  • Page 10: 6600 Series System Overview

    6600 series system overview The HP ProCurve 6600 Switch Series was designed to be co-located with data center servers for both top-of- rack edge access and end-of-row aggregation and distribution deployment models . To support high availability in a 1U form factor, all 6600 series products allow for redundant hot-swappable power supply options, hot- swappable fan tray, and front-to-back (reversible) airflow, along with out-of-band Ethernet management ports .

  • Page 11: Hp Procurve 6600 Switch Fan Tray (j9271a)

    supports only the 1200 W AC supply, although the 6600 series is capable of supporting DC and other common-slot supplies . Two AC-to-12-V DC power supplies can be configured as 1+1 redundant supplies . The system is fully powered with either power supply, and either power supply (but not both) can be removed and replaced while the system is still racked, and the switch will continue to operate .

    Figure 4: Default airflow direction and connectivity side view of the 6600-24XG switch In the event of an individual fan failure, an SNMP trap and event log entry is generated . A system can typically operate for quite a long time with a single fan failure (out of the eight), as the remaining fans can increase speed to compensate for the loss of airflow .

    switches would more likely have their network ports facing toward the back (hot aisle) of the cabinet to facilitate server connectivity . With this intention, the default configuration for the command is, “Power-to-Port”, so the “fan-pref-airflow-dir” command will not show up in the configuration file—it is the default . If the user intends to change the airflow so that the preferred direction is Ethernet ports facing the cold aisle, then in the configuration file the use should change the preferred direction to be port to power .

  • Page 15: Console Port

    Console port The console port allows for RS-232 serial connectivity for local management and configuration . For the 6600- 48G, 6600-48G-4XG, and 6600-24XG switches, the console port is an RJ-45 connector . To connect to the console, an RJ-45–to–DB-9 cable is provided with each switch to connect to the serial port on a laptop . The 6600-24G/6600-24G-4XG products offer a DB-9 serial console port for management access, and a DB-9–to–...

    Description The HP ProCurve 6600-24G Switch is a data center optimized, advanced Layer 3 1U stackable switch with 20 10/100/1000Base-T ports and 4 dual-personality ports . The 6600 series 1U form factor switches are enhanced for server edge connectivity with front-to-back cooling, redundant hot-swappable power, and redundant hot-swappable fans .

    The ASIC layout shown in Figure 8 for the data center focused 6600-24G-4XG switch adds an NGX ASIC to provide a 10-Gb uplink capability to this switch model . Unlike the 3500yl-24G switch, where the yl 10-Gb module is rear mounted, the 6600-24G-4XG switch moves the 10-Gb ports to the front of the switch for simplified cabling .

    The ProVision ASIC architecture is the latest-generation HP networking ASIC technology and is used in the ProCurve 6600 Switch Series, along with the 8200zl, 5400zl, 6200yl, and 3500yl product families . The ProVision ASIC architecture consists of multiple network chips interconnected by an active crossbar fabric chip .

  • Page 23: Policy Enforcement Engine

    Policy Enforcement Engine The ProVision network ASICs contain the Policy Enforcement Engine . This engine provides fast packet classification to be applied to ACLs, QoS, rate limiting, and some other features through an onboard Ternary Content Addressable Memory (TCAM) . Some of the variables that can be used include source and destination IP addresses (which can follow specific users), TCP/UDP port numbers and ranges (apply ACLs to an application that uses fixed-port numbers or ranges) .

  • Page 26: 6600 Series Air Plenums

    6600 series air plenums The HP ProCurve 6600 Series Air plenum is designed to help preserve cold-aisle/hot-aisle separation for improved cooling efficiency when the 6600 switch is co-located with top-of-rack servers . In typical top-of-rack server connectivity environments, the Ethernet ports face the hot aisle to align with server I/O . When a switch is mounted in a server rack, it is typically positioned toward the back of the rack to facilitate cabling, which usually leaves a sizeable air gap in the rack where cold air can flow around the switch .

    servers at the top of rack . The air plenum prevents cold air from leaking around sides of the 6600 switch to promote more efficient cooling and is recommended with installations where the 6600 switch is mounted with Ethernet ports facing the hot aisle . Figure 17 details this particular air plenum .

  • Page 34: Routing And Forwarding Tables

    Routing and forwarding tables The ProCurve 6600 Switch Series has several routing and forwarding table features that enhance routing and switching performance . Every NG/NGX interface has its own “best-match prefix” routing table that contains IP routes and is used for determining how to route the vast majority of incoming packets . Using the best-match prefix routing table is extremely fast and enables wire-speed routing to be achieved .

  • Page 35: Port

    However, when more than two ports per 4-port 10-GbE block are in a linked state, ports 1 and 4 are statically mapped to share one 14 .4-Gbps channel, while ports 2 and 3 are statically mapped to share the other 14 .4-Gbps channel .

  • Page 36: Throughput And Latency Performance Data

    Tables 7 through 9 describe the performance capabilities of the 10-Gbps, 1-Gbps, and 100-Mbps interface module ports of the ProCurve 6600 Switch Series . Over a range of packet sizes from 64 bytes to 1518 bytes, the performance levels achieved are described in terms of the following metrics: • Throughput-level percentage achieved when performing Layer 2 switching and Layer 3 routing;...

  • Page 37: Throughput Test

    . The latency figures for the ProCurve 6600 Switch Series are consistently low . Latencies this low will not be a factor in general network operation, even with streaming video or VoIP applications . The LIFO latency values are fairly consistent across all packet sizes because ingress and egress packet processors operate on the header of the frame (not the whole frame), while the full frame is buffered in and out of packet buffer memory .

  • Page 38: Power Save Mode

    . The ProCurve 6600 Switch Series has a lifetime warranty for as long as you own the product . If any part of the switch fails due to a defect in material or workmanship, including the power supply or fans, it will be replaced .

Appendix B: Policy Enforcement Engine The ProVision ASIC architecture used in the ProCurve 6600 Switch Series and the Switch 8200zl, 5400zl, 3500yl, and 6200yl Series brings a number of advanced capabilities to the network that offer a highly reliable, robust environment that leads to increased network uptime, keeping overall network costs down .

  • Page 41: Appendix C: Pim-sparse Mode

    The TCAM can support approximately 3,000 data entries that may be used to represent various traffic controls, including ACLs . For most customers, this quantity of entries will be more than adequate to provide wire-speed performance for ACL processing . Keep in mind that each ACL entry may consist of multiple criteria, such as a specific IP address and TCP or UDP port number .

  • Page 42: Appendix D: Virus Throttle Security

    Figure D-1: Virus throttle example topology On the ProCurve 6600 Switch Series, virus throttle is implemented through connection-rate filtering . When connection-rate filtering is enabled on a port, the inbound routed traffic is monitored for a high rate of connection requests from any given host on the port .

  • Page 43: Response Options

    Response options The response behavior of connection-rate filtering can be adjusted by using filtering options . When a worm-like behavior is detected, the connection-rate filter can respond to the threats on the port in the following ways: • Notify only of potential attack: While the apparent attack continues, the switch generates an Event Log notice identifying the offending host source address (SA) and (if a trap receiver is configured on the switch) a similar SNMP trap notice .
