Overview
10/40GbE Switch
High performance blade
provides maximum
throughput, flexibility, and
iSCSI / FCoE convergence.
10GbE Plug and Play
Converge infrastructure
and connect easily to 3rd
party networks with this
flexible Layer 2 blade.
10GbE Basic
Transition to 10GbE
connectivity and extend an
available iSCSI / FCoE fabric
with this Layer 2/3 switch.
Ethernet / FC Switch
Connect directly to the Fibre
Channel SAN and Ethernet
LAN without the need for an
FCoE forwarding device.
1GbE High-density
Leverage existing Ethernet
cabling to enable broader
scalability in the data center
with this Layer 2/3 switch.
1GbE Basic
Flexible Layer 2/3 switch
with dual expansion slots
allowing you to customize
connectivity options.
Direct connection
Transparently connect 16
Dell blade servers into the
Local Area Network of your
choice at 10Gb speeds.
