Sun Microsystems, Inc. Netra 240 Server Architecture P7 Front Access Normal operations in a deployed environment typically involve, at some point, tasks such as putting a server in standby mode, swapping a hard disk drive, or re-configuring the system. With the Netra 240 server, administra- tors can accomplish such tasks through a push button switch, a rotary switch, and a System Configuration card— all accessible behind the front bezel. Administrators can access these simple-to-use features by

This approach minimizes J-Bus transactions for I/O and enhances performance for I/O access to main memory. In addition, the JIO Hostbridge ASICs support PCI DMA write and read bursts of 1 KB (32-bit PCI) and 2 KB (64-bit PCI) with no disconnect. 64-bit PCI DMA writes execute at peak PCI bus throughput. Each of the two JIO Hostbridge ASICs provides two 64-bit interfaces (one at 33
