Hi all
In my scenario I have 3 datacenter in the same campus. Mean I have multi 10Gb/s LAN connectivity between the rooms.
Only a handful VM's, but i await max resilience.
Facts:
3 rooms
1 Host per room
Allflash (8x 800GB SSD per host)
Now my question, what is the better design?
A: Standard design FTT=?
B: Stretched cluster design
C: something that I don't now
many thanks in advance...
Hello STRI,
With a 3-node cluster (stretched or standard), max is FTT=1 .
Standard-cluster requires <1ms latency between nodes/rooms and would be the preferred option here. In a stretched-cluster the Witness-node requires very little utilization and only a tiny amount of storage so a full box would be overkill (you could pull must of the storage out of it or use a Witness VM instead if going stretched).
