Technology Overview
Mac OS X Server
Xgrid. Mac OS X Server v10.4 includes Xgrid, the rst distributed computing architec-
ture to be built into a desktop or server operating system. Xgrid makes it easy to
turn an ad hoc group of Mac systems into a low-cost supercomputer by streamlining
the process of assembling nodes, submitting jobs, and retrieving results. Scientists,
animators, and digital content creators now have the opportunity to easily run a
single job across multiple computers at once, dramatically improving performance
and responsiveness.
Ethernet link aggregation and network interface failover. Also known as IEEE
802.3ad, link aggregation allows you to con gure multiple network interfaces to
appear as a single interface, which can increase throughput and availability. First, link
aggregation multiplies the potential I/O performance by the number of interfaces.
For example, two 1-gigabit interfaces bonded together can provide up to 2 gigabits
of aggregate network bandwidth, and four 1-gigabit interfaces can provide up to
4 gigabits. Second, link aggregation eliminates a potential single point of failure. If
one interface fails, the remaining interface maintains the network connection.
Gateway Setup Assistant. The new Gateway Setup Assistant helps you quickly and
easily set up Mac OS X Server v10.4 to share a single Internet connection across a
local network. The assistant eliminates the complexity of setting up network services
by automating the process. All you have to do is make a few con guration choices
when prompted.
Adaptive junk mail ltering and virus detection. To protect your organization from
unwanted mail and destructive viruses, Mac OS X Server v10.4 integrates two popular
open source projects: SpamAssassin for adaptive junk mail ltering, and ClamAV for
virus detection and quarantine.
