Hi
I am doing my first piece of 'architecture' type work for a SAN deployment, using HDS technology, but I am lacking some of the basic knowledge to speak well on this....
My understanding is as follows:
Install disk shelves into the SAN chassis
Configure Disks at Hardware level into RAID groups (e.g. 4+1 RAID5 sets)
....
This is where my understanding is flawed, I have heard that you need to configure 'LUNs' - and some colleagues have said these should range from 9-18GB typically for Wintel/UNIX systems.... However
What dictates this?
And if a system needs a 'volume' of 100GB - how would the LUNs be pieced together so the server can see 100GB
Hope that makes sense, and someone can offer some views!
Thanks
