Very well, you can get them from ~maximk/tmp/spec.tar.

There are a few files that need to be edited to customize to the
particular environment:

2280-cnf:

SSC=3D set this to SSC IP address
NFX=3D - set this to management virtual server IP address

cmd-create-2280:

This contains the commands to create the virtual server and filesystems
for the spec run. It is recommended to recreate the volumes for each
spec run. We are doing the spec runs with 1 virtual server and 8
volumes, with 4 ports in aggregation mode and one ip address for the
virtual server. IP addresses and lun names in this script will need to
be modified.

cmd-clean-2280:

This file contains the commands to clean the virtual server and volumes
after the spec completion.

Clients:

This file contains the ip addresses of the spec clients. We are using 4
Linux clients, each one is 2 2GHZ CPU 2 GB memory.=20

Sfs-rc-2280:

This file contains the definitions for the spec run. The clients list
and the mount points list will need to be modified.

The spec is run with the command:

./do-spec-2280.

The scripts will create the volumes, execute the spec and collect the
performance data about the runs.=20
