Load Balancing NewsBriefs: December 17, 1999
Keeping Holiday Traffic Flowing:
Nintendo and REI Rely on F5 Networks F5's BIG/ip measures server workload: number of connections, fastest response time, number of successful requests, and packet throughput. It then distributes traffic across servers to optimize utilization, improve response time, and redirect traffic around points of failure. Dan Lambert, Network Architecture Manager at Nintendo, explains: "It's
absolutely critical to the company's bottom line that Nintendo.com renders
great response time and is available to customers 100 percent of the time,
particularly with the upcoming holiday season approaching." Kim Muromoto,
IS Technical Services Manager at REI, agrees. "F5 Networks' BIG/ip helps
us maintain our tough standards for online customer service availability
of REI.com." Coyote Point Systems Adds
Active Content Verification to Equalizer 4.0 A new feature included in 4.0, Active Content Verification (ACV), bypasses misbehaving servers by analyzing the outcome of administrator-configured dialogs for each service. This feature eliminates situations in which servers appear to be up because the hardware and OS remain functional, but the target application is actually down from a practical end-to-end perspective. While other load balancing products (i.e., F5's BIG/ip) also provide
ACV, Coyote Point makes this advanced feature available to the entry-level
market. Equalizer is a price-competitive load balancing solution: a redundant
pair of entry-level E250s can load balance 64 clusters of 8 servers for
just $6,995. For installations involving multiple geographic sites, a
distributed load-balancing add-on (Envoy) is available for $2,495 per
site. Foundy's ServerIronXL Combines
High-Density Gigabit Switch with BigServerIron Load Balancing A member of the IronWare product line, BigServerIron load-balances incoming
traffic through the ServerIronXL. But it returns content directly to the
requesting client, bypassing the switch for higher overall throughput.
While Foundry is not the only vendor to offer this type of load balancing
feature, they do so on switching platform that provides a high level of
system resiliency and port density. The hardware platform, ServerIronXL,
is available with 24 10/100 ports or 8 Gigabit ports for $14,995. Software
infrastructure -- the Management III module -- runs another $26,995. BigServerIron
load-balancing software then tops off the stack at $14,995. Goto page 2: RADWARE's LinkProof Provides Resiliency For Multi-Homed ISPs
