems.
  • More user friendly interface.
  • Lower tier options for budget users would be nice.
VMware is widely known for their virtual server prowess and their vSAN implementation is just as good as their other products. It's easy to recommend this product to colleagues as everyone is using a SAN these days. I have already recommended this to others who are in the market for a new SAN or vSAN.
  • Positive impact: lots of time saved.
  • Positive impact: ease of use is through the roof.
  • Negative: We use it so much we need more space already!
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!).
The software side is where the magic happens, and VMware's vSAN works well and very few bugs encountered. If you run into an issue then support is usually quick to fix. Of course moving up versions you will see interface changes, some for the better, some worse. But that's to be expected in this business.
