In today's data center, applications are driving increased demand for server processing and I/O. All of this is happening at a time when budgets are shrinking. To grow to meet demand, the data center manager is forced to duplicate, isolate, and waste resources, increasing overall complexity and cost. This is because servers come in fixed packages and prevent resources from being shared. In response, architects have begun making changes to simplify the datacenter as well as consolidate and share resources across multiple customers and applications.
One key area of datacenter complexity that can be simplified is server I/O architecture. Typically, a conventional server today is deployed with multiple network adapters that server three basic I/O requirements: LAN/WAN, SAN, and inter-process communications. Servers can be deployed with multiple Ethernet network interface cards (NICs), Fibre Channel host bus adapters (HBAs), and sometime dedicated clustering interconnects. For mission-critical applications such as databases, servers can require many expansion slots. In a large data center, managing these servers as well as the morass of cables can be difficult and costly, preventing the ability to change quickly to meet business demands. There has to be a better way.
Introducing the Cisco Server Switch, a new class of data center infrastructure that provides a platform to interconnect discreet server resources together into a high performance fabric, to connect that server fabric with shared pools of I/O and storage resources, and to map the resources together to deliver virtual "compute services" based on application or business policy and priority. The Cisco Server Switch enables the delivery of utility computing by consolidating server I/O into a shared pool, significantly simplifying the server I/O architecture and enabling the virtualization of compute resources.
The Cisco SFS 3000 Multifabric Server Switch family creates a unified fabric that dramatically simplifies the datacenter architecture by running multiple types of traffic over a single physical connection. With only one interface card in each server, all resources can be managed on one fabric, eliminating the need to install and manage multiple Ethernet, Fibre Channel, and IPC cards. All types of I/O can be aggregated and load-balanced on a single 10 Gbps InfiniBand cable, reducing the number of managed host ports and increasing availability. The Server Switch then connects servers to a pool of shared Fibre Channel and Ethernet ports via line-rate gateways, and creates virtual I/O subsystems on each host, including virtual HBAs and virtual IP interfaces. When used in conjunction with VFrame server virtualization software, the Server Switch can dynamically commission or decommission this virtual I/O pool to any physical server on-demand.
The SFS 3000 Server Switch Family includes the 3012, an enterprise-class modular chassis with twelve expansion modules, and the 3001, a fixed chassis with one expansion slot. The SFS 3012 Multifabric Server Switch includes up to 24 10 Gbps InfiniBand ports on two switch modules and up to 12 expansion modules, enabling up to 96 ports in a single enclosure. The SFS 3001 Multifabric Server Switch is a fixed switch with 12 ports of 10 Gbps InfiniBand and one expansion slot. The InfiniBand-to-Ethernet Gateway and InfiniBand-to-Fibre Channel Gateway are hot-pluggable expansion modules that allow hosts attached to a unified InfiniBand fabric to share a pool of aggregated Ethernet and Fibre Channel ports.

Figure 2. Cisco SFS Fibre Channel and Ethernet Gateways
Expressly designed to apply networking principles to computing problems, the Cisco SFS 3012 uses a switched, 10-Gbps InfiniBand fabric to interconnect server resources at high performance levels. Servers can communicate with each other across the fabric using Remote Direct Memory Access (RDMA), seamlessly increasing bandwidth and decreasing latency, allowing applications to scale higher and faster by simply replacing the fabric.
Servers can also leverage the higher levels of bandwidth to communicate to existing SANs and LANs. By sharing aggregated gateway ports in conjunction with the 10Gbps InfiniBand connection, individual servers gain access to more bandwidth than an individual port would normally offer. The Server Switch also dynamically load balances across multiple gateways and multiple chassis.
With the ability to add additional hot-plug expansion modules, IT managers can manage and scale bandwidth centrally without bringing down servers. And with the ability to easily cascade multiple switches, IT managers can scale to meet datacenter requirements and protect their initial investments with the flexibility to upgrade over time.
TRANSPARENT TOPOLOGY ARCHITECTURE
The Cisco Transparent Topology Architecture allows existing IP and storage area network (SAN) tools to work out-of-the-box. Using Fibre Channel and Ethernet gateways, administrators can add virtual storage and IP interfaces to every host attached to the unified fabric. Critical storage management and network security models work out-of-the-box, such as multipathing, fabric zoning and storage-based access controls. This allows multiple hosts to share Fibre Channel connections, and still enable storage management tools to "see" each unique host. Also, by adding Ethernet gateways, IT managers can seamlessly bridge to an existing IP subnet, including VLANs, link aggregation, multicast, and other IP-based technologies.
Designed for enterprise-class redundancy, the Cisco SFS 3012 is architected for enterprise-class high availability and redundancy. By combining dynamic load balancing and port aggregation, The Cisco SFS 3012 minimizes failure points in switch blades, controllers, gateways, and ports. All removable components are also hot-swappable, including controllers, power, and cooling.
The Cisco SFS 3001 also meets high-availability requirements with redundant, hot-pluggable power and cooling. The optional expansion module is also hot-pluggable. Multiple Cisco SFS 3001s can also be deployed in redundant pairs to prevent single points of failure at the system level.

COMPLETE END-TO-END SOLUTION
The Cisco SFS 3000 Series of switches joins the Cisco SFS 7000 Series InfiniBand server switches, Cisco Catalyst
® 6000 Series switches, and Cisco MDS 9000 Series Multilayer SAN Switches to create the most complete datacenter switching solution in the industry. The Cisco SFS 3001 shares common software and expansion modules with the Cisco SFS 3012 Multifabric Server Switch, offering a clear growth path while protecting existing investments.
Configuration and maintenance are simplified with an element manager graphical user interface (GUI) and full command-line interface (CLI) using serial console, Telnet, or Secure Shell (SSH) Protocol, enabling remote monitoring, upgrades, and troubleshooting. With topology transparency, existing SAN and IP management tools work upon deployment. The Cisco SFS 3012 is also fully compatible with applications that support Simple Network Management Protocol (SNMP), allowing IT managers to reduce management time and total cost of ownership.
