Yes PERC H755 support multiple virtual disks.
Hi guys,   I have a question would like to seek your all suggestion, and here is my question:   Is R450 server allow to create more than 1 RAID group in it, and those new created RAID can be viewed by window server OS? For example, I have a DELL R450 and configured with RAID 5 for 1st 3 hard disk drive. Meanwhile, I installed a window server OS on the RAID 5 Virtual Disk. After few month, i would like to expand the capacity of the Window servers. Hence, I plan to slot in 4 additional hard disks into the server and configure 2 raid 1 Virtual Disks (2 hard disk for each RAID 1 group). Is that can be done? Inside the Window Server, will those virtual disk can be viewed and used?   Thank you.  
Is DELL R450 can create multiple RAID group, and visible by window server
