Remote User Workstations - HP 316095-B21 - StorageWorks Edge Switch 2/24 Planning Manual

Remote User Workstations

Customer system administrators determine whether to allow access to directors
from remote workstations. If administrators allow remote sessions, they may
restrict access to selected workstations by configuring the IP addresses of those
workstations through the HAFM application. When a remote session is allowed,
the remote user has the same rights and permissions as if the session were on the
local HAFM appliance. Up to 25 HAFM application sessions can be
simultaneously active (one local from the HAFM appliance and 24 remote).
Remote workstations must have access to the LAN segment on which the HAFM
appliance is installed. Director administrative functions are accessed through the
LAN and server.
The LAN interface can be:
SAN High Availability Planning Guide
Installing additional rack-mount products — When installing an additional
director or switch, the length of Ethernet cable required to provide LAN
connectivity is a function of rack position (top, bottom, or adjacent to the
slide-out drawer). Ensure cable lengths provide sufficient cable inside the
rack to route to the product's Ethernet ports and to allow service clearance.
Interconnecting equipment racks — To increase the products managed by
one HAFM appliance, Ethernet hubs in one or more equipment racks must be
connected. Plan for an Ethernet cable length that meets the distance
requirement between the racks. In addition, plan for an additional 1.5 meters
(5 feet) of cable outside the rack to provide slack for service clearance, limited
rack movement, or inadvertent cable pulls. Store extra Ethernet cable in the
rack or under the computer room raised floor.
Consolidating HAFM appliance operation — For control and efficiency,
all directors and switches in a multi-switch fabric should be managed by one
HAFM appliance. When products in two or more racks are joined to form a
fabric, the PC environment should be consolidated to one server and one or
more clients. Plan for Ethernet cabling to interconnect racks and ensure all
directors, switches, and PC platforms participating in the fabric have unique
IP addresses.
Part of the customer's public 10/100 Mbps LAN segment that provides access
to managed directors and switches. This product-to-HAFM appliance
Ethernet connection is part of the equipment rack installation and is required.
Connection of remote workstations through the hub is optional. This type of
network configuration using one Ethernet connection through the HAFM
appliance is shown in Figure 55. Director 2/64s are used as an example.
