t Enterprise Application Support ServerIron can be deployed in many Enterprise environments where IP-based applications are used,including the popular applications like Oracle, BEA WebLogic,IBM WebSphere,PeopleSoft and Siebel. ServerIron supports custom features for load balancing and persistence for many such applications t Server Connection Offload The ServerIron increases server performance,availability,response time and security by offloading connection management from the servers.using persistent HTTP 1.0 and 1.1 connections to the server,the ServerIron multiplexes large number of client-side connections to a few server-side connections.connection offload allows the servers to focus on mission-critical high-performance application service delivery. t Comprehensive health checks to servers and applications to detect downed resources in real time and redirect users.highly flexible and customizable health checks using layer 2,3,4 and 7,and boolean and scripted health checks.layer 7 health checks can include the following:http,dns,smtp,pop3,ldap, NNTP,IMAP4,FTP,Telnet,RADIUS,and others. t Fully integrated and complete Layer 2/3 switching and routing in a Layer 4-7 switch for wire-speed performance,including support for always-on sflow network monitoring t Simplified server farm management with automatic detection of downed resources and redirecting users,support for graceful shutdown of servers for maintenance,and slow start to bring new servers up to full capacity IronShield Security t SYN-Guard ServerIron protects server farms against multiple forms of Denial of Service (DoS) attacks,such as TCP SYN and ACK attacks,by monitoring and tracking session flows.only valid connection requests are sent to the server. ServerIron 450 and 850 switches are capable of defeating DoS attacks at the industry s highest rate of up to 5 million SYN/sec to meet growing security threats. t Intelligent TCP and UDP Connection Rate Limiting ServerIron further protects server farms,firewalls and cache servers by controlling the rate of TCP and UDP connections on an application port basis.controlling the rate of new connections that each device receives ensures availability despite increased levels of activity due to DDoS attacks or surges in user access. t Transaction Rate Limiting ServerIron protects real servers against malicious attacks from high-bandwidth users by allowing administrators to configure a threshold for the rate of incoming packets for applications t High Performance Access Control Lists (ACLs) and Extended ACLs By using ACLs,network administrators can restrict access to specific applications from a given address or subnet. Filters can be easily set to deny access to servers by any particular port or VIP address.for example,a network administrator can deny FTP traffic to a particular address.conversely,filters can be set to allow access by a subset of users or subnets. 1 2 1 2 DoS Attacks TCP SYN TCP SYN ACK TCP SYN TCP SYN ACK Filtered and Blocked Application Messages INTRANET/ EXTRANET DoS Attack Defeated Legitimate Connections ServerIron 450 Switch Application Servers Clients Application Message with Virus and Worm Content t Figure 3: Securing the Server Farms and Applications from High-Speed Malicious Attacks 5

High Availability Services t Remote Backup Servers If no local servers or applications are available,serveriron sends client requests to remote servers.the remote server can be another server farm managed by ServerIron switches or just another group of real servers.by defining multiple remote servers,serveriron will load balance the traffic among them using the selected load balancing method. t HTTP Redirect ServerIron can also use HTTP redirect to send traffic to remote servers if the requested application is not available on the local server farm t Active/Standby When deployed in active-standby mode, the standby ServerIron will assume control and preserve the state of existing sessions in the event the primary load-balancing device fails.configuration common to the two ServerIron switches can be automatically synchronized to avoid manual replication. t Active/Active When deployed in active-active mode,both ServerIron switches work simultaneously and provide a backup for each other while supporting stateful fail-over.configuration common to the two ServerIron switches can be automatically synchronized to avoid manual replication. t Redundant Power Supplies ServerIron 850 supports multiple (up to three additional) hot-swappable power supply options,and the ServerIron 450 supports dual hot-swappable power supplies Disaster Recovery and Global Server Load Balancing ServerIron redirects client traffic globally by site availability, site load, and site response time. ServerIron also measures client/server proximity as defined by round trip delay and geographic location. All these features can work in conjunction with the network s existing DNS servers and results in minimizing network disruption when implementing GSLB. ServerIron continually monitors the sites to detect any changes in servers or services due to varying health and traffic conditions. Configurable site load thresholds enable network administrators to fine tune the health checking parameters to best suit the site s server and service capabilities. FlashBack,a unique Foundry Internet traffic management feature,measures response time between the authoritative DNS site and each data center.serveriron actually computes proximity based on the round trip time between the different global sites and uses these measurements as a benchmark to determine site responsiveness and the site s range to the client. In addition,serveriron uses geographic site selection to keep the requests within continental domains. ServerIron constantly monitors