Lun mapping issue

141 Views
Last Modified: 2016-05-18
informed by san team, there is lun latency increased because..

Single Lun is mapped to multiple host and cluster ?

Need to understand will that actually impact the performance ?

 if yes what is count for max host /cluster can be used to map single lun ?

any impact due to size of lun mapped to multiple hots?

best practice to look for lun latency if  caused due to vmware or san config ?

Thanks,

yes, 256 is max lun we can map!!

so no challenge[with respect to lun latency] if we map single lun to multiple hosts from same/other cluster/vcenter like it may be 10000 or more.
