SANbox 6140/6142 Intelligent Storage Router
The QLogic SmartWrite™ feature provides substantial performance
improvements in long distance replication write performance over
DS3/T3 (44.736 Mbps) line rates. This in turn boosts the performance of
third-party replica
tion solutions over the WAN link. By reducing the num-
ber of round trip delays on WRITE operations down to one, SmartWrite
becomes a “must have” feature when you implement data replication
over IP networks which exhibit un-predictable la
tencies but in turn give
you the ability to keep the sites thousands of miles apart.
CONNECTING A MULTI-VENDOR FIBRE CHANNEL SAN
In a Fibre Channel SAN, the name server maintains registration informa-
tion for all ports and devices that are connected to the SAN. When a SAN
grows to over 256 Fibre Channel ports, there can be issues with scaling
the name server.
In addition, practical issues like security don’t call for merging SANs into
a “mega SAN”. In a corporation, Human Resources might prefer to have
their SAN isolated from an Engineering department SAN. However, both
department SANs might need to share a ta
pe library at the data center for
backup. To complicate matters, the HR SAN might use switches from one
switch vendor, while the engineering department SAN might use a
Director c
lass switch from another switch vendor.
To compound this issue, multi-vendor SANs connected via E_ports invari-
ably required loosing some of the management functionality offered by
one of the SAN vendors.
By using the QLogic SANbox 6142 Series to inter-connect such multi-
vendor SAN switches, customers can work around this E_port connectiv-
ity issue. QLogic SANbox 6142 Series uses N
-
Port and NL
-
Ports for inter-
SAN routing. Up to 4 FC SANs can be inter-connected using the QLogic
SANbox 6000 Series in this manner.
The QLogic SANbox 6142 Series enables a solution where there is no
longer an issue with scaling name servers nor is there a need to loose
one vendor's high level switch software functionality for the sake of inter-
connection with another vendor's SAN switch.
This simplifies storage provisioning across multi-vendor SANs within the
data center and provides investment protection for all multi-vendor SAN
equipment purchases.
