Exam 2V0-21.20 topic 1 question 97 discussion

A & D is correct

1 SSD and 2 HDD are for better performance, but the minimum is 1 SSD and 1 HDD. A and D are correct for hybrid config. https://www.vmware.com/resources/compatibility/vsan_profile.html "The number of capacity tier drives in a disk group has an impact of the performance of vSAN. While a single capacity tier drive is the minimum requirement for a disk group, for better performance when there are more VMs, and better handling of rebuild/resync activities, we recommend configuring more than 1 capacity tier drive per caching tier SSD per our guidance above."

A & D is correct Disk Groups One of the more important aspects of the vSAN wizard is the creation of disk groups. Each host must have at least one disk group. By placing physical disks into them, we make each disk group available for vSAN to consume. Disk Groups will be either Hybrid or All-flash; they cannot be both. Each group must contain: Exactly one SSD for cache At least one additional disk (SSD or HHD) for persistent storage, with a maximum of seven additional disks total We can create up to five disk groups per host. The physical disks can be either internal storage or external disks directly connected to the host.

AD is Correct

A & D is correct

A & D are correct For hybrid group configuration, make sure that at least one SAS or NL-SAS magnetic disk is available. For all-flash disk group configuration, make sure at least one SAS, or SATA solid-state disk (SSD), or PCIe flash device. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-4B738A10-4506-4D70-8339-28D8C8331A15.html

Excerpt: "we recommend configuring more than 1 capacity tier drive per caching tier SSD" https://www.vmware.com/resources/compatibility/vsan_profile.html

a good explanation is: • Minimum of 3 ESXi 6.0 host that contribute storage. • At least one SSD and one Hard Disk per host. • Hosts need I/O controller supporting Pass Through or RAID 0 (prefer them to be on the VSAN Hardware Compatibility List) • VMkernel port configured for VSAN traffic. https://www.virtuallyboring.com/vmware-virtual-san-6-requirements-part-1/

A&D - One Serial Attached SCSI (SAS), SATA solid-state drive (SSD), or PCIe flash device and one to seven magnetic drives for each hybrid disk group.

A & D are correct. Passed with 500 today

A and D

Cache: One SAS or SATA solid-state disk (SSD) or PCIe flash device. Virtual machine data storage: For hybrid group configuration, make sure that at least one SAS, NL-SAS, or SATA magnetic disk is available https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-4B738A10-4506-4D70-8339-28D8C8331A15.html

A & D for sure of course the more the merrier

A&D, at least one of a kind is required

A&D for sure
