7.
Zone controller port pairs -
When implementing load sharing,
create a separate zone for each pair of communicating ports (one
initiator and one target per zone). Assign the zones to different
intelligent (iFCP) ports on the SAN router. If the IP network
correctly distributes the load across two paths, then load sharing
is implemented. If the SDR or ADR application performs load
balancing across two controllers, then load balancing is
implemented. Perform zoning by node WWN. Port zoning is not
supported between mSANs (through iFCP).
8.
Do not use default zoning -
Do not implement default zoning
through the SANvergence Manager application. When
performing an installation, the application displays a single zone
named
zone1
(with corresponding
ID:1
). This zone is for default
zoning and should not be used.
9.
Dedicate storage ports to data replication -
Storage array ports
should be dedicated to SDR or ADR traffic. Do not share data
replication and local traffic applications on the same port.
10.
Set GbE switches to auto-negotiate -
SAN router GbE ports
operate only at GbE speed, therefore GbE Ethernet switches
should be set to auto-negotiate with SAN routers to provide
connectivity. The setting can be disabled only if both devices are
set to
not
auto-negotiate.
11.
Set data compression level to Auto -
Two problems associated
with data compression are incorrect algorithm selection or
compression which is ineffectual because the extended-link
bandwidth exceeds the SAN router bandwidth. Set the
compression level to
Auto
at the
Advanced TCP Configuration
dialog box (for any selected compression algorithm). Using this
compression level mode, the SAN router automatically detects if
compression can be used.
12.
Configure the iFCP timeout setting to 10 seconds -
At the
iFCP
Setup
dialog box, set the default remote timeout setting (iFCP
timeout) to 10 seconds for all ADR applications.
13.
Configure out-of-band product management -
SAN routers can
be managed through inband or out-of-band connectivity. Inband
management is provided through the same GbE connections used
for iFCP storage traffic. Out-of-band management is provided
through a data center LAN that connects servers, workstations,
and other network-related equipment. Out-of-band product
management is recommended.
