This
high availability (HA) CompactPCI® platform provides a carrier-grade computing
system for demanding mission-critical applications. The ZT 5084 supports five
nines (99.999%) availability with built-in redundancy for active system
components including system-slot CPU boards, power supplies and alarming. These
components are hot-swappable to simplify replacement and minimize service time.
The ZT 5084 platform is ideal for telecom applications requiring high system availability such as enhanced services, media gateway and broadband access servers or any critical computing server platform destined for the central office. The hardware-based failover and simplified HA driver model shorten development time for telecom equipment designers, while redundant system slot architecture enables more efficient use of expensive I/O resources.
Fault tolerance for the ZT 5084 is provided through the use of N+1 redundancy in critical component areas. This fully integrated platform features the software required to meet high system availability metrics, including comprehensive BIOS diagnostics and a development utility to simulate fault conditions and verify system operation.
The two 6U high-availability processor boards feature the Intel® Pentium® III processor - Low Power module, up to 256MB of ECC SDRAM, 512KB of L2 cache, 4MB of flash, onboard 10/100 BASE-T Ethernet and an AGP video controller module. I/O expansion may be accommodated using up-to-two PMC sites (not available in all configurations). Each ZT 5551 High Availability Processor Board is dual redundant, hot-swappable and fills two slots on the CompactPCI backplane.
Of the 16 available backplane slots, four are dedicated to the redundant System Master processor boards (physical slots 7 through 10). Twelve slots support 32- or 64-bit CompactPCI peripheral boards (slots 1 through 6 and 11 through 16). The telephony backplane provides ECTF H.110 computer telephony bus connections across the P4 connectors of all 12 peripheral I/O slots.
Connectors P3 and P5 on each peripheral slot are configured for rear-panel I/O and designed to accommodate IEEE 1101.11-style 80 mm-deep transition boards. Dual CD-ROM drives interface to the processor boards. A hot-swappable five-fan module provides system cooling.
Up to 12 optional Peripheral Master processor boards may be ordered to facilitate a multicomputing environment. Compactnet allows multiple CPU boards, running a variety of operating systems, to coexist on the same backplane. The completely integrated, "network-in-a-box" multicomputing environment increases system performance and consolidates system space by utilizing the CompactPCI bus infrastructure.
System alarm features, built into the ZT 5551 processor board, monitor power supply Degrade (DEG) and Fail (FAL) signals, processor temperature and on-board operating voltages. Critical, major and minor LED indicators and an Alarm Cut-Off (ACO) switch are provided on the front panel of each board. System operating temperatures are independently monitored at several locations at the top of the backplane.
Two ZT 4804 rear panel transition boards provide critical, major and minor LED indicators, an Alarm Cut-Off switch for the system CPU boards and two optically isolated and debounced user inputs. Three pair of dry contact relay outputs provide audible and visual critical, major and minor alarm activation.
Each of the four AC or DC input 150W load-sharing power supplies is diode-protected, hot-swappable and operate together in an N+1 configuration. LEDs indicate over-temperature/current/ voltage and input-present. Fault conditions are sensed by the CPU boards, using the backplane DEG and FAL signals. Total redundant power is 450W (in N+1 configuration). Nominally, 350W is available for peripheral board use.
The ZT 5084 platform features highly integrated software, including a system management driver and development utility, to simplify and speed the development of high-availability solutions. The ability to read, write, query and enable alerts provides for system management data, collected from various locations within the system: SMBIOS table (CPU type, memory size, speed, etc.), redundant CPU events (takeover type, cause, etc.) and SMBus devices (CPU board voltages, temperature, alarm relay status, user inputs, etc.).
The ZT 5551 processor board comes with a user-configurable embedded BIOS to boot an operating system residing in local flash memory, from a fixed or floppy drive, or over a network. It is PC-compatible and supports major operating systems including Windows 2000, VxWorks and Linux. Additional drivers may be available for selected peripherals, flash drives and the SMBus.
The AGP video controller is an optional plug-in mezzanine board. The ZT 5551 processor board is available with support for two PMC locations for mezzanine cards or with one PMC location and one IDE hard drive.
