Hello,

we are going to have a project with 48x900gb sas hitachi hus.migration the vms from old storage to hitachi.

There are 100 vms mostly windows 7,some linux.5 esx hosts per fiber channel switch and one storage and with isl connected with other 5 hosts and other storage.

Because the disk are too big i am thnking for a mix of raid 5 7+1 and 2 raid 10 raid groups in 2 pools from hitachi,wide stripping.

but when i present too big lun in esx will be a problem of scsi reservations?or it is only when i have too many intensive vms in one datastore?i want to keep 1 lun=2 datastores.

Hitachi has 2 controllers.all luns i will present from 2 ports in each controller or is better one port per controller ?every esx should see tha same luns.is it correct as implementation?its my first project and i dont have too much experience.
