Windows Connectivity: Best PracticesUse storage system-based RAID
RAID type should be based on Application I/O pattern
Use basic disks
8 kB page size for MS 2007 Exchange and 16kB for MS 2010 Exchange
Align LUN on a 1024 kB boundary with Diskpart when needed

Data Alignment• Alignment of data to LUN structure• Important when OS writes data to beginning of LUN• Misaligned data
causes disk crossings may not allow stripe alignment of large, uncached writes
• Windows 2008 and 2012 automatically aligns partitions at the 1 MB boundary no user intervention is required Refer to Microsoft KB Article 929491

Initiator Registration Records: Fibre
Number of initiators is model dependent
An initiator is an HBA or CNA port that can access the storage system• Some HBAs and CNAs have two ports• Each path consumes one initiator recordAccess from a server to an SP in a storage system can be: • Single path• Multipath• Alternate path

Initiator Registration Records Format: Fibre Channel• Hostname• Host IP address• Host HBA WWNs
128 bit number - WWNN + WWPN• VNX port WWNs
128 bit number - WWNN + WWPN• Operating system type
Allows appropriate response to host SCSI commands

Windows Connectivity Steps
Check and validate all host to VNX connectivity (FC and iSCSI)•OCManager utility (Emulex)
•SANsurfer (Qlogic)
•Unisphere Host Initiator option
•Unisphere Server Utility
Create a storage
group, add LUNs and connect
your Windows
host
Run Windows Disk Management•Rescan or reboot may be required
Initialize the disk•Write signature on disk (LUN)
Add drive letter(s)
Format the disk (LUN)
Write data to the disk

Host Registration
• Automatically• Manually
Registration makes a host known to the storage system
• Fabric logins tell the VNX which ports and HBAs are connected
• iSCSI logins tell the VNX which ports and initiators (hardware or software based) are connected
Connectivity depends on the protocol being used:

SummaryKey points covered in this module:• Connectivity requirements include:
Supported HBAs, HBA drivers, vendor management software, and proper cabling to the fabric switches.
Fabric switches properly configured and zoned Management station with supported OS, Web Browser, Java, and
network connectivity to the VNX.• Several configuration are key to successful host integration, such
as initiator records and port properties• Steps to implement Windows connectivity in both a Fibre
Channel and iSCSI environment
