All in all this series great in addressing issues applications that need flash storage as a backend storage supply. It addresses the need for fast, responsive servers that need to boot quickly. It is easy to use and for the most part there are few issues and none that can't be addressed/fixed quickly.

The product is a must for enterprise & SMB segments as this gives a good value for money and the licensing policy is very well defined and cost effective for the feature set it provides. This is very well suited for organization which have multiple brand storage systems and would like to consolidate them all together, thus providing a huge storage capacity for the organizations data growth. The product becomes less appropriate in organization where they have single storage platform as the service provider would have the ability to consilidate all the storage systems. Hence this products may be under utilized.

Pros
Dell Technologies
  • Dell Compellent support (Co-Pilot) and the add-on service (Optimize) are critical services that Dell Compellent does very well. Alerts from the array are sent to Co-Pilot where tickets are automatically generated and customers are notified of events. Of greater importance at times is the proactive support Co-Pilot and Optimize provide by contacting us of inefficiencies in the array and consulting on resolutions.
  • Enterprise Manager (Dell's "single pane of glass" management framework) is a useful tool for configuration/evaluation of the array and other Compellent products.
  • Ease of management. From firmware upgrades to managing server volumes the process is much simpler than with other arrays.

  • 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.

Cons
Dell Technologies
  • The GUI could be a little more updated with a lot more information regarding usage.
  • There could be some assistance with high I/O times where snapshots go to consolidate. There seems to be issues when that attempts to occur, and there will times where the virtual machine stuns due to the I/O intensity.
  • Modification of multiple volumes or the creation of multiple volumes is a pain in the DSM management console.

  • We were a fairly early adopter of VMware vSAN and as such experienced several growing pains.
  • We experienced a few bugs that took a few software versions upgrades to go mostly away.
  • The biggest issue we had overall was with host drivers. Even with vSAN ready node compatible hosts, you have to be very careful that the drivers for NIC and RAID controllers are right.

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.

Support Rating
Dell Technologies
This is not solely based on the support engineers themselves but more so that the logging and gotcha's that their array has. There have been multiple times where logs are pulled, but the folder is not large enough, and it crashes the array. Other times there are certain aspects that support either does not know of or isn't knowledgable about how to look at particular issues that could be causing problems.

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!).

Alternatives Considered

We selected Compellent solely based on price. Honestly I would rate it only slightly better than a QNAP we used (which was even cheaper). If performance and reliability are factors in your decision (and they should be) I would recommend looking at something like a VNXe.

Our VMware solution is built in-house for the organization's private application, we don't want to put our data on cloud premises. Also, vSAN is a cost-effective solution for our environment. We have done the POC with both products to understand the Flexibility, Management, and cost. After the successful POC, we have chosen the VMware vSAN.
