Cisco SFS 7000D Series InfiniBand Server Switches

Q. What are the Cisco

SFS 7000D Series InfiniBand switches?

A. A. The Cisco SFS 7000D Series InfiniBand switches are a new series of high-performance InfiniBand switches that deliver

next-generation InfiniBand performance and flexibility with autosensing dual-speed DDR/SDR InfiniBand 4X ports that support

20-or 10-Gbps per port. These switches, in common with the SFS-7000P series switches, are designed with best-in-class reliability,

high availability, and serviceability features. The Cisco SFS 7000D Series provides the foundation for interconnecting servers with

industry-standard DDR (20-Gbps) or SDR (10-Gbps) full duplex, low-latency InfiniBand. The Cisco SFS 7000D Series switches

are ideal foundation for high-performance server clusters or for enterprise grids when used inconjunction with Cisco VFrame Server

Fabric Virtualization Software.

Q. What business benefits does high-performance, low-latency InfiniBand switching provide?

A. The Cisco SFS 7000D Series switches provides a new class of data center infrastructure that interconnects discreet server resources

together into a high-performance, 20- or 10-Gbps, low-latency fabric. The increased bandwidth and support for Remote Direct

Memory Access (RDMA) and low latency (<4 usec user-space latency) switch is ideal for applications that demand high-bandwidth

and low-latency. These technologies enable industry-standard servers to be combined into effective high-performance clusters and

grids. In addition to high-performance computing, InfiniBand also offers the performance, security, and control required for utility

computing. The Cisco SFS 7000D Series interconnects servers through a high-performance, unified compute fabric, and when

combined with Cisco SFS 3000 Series multifabric server switches, allows shared pools of I/O and storage resources that can be

mapped together by Cisco VFrame Server Fabric Virtualization Software to deliver virtual “compute services.” Another tangible

benefit delivered by the SFS-7000D series InfiniBand switches is providing a future proof compute switching fabric investment.

By investing in DDR capable infrastructure today, as server technologies evolve and provide greater PCI-Express performance,

Q&A Cisco SFS 7000D Series InfiniBand Server Switches Q. What are the Cisco® SFS 7000D Series InfiniBand switches? A. A. The Cisco SFS 7000D Series InfiniBand switches are a new series of high-performance InfiniBand switches that deliver next-generation InfiniBand performance and flexibility with autosensing dual-speed DDR/SDR InfiniBand 4X ports that support 20-or 10-Gbps per port.

the potential of InfiniBand DDR can be realized without upgrading the entire InfiniBand fabric, thereby delivering significant savings over the life-time of the infrastructure. Q. Do the Cisco SFS 7000D Series switches support and work with Cisco VFrame Server Fabric Virtualization Software? A. Yes. The Cisco SFS 7000D Series switches fully support enterprise and research server grid deployments based on Cisco VFrame Server Fabric Virtualization Software.

in the InfiniBand fabric and still have full access to Ethernet or Fibre Channel I/O connectivity provided by the Cisco SFS 3000 Series. Q. How do I use the Cisco SFS 7000D Series to build InfiniBand fabrics larger than the size of a single switch? A. InfiniBand fabrics, for both high-performance computing and unified I/O grids, which are larger than a single switch, are built with 2-tier designs by connecting multiple switches together.

Q. What effect does the blocking factor have on SFS InfiniBand fabric performance? A. The blocking factor has absolutely no effect on fabric latency or ability to access I/O resources. However, blocking factor does affect worst-case throughput from server to server. Servers on a 50 percent blocking factor fabric will have half of the maximum bandwidth, 20 Gbps, or 10 Gbps available in the worst case. Servers on a 67 percent blocking factor fabric will on average have one third of the maximum bandwidth or 6.

Q. What type of monitoring is supported on the Cisco SFS 7000D Series switches? A. The Cisco SFS 7000D Series has many different monitoring options. It is possible to get gather performance information on a portby-port basis in real time. This information includes raw performance data as well as error rates and packet statistics. This data can be expressed as updated text in tables or as live moving graphs over time. It is also possible to graph and compare a number of different data sets at the same time.
