• A review of present and near future technologies
  from GENROCO

2
Which pipes?

• Gigabit technologies
• Gigabit Ethernet
• HIPPI
• Gigabyte technologies
• GSN
• 10 Gigabit Ethernet
• Infiniband

3
Can you get the bandwidth?

• TCP/IP is the current protocol of choice
• TCP/IP has limitations
• Small packet size
• Checksum calculations
• High CPU utilization
• PCI bus speed limitations

4
Its not the size that counts,Its how you use
it.

• Pipe size doesnt matter if the CPU cant keep up
  with the data

5
What are other options?

• Scheduled Transfer
• Originally designed for GSN
• RDMA
• Promoted for InfiniBand
• Hardware accelerated TCP/IP
• Promoted for 10 GigE and iSCSI

6
Scheduled Transfer

• Transaction based protocol for high bandwidth,
  low latency system area networking
• An extension of DMA to the network
• Rich set of media supported
• GSN, Gigabit Ethernet, FC, OC48...
• Well defined API and application mappings
• OS Bypass
• ANSI NCITS Standard

7
10 GigE Timeframes

• Prototype Silicon - end 2001
• Prototype networks end 2002
• Production products end 2003

8
InfiniBand Timeframes

• Prototype silicon trickling out now
• Prototype networks 2002
• Production products - 2003

9
GSN is here now

• Products available today from GENROCO, SGI and
  Essential
• TCP/IP and ST implementations
• PCI and SGI XIO NICs
• Switches
• Bridges to HIPPI, GigE, Fibre Channel, OC48
• Supported on UNIX on Compaq, IBM, Sun, SGI
• Soon on HP and Linux

10
GSN Advantages

• Maximum TCP/IP frame sizes
• ANSI standard
• Reliable network
• Available now

11

  Switch Control

13
NEW! GSN Repeater/Converter

• Two GSN port device
• Each port can be optical or copper
• Copper-to-copper
• extends copper GSN links past 40m
• Copper-to-optical
• Media conversion

• Full re-clocking of data
• Self contained 1U rackmount package

14
Summary

• If you need bandwidth today, GSN is the only high
  bandwidth solution.
