Planning and Designing

A customer wants to host a new set of applications with high-performance requirements, specifically low latency.

The applications must be hosted at company-owned edge locations, each with limited rack space (three host slots per edge location for this project).

Which deployment option would meet the customer’s requirements while maximizing the capacity available per deployment?

  • A A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge locationEach application VM configured with a RAID-5 VM storage policy
  • B A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge locationEach application VM configured with a RAID-1 VM storage policy
  • C A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge locationEach application VM configured with a RAID-1 VM storage policy
  • D A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge locationEach application VM configured with a RAID-5 VM storage policy
Explanation

A three-host vSAN ESA cluster supports an FTT=1 ESA-optimized RAID-5 policy, whereas vSAN OSA RAID-5 requires at least four hosts. RAID-5 erasure coding uses less capacity overhead than RAID-1 mirroring, so ESA RAID-5 provides the greatest usable capacity within the three-host limit while preserving all-flash, low-latency performance.
