Question

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster. The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs. The current vSAN cluster has the following configuration:

  • 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
  • 1 Disk Group per vSAN node
  • 1 x 400 GB
  • 4 x 1.8 TB
  • De-duplication and Compression is enabled.
  • vSAN Capacity is currently:
  • Total: 72 TB
  • Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased. Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

Options

  • AInstall an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
  • BUpdate the existing Disk Group, and claim the newly installed drives for each node.
  • CCreate a new Disk Group, and claim the newly installed cache and capacity SSD drives for each
  • DInstall an additional 3 x 1.8 TB SSDs per vSAN node.
  • EReplace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
