"ost Adapter er#ormance Considerations

A sin$le host adapter :ill not provide #%ll line rate ,and:idth :ith all ports

active + Customers should not plan to drive the Ports/Links/Host Adapters to their

defined limits

Most o# these recommendations :ill ,e needed in cases :here the

%tili;ation is ver' hi$h

+ .%nnin$ onl' 10 MB per second per port :ill never overload a host adapter

+ B%t tr'in$ to r%n 200 MB per channel :ill de#initel' have severe per#ormance

impact :hen all ports are %sed #or eample on a S!00

I# in do%,t $et .M< or TC data and %se isk Ma$ic

Start plannin$ #or additional reso%rces :hen 'o% reach approimatel'

n%m,er #or one da')

>ach S!000 host port has an internal *%e%e depth o# 20-! per port