application traffic to create a knowledge base that enables a more intelligent GSLB methodology, powering smarter site selection criteria. ServerIron handles server farm outages or overloads even after the DNS lookup by automatically triggering HTTP redirection or implementing remote server load balancing.serveriron GSLB provides the following: t Acts as a DNS proxy to transparently intercept and modify the DNS responses,thereby directing customers to the best site t Handles server farm outage or overload after the DNS lookup by HTTP redirect or remote server load balancing t Leverages the existing DNS server and minimizes disruption to the existing DNS environment t Provides continuous site monitoring to detect changes in site health conditions t Allows the network administrator to tune individual site load thresholds through configurable settings t Monitors and selects sites based on FlashBack speed,which measures performance using site,server and application responsiveness t Adds an evolutionary knowledge based in the global server load balancer that enables smarter site selection as more clients access the site t Grants the network administrator the ability to tune ServerIron settings and ensure that minimal differences in various site metrics do not affect site selection Foundry offers another unique Internet application management feature called Global IP. Powered by unique VIP health checking algorithms, Global IP injects routes to client application services based on regional data center server-farm health and provides GSLB capability without relying on the DNS protocol.this enables ISPs and enterprises to instantaneously build networking infrastructures on a global basis and offer ready-to-go differentiated services to customers for multi-site deployments. Transparent Cache Switching ServerIron switches improve Internet response time and decrease WAN access costs by redirecting web traffic destined for remote Internet hosts to local cache servers. Foundry s Transparent Cache Switching (TCS) can be used with any cache server that supports transparent redirection, including those from leading vendors such as CacheFlow, Cobalt, Compaq, Dell, Inktomi (a Yahoo company), Network Appliance,and Novell. Foundry s TCS offers network managers a resilient web caching solution that significantly simplifies administration. Unlike proxy server solutions that require manual 6

configuration of each client s browser, ServerIron transparently intercepts and switches HTTP client requests to an available cache server without reconfiguring the client s browser. Network administrators can configure the device to switch traffic based on source and destination IP address. ServerIron switches provide the industry s most powerful content-aware cache switching features to build intelligent content networks that route traffic based on content rather than just IP addresses. The ServerIron TCS application includes the following content-switching features: t Intelligent load balancing of caches to eliminate content duplication,increase cache-hit ratio,and improve the Internet response time t Accelerate delivery of dynamic content and optimize the cache utilization by bypassing the caches automatically for dynamic content t Specify content-based rules to determine what content should be cached t Organize caches into logical groups that serve different content to provide differentiated service offerings to content providers Technical and Physical Specifications Load Balancing Methods - Least connections - Response time - Response time + least connections - Round robin - Weighted distribution - Bandwidth and Weighted Bandwidth - Host Proximity Layer 2 Switching Capabilities - 32,000 MAC addresses - 802.1d Spanning Tree Protocol - 802.1p prioritization - Policy-based VLANs - Port-based VLANs - Layer 3 protocol VLANs - Layer 3 protocol and subnet VLANs - 802.1q VLAN tagging Protocol Support - TCP - POP3 - UDP - DNS - SSL - BootP - FTP - TFTP - Telnet - SNMP - SMTP - VRRP/VRRPe - HTTP - IPSec - IMAP4 - RADIUS - LDAP - VoIP - NNTP Standards Compliance - 802.3, 10BaseT - 802.3u 100BaseTX, 100BaseFX - 802.3z 1000BaseSX - 802.3z 1000BaseLX - 802.3x Flow Control - 802.1q VLAN Tagging - 802.1d Bridging - 802.1w RSTP - 802.1ad Link Aggregation - 802.3 Ethernet Like MIB - Repeater MIB - Ethernet Interface MIB - SNMP V1 - SNMP MIB II Network Management - Integrated Command Line Interface - SSH - Web-based GUI - Telnet - SNMP - RMON - IronView Network Manager (INM) - HP OpenView Warranty - 1 year hardware - 90 days software - Upgrades to higher levels available Mounting Options - 19" Universal EIA (telco) Rack - Tabletop Platform ServerIron 450 ServerIron 850 Concurrent sessions 15,000,000 15,000,000 Throughput 56 Gbps 56 Gbps Switching capacity 128 Gbps 256 Gbps Packet forwarding rate 48,000,000 pps 84,000,000 pps Number of 10/100 ports 48 144 Number of Gigabit ports 48 112 Total number of ports 64 160 Layer 3 switching capabilities OSPF,RIPv2, VRRP, VRRP-E, OSPF,RIPv2, VRRP, VRRP-E Supports servers on different subnets Supports servers on different subnets from that of Virtual IP address from that of Virtual IP address Physical dimensions 8.75" h x 17.5" w x 15" d 20.75" h x 17.5" w x 15.25" d (22.2 cm x 44.5 cm x 38.1 cm) (52.7 cm x 44.5 cm x 38.7 cm) Weight 60 lbs fully loaded (29.9 kg) 117 lbs fully loaded (43.7 kg) Power requirements 4-slot Chassis with Single (1) Power Supply: 8-slot Chassis with Single (1) Power Supply:Input Input Voltage and Current Power Supply Voltage and Current Power Supply Rating -70 to Rating -70 to -40 VDC:17A 100 to 120 VAC -40 VDC:17A 100 to 120 VAC (auto-ranging): (auto-ranging):8a 200 to 240 VAC (auto- 8A 200 to 240 VAC (auto-ranging):4a AC line ranging):4a AC line frequency:47 63 Hz frequency:47 63 Hz 7
