Benefits
The RackSwitch G8124E switch is considered particularly suited for these clients:
Clients who are looking for ultra low latency 10 GbE networking
Clients who are looking to converge their SAN and LAN and needing a FCoE transit switch
Clients who are looking for ways to reduce cost (CAPEX)
o
Converge LAN and SAN traffic
o
Purchase fewer adapters, transceivers and cables per server
o
Reduce upstream switching costs – fewer ports
Clients who are looking to reduce complexity (OPEX)
o
Fewer adapters to manage
o
Manage fewer cables helping reduce potential points of failure
o
Ability to standardize on Ethernet from all servers, Ethernet for all connectivity in a rack
o
Ability to push out FC split to the end of the row
The RackSwitch G8124E offers the following benefits:
High performance: The 10 GbE low latency (as low as 570 nanoseconds) switch provides the best
combination of extremely low latency, non-blocking line-rate switching and ease of management.
Lower power and better cooling: The G8124E uses as little power as two 60 W light bulbs, which is
a fraction of the power consumption of most competitive offerings. Unlike side-cooled switches, which
can cause heat recirculation and reliability concerns, the G8124E rear-to-front cooling design reduces
data center air conditioning costs by having airflow match the servers in the rack. In addition, variable
speed fans assist in automatically reducing power consumption.
Virtual Fabric can help customers address I/O requirements for multiple NICs while also helping
reduce cost and complexity. Virtual Fabric allows for the carving up of a physical NIC into multiple
virtual NICs (2 - 8 vNICs) and creates a virtual pipe between the adapter and the switch for improved
performance, availability, and security while reducing cost and complexity.
VM-aware networking: VMready software on the switch helps reduce 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 VM providers such as VMware, Citrix, Xen,
IBM PowerVM, and Microsoft Hyper-V.
Layer 3 functionality: The 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 protocols from static routes for technologies such as Open Shortest Path First
(OSPF) and Border Gateway Protocol (BGP) for enterprise customers.
Seamless interoperability: RackSwitch switches interoperate seamlessly with other vendors'
upstream switches. For more information, see Tolly Reports: Tolly Functionality and Certification:
