https://core.vmware.com/resource/vmware-vsan-design-guideWhen sizing a vSAN datastore, there are several factors that need to be considered to ensure optimal performance, availability, and scalability. Here are the explanations of the three factors to consider when sizing a vSAN datastore:
A. Storage Policy or Policies to be used: The storage policy or policies define the performance and availability characteristics of the virtual machines running on the vSAN datastore. When sizing a vSAN datastore, it's essential to consider the storage policies that will be used to ensure that the datastore meets the required performance and availability requirements. Different storage policies can have different resource requirements, such as CPU, memory, and storage, and these should be taken into account when sizing the vSAN datastore.
C. vSAN Slack Space: vSAN Slack Space is the amount of free space that vSAN reserves on each disk in the cluster to ensure that it can maintain optimal performance and availability. When sizing a vSAN datastore, it's essential to consider the vSAN Slack Space requirements to ensure that enough free space is available to maintain optimal performance and availability. The recommended amount of vSAN Slack Space is typically around 20-30% of the total capacity of the datastore.
F. Endurance level of capacity disk used: The endurance level of the capacity disks used in the vSAN datastore is an essential consideration when sizing the datastore. Endurance level refers to the amount of data that can be written to a disk over its lifespan. It's important to choose capacity disks that have a suitable endurance level to ensure that they can handle the expected workload of the virtual machines running on the vSAN datastore. The endurance level of capacity disks is typically measured in terms of Terabytes Written (TBW) or Drive Writes Per Day (DWPD).
In summary, when sizing a vSAN datastore, it's important to consider the storage policies to be used, vSAN Slack Space requirements, and the endurance level of the capacity disks used. These factors will help ensure optimal performance, availability, and scalability of the vSAN datastore.
