BNT 1Gb/10Gb G8000 RackSwitch for IBM System x
IBM System x at-a-glance guide
BLADE Network Technologies’ (BNT) 1Gb/10Gb G8000 RackSwitch for IBM® System x® (Figure 1) is a
Top of the Rack (TOR) switch that delivers unmatched line-rate Layer 2/3 performance at a very attractive
price. It has 44x 1GbE RJ45 ports, four 1G SFP ports, and standard redundant power supplies along with
up to four optional 10GbE SFP+ or CX4 ports. Unlike most rack equipment that cools from side to side,
the RackSwitch G8000 has rear-to-front airflow that matches server airflow.

BNT 1Gb/10Gb G8000 RackSwitch for IBM System x 3
Summary: BNT 1Gb/10Gb G8000 RackSwitch for IBM System x
The BNT 1Gb/10Gb G8000 RackSwitch offers the following benefits:
z
High performance: The G8000 provides up to 176 Gbps throughput and supports up to four 10G
uplink ports for a very low oversubscription ratio.
z
Lower power and better cooling: The BNT G8000RackSwitch uses less power than two 60 W light
bulbs -- a fraction of the power consumption of most competitive offerings. Unlike side-cooled
switches, which can cause heat recirculation and reliability concerns, the G8000 RackSwitch
rear-to-front cooling design reduces data center air conditioning costs by matching airflow to the
server’s configuration in the rack. Variable speed fans assist in automatically reducing power
consumption.
z
VM-aware network virtualization: BLADE VMready software on the switch reduces configuration
complexity while significantly improving security levels in virtualized environments. VMready
automatically detects virtual machine movement from one physical server to another, and instantly
reconfigures each VM’s network policies across VLANs to keep the network up and running without
interrupting traffic or impacting performance. VMready works with all leading hypervisors, such as
VMware, Citrix Xen, and Microsoft.
z
Layer 3 functionality: The BNT switch includes Layer 3 functionality, which provides security and
performance benefits, as inter-VLAN traffic stays within the chassis. This switch also provides the full
range of Layer 3 static and dynamic routing protocols including Open Shortest Path First (OSPF) and
Border Gateway Protocol (BGP) for enterprise customers.
z
Active MultiPath (AMP™): This effectively doubles bandwidth by allowing all uplink ports to be
active/active, eliminating cross-stack traffic and providing up to 900Gbps aggregate bandwidth
between servers. Built-in fault tolerance constant health checking ensures maximum availability.
z
Fault tolerance: These BNT switches learn alternate routes automatically and perform faster
convergence in the unlikely case of a link, switch, or power failure. The switch uses proven
technologies such as L2 trunk failover, advanced VLAN-based failover, VRRP, HotLink™, Uplink
Failure Detection (UFD)™, IGMP V3 snooping, and OSPF.
z
Seamless interoperability: BNT switches interoperate seamlessly with other vendors' upstream
switches. See the Tolly Functionality and Certification: RackSwitch G8000, G8100, and G8124 and
Cisco Catalyst Interoperability Evaluation at
http://www.bladenetwork.net/userfiles/file/PDFs/Tolly209116BladeRackSwitchInteroperability.pdf.
z
Stacking: Cluster virtualization, single IP, and stacking of up to six virtual switches allow configuration
of multiple switches as one, saving valuable time, IP addresses, and resources.
The BNT switch comes with an IBM limited three-year hardware warranty.
