Caching has evolved over the years, from web caching software running on general-purpose NT or UNIX servers to specialized hardware with cache-tuned operating systems that accelerate delivery of many content types. In this, the first in a planned series of six cache reviews [see overview], we take a hands-on look at one of the next generation of caches: the Quantex WebXL. WebXL is a turnkey cache appliance designed for rapid deployment in small-to-medium size ISP and enterprise environments.
Under the Covers
At the heart of WebXL lies the Novell Internet Caching System (NICS) and its patent-pending Cache Object Store. Quantex joins Compaq, Dell, Pionex, and MICROBITS as an OEM distributor for NICS; each manufacturer adds its own unique hardware, packaging, documentation, support, and pricing spin when producing a NICS-based product.
We evaluated the WebXL 2000, sized to cache one million objects at an entry-level price of $3,999. The 2000 includes 250MB RAM, 10GB HDD, and dual 10/100 Ethernets. Big brother WebXL 3000 doubles capacity and adds high-availability features (third Ethernet, disk cloning, and disk mirroring) for $7,499. The upcoming WebXL 4000 will add hot-swappable drives and power supplies. There is no provision for integrating external storage.
