HI
We have few customers than have 2 Sites (Active/Active using SS
replication) + 3rd site as Quorum Tie Breaker node.
1) Spectrum Scale 4.2.3.x
2) Lenovo x3650 -M4 connect via FC to SVC (Flash900 as external storage)
3) We run all tests before deliver the system to customer Production.
Main items to take into account :
1) What is the latecny you have between the 2 main sites ?
2) What network bandwidth between the 2 sites ?
3) What is the latency to the 3rd site from each site ?
4) Which protocols plan to be used ? Do you have layer2 between the 2
sites , or layer 3 ?
5) Do you plan to use dedicated network for GPFS daemon ?

Subject: [gpfsug-discuss] Experiences with Synchronous Replication,
Stretch Clusters, and Spectrum Scale <= 4.2
Sent by: gpfsug-discuss-boun...@spectrumscale.org
Hi All,
I was wondering what experiences the user group has had with stretch
4.x clusters. Specifically, we're interested in:
1) What SS version are you running?
2) What hardware are you running it on?
3) What has been your experience with testing of site-failover
scenarios (e.g., full power loss at one site, interruption of inter-
site link).
Thanks so much for your help!
Stewart
