2 – General Description
Remote SAN Island Connectivity
Additional requirements for this configuration are as follows:
At least one FC Port of SANbox 6142 should be connected to FC SAN
■
iSCSI/ GE (GE identifies Gigabit Ethernet ports on the router) Port IP addresses
■
of remote router and iSCSI/GE port IP addresses of local routers must be
accessible by each other.
Remote SANbox 6142 management port IP address and local SANbox 6142
■
management port IP address must be accessible by each other.
When connecting SANs over long distances, it is important to determine the
round-trip latencies between two router connections. Round trip latencies can be
discovered using "Ping" command in CLI. Please
Using this round trip latency number, refer to the section on "Performance tuning"
(see section 3.5)
window scaling is set to 1, (64K) TCP window size.
To map remote FC devices to local SAN, follow these steps:
1. If the remote router is not already associated with a local router, use either
SANsurfer "Add Remote Router" wizard
command "remotepeer add"
with each other.
2. Use SANsurfer "Map Remote Initiator/Target" wizard
CLI "remotemap add" command
target mapping.
