VMware Developer Center Samples Exchange

At VMware Developer Center Samples Exchange, you will find “Sample Exchange”, a new portal built as an extension of VMware Developer Center which provides anyone the ability to browse, download, search, and contribute sample code that builds on VMware APIs. This document is a guide for those that wish to contribute samples on Sample Exchange.



Sample Exchange is not a repository that is hosting samples itself. Sample Exchange provides a catalog of samples that live in other repositories such as Github. Sample Exchange provides discoverability and a work flow around requesting samples as well as easy contribution of samples, but does no hosting itself.

SoftLayer local disk performance SATA/vSAN/SSD

SoftLayer local disk performance SATA/vSAN/SSD

What disk performance you can expect from local drives in Softlayer with VMware vSphere6, vSAN & local SATA or SSD drives?

This article is here to help you see and decide if performance will be enough for your needs.

I have 3 hosts with:

  • hardware Supermicro 2 CPU, 12 cores, 256 GB RAM,
  • hypervisor OS VMware vSphere 6 build 3073146,
  • virtual machine OS Windows Server 2012 R2.

I use CrystalDiskMark installed in Virtual Machine for testing disk performance.

VMware Disks types and testing examples:

  • 1 TB SATA in RAID1,
  • vSAN 800 GB SSD 2 TB SATA 4x on 3 hosts 20 TB datastore,
  • 800 GB SSD standalone.

Environment:

1 TB SATA in RAID1

The disk is used for VMware hypervizor boot, but we can use it to compare the performance with other options.

SATA_c2

vSAN 800 GB SSD + 2 TB SATA 4 drives, 20 TB datastore

Main storage location for most virtual machines 20 TB datastore, main VMware storage.

vSAN_c3

800 GB SSD standalone

In case that vSAN performance is not grating you the required IOPS throughput you can always switch to local SSD in standalone or RAID1 configuration, HA have to be used on application level. Or you can go for vSAN all flash.

SSD_c2

Summary

There is much more options in SoftLayer as to what choice of storage you have, but if you decided to go with local drives these are your options. Results are more or less expected, the worst is local SATA,  vSAN and standalone SSD always depend on type of application and how it uses the disk capabilities.

Use case

From troubleshooting point of view it is very good to have standalone SSD in one of your servers. In case an Application owner complains about speed you have options to use storage vMotion to your SSD and you can ask them: “Does it help?”. Usually not, but you did prove that storage is not the problem and will help you in bottleneck identification.
