Storage Area Network Configurations for RA8000/ESA12000 on Windows NT-Intel Application Note

SAN Configurations for RA8000/ESA12000 on Windows NT - Intel
Page 24 AA–RHH6B–TE
SAN Configuration 6 Server/Storage Connectivity Rules
• Any mix of Windows NT Intel Servers - standalone or clustered, and storage systems using these
maximums. Assumes 1 FC HBA per server, an even storage port count, and no EBS ports.
• 16-port FC Switches, total number of switch ports available for Servers and Storage is 52
Maximum Server Connectivity,
Up to 40 Servers and 3 Storage Systems (12 storage ports/6 Active, 6 Standby)
[64 – 12 ISL ports – 12 storage ports = 40 server ports]
Maximum of 16 servers configured on any one controller pair
Maximum of 8 servers configured on any active controller host port
Or Maximum Storage Capacity,
Up to 12 Storage Systems (46 storage ports/23 Active, 23 Standby) and 6 Servers
[64 – 12 ISL ports – 6 server ports = 46 storage ports]
Maximum of 4 active controller host ports per FC HBA
• 8-port FC Switches, total number of switch ports available for Servers and Storage is 20
Maximum Server Connectivity,
Up to 16 Servers and 1 Storage System (4 storage ports/2 Active, 2 Standby)
[32 – 12 ISL ports – 4 storage ports = 16 server ports]
Maximum of 16 servers configured on any one controller pair
Maximum of 8 servers configured on any active controller host port
Or Maximum Storage Capacity,
Up to 4 Storage Systems (16 storage ports/8 Active, 8 Standby) and 4 Servers
[32 – 12 ISL ports – 4 server ports = 16 storage ports]
Maximum of 4 active controller host ports per FC HBA
• All HSG80 array controllers configured in Transparent Failover Mode
NOTE
High availability storage using Secure Path for Windows
NT and Controller Multiple-bus Failover Mode is currently
not supported in this configuration.
SAN Configuration 6 Fabric Rules
• Total Switches = 4, 16-port or 8-port
• Maximum Switch Hops (nominal ) = 1
• Maximum Switch Hops (worst case ) = 2
• Maximum number of ISLs between any two switches = 15
• Maximum Distances:
Up to 500 meters per FC cable segment, 1.5 km total server to storage (2.0 km worst case)
when using 50 micron multi-mode fibre optic cable. Refer to general Fabric rules for other
cable types
Up to 10 km per inter-switch link, 11 km total server to storage (21 km worst case) when
using 9 micron single mode fibre optic cable and long wave GBICs
SAN Configuration 6 Notes
• Each FC Switch must have a unique domain number (Domain_ID)
• When configured with greater than 4 Windows NT Servers per active controller host port,
classified as an “NT Extended Configuration” (refer to the StorageWorks Windows NT Platform
Kit FC Software Setup Utility
• For servers accessing controller host port 1 use LUN number and offset values in the range of 0 –
99, for controller host port 2 use number and offset values in the range 100 -199
• Depending on the specific number of servers and storage systems utilized in this SAN
configuration, it is possible to exceed the available total number of connection name entries in a
