I'm trying to understand SAN storage a bit further, I work in a risk team not an IT technical team, but if you took on an infrastructure role what kind of details would you want to know about your storage? How do you profile/document a SAN? To gather some useful questions about your SAN what kind of questions would you ask?

Visit the following http://www.snia.org/education to get more info, to see that SAN (Storage Area Network) is a complete network, consisting of storage arrays, servers, switches, ..etc



I would consider the following points in my Audit reports:

RAID (RAID 0, 1, 5, 6, 10)
Enclosure RAS services and diagnostics
Performance (processor technology)
High availability
Capacity  Volume management
Performance  I/O
Reliability
Data protection features
WAN  Replication  (Data Replication)
Dynamic Snapshots (Flash Copy)
Licenses  of  OEL, PTC, Copying over WAN
Internal UPS or Batteries
Microcode Updates
Zoning

Why type of SAN is it?

Fibre Channel
iSCSI
NFS

is it a NAS or SAN?

from VMware perspective...

vSphere Storage Guide

VMware, actually creates some nice Storage Maps, e.g. Maps Virtual Machines, to LUNs, on SANs, so you can print out where the virtual machines are stored.

Are there many common suppliers of SAN's? Who are the main players in this area? And do they come in allsorts of models? I.e. what would a top level SAN have that a lower level (cheaper) SAN doesnt?

I would speak to multiple sets of vendors as HP/IBM/EMC to see their products more in depth. Make sure you check the following: Interoperability, Management, Reliability, Performance , functionality, Value.
