This is actually a bit of a tricky question IMO.
The actual recommendation in the documentation is to use multiple disk groups - I can't find a specific reference to using smaller SAS disks in any tier.
However, as a disk group must comprise of a single SSD and then multiple capacity disks (either SSD or spinning depending on hybrid or all-flash configs), the implication is that you should increase the amount of SAS disks in the capacity tier. This would allow for more parallel read/write operations - thus improving performance.
You would also have to increase the number of SSDs to increase the number of disk groups as well, but that isn't provided as an option.
Enabling View Storage Accelerator is explicitly given as a recommendation.
Therefore the correct answers are B and C.
C & E are correct RTFM !
Virtual SAN Best Practices
Get better performance from your Virtual SAN with these best practices.
• Use more, smaller SAS disks for capacity tier to get more IOPS.
• Separate the SSD device access path from the capacity tier path. Use a dedicated SAS HBA for disk-based
flash or use a PCI-E or memory slot SSD.
• Minimize the number of components as much as possible per VM.
• Enable View Storage Acceleration.
SAS is a protocol which is used to pass data from and to disks. SSD could also be connected via SAS protocol to server HBA. Since storage performance (ie number of IOPS) of VSAN (no matter Hybrid or All Flash) depends significanlty on the number of disk groups (the more disks are used for caching tier/the more groups you will create on a host), you should increase the amount of disks (SAS SSD/SATA SSD/NVMe SSD/no matter what SSD) for the caching tier. So, C+E is correct
they said sas cashe disk and sas capacity disk, so he mean sas technologie, and when we said sas disks we mean disk that use sas technologie
