DEC 3000 AXP

I want to introduct something about Case Storage System. 15 yrs of experiences will assure you the durability, reliability and effectiveness. Case Storage Syst DEC 3000 Model 700 ServerDEC 3000 AXP was the name given to a series of computer workstations and servers, produced from 1992 to around 1995 by Digital Equipment Corporation. The DEC 3000 AXP series formed part of the first generation of computer systems based on the 64-bit Alpha AXP architecture. Supported operating systems for the DEC 3000 AXP series were DEC OSF/1 AXP (later renamed Digital UNIX) and OpenVMS AXP (later renamed OpenVMS).All DEC 3000 AXP models used the DECchip 21064 (EV4) or DECchip 21064A (EV45) processor and inherited various features from the earlier MIPS architecture-based DECstation models, such as the TURBOchannel bus and the I/O subsystem.The DEC 3000 AXP series was superseded in late 1994, with workstation models replaced by the AlphaStation line and server models replaced by the AlphaServer line.Contents1 Models 2 Description 2.1 Memory 2.2 Expansion slots 2.3 Graphics 2.4 I/O subsystem 2.5 SCSI interface 3 Notes 4 References 5 External links // ModelsThere were three DEC 3000 model families, codenamed Pelican, Sandpiper, and Flamingo. Within Digital, this led to the DEC 3000 series being affectionately referred to as "the seabirds".ModelCodenameCPUCPU MHzB-cache (L2)ChassisIntroducedWithdrawnModel 300PelicanEV4150256 KBDesktop1993-04-20?Model 300LPelicaEV4100256 KBDesktop1993-04-201994-03-25Model 300XPelican+EV4175256 KBDesktop1994-02-081995-10-02Model 300LXPelica+EV4125256 KBDesktop1994-02-081995-06-23Model 400SandpiperEV4133512 KBDesktop1992-11-10?Model 500FlamingoEV4150512 KBPedestal1992-11-10?Model 500XHot PinkEV4200512 KBPedestal1993-04-20?Model 600Sandpiper+EV41752 MBDesktop1993-10-131995-10-02Model 700Sandpiper45EV452252 MBDesktop1994-07-211995-10-02Model 800Flamingo IIEV42002 MBPedestal1993-10-131994-02-12Model 900Flamingo 45EV452752 MBPedestal1994-07-211995-10-02Note: Server configurations of the Model 400/500/600/700/800/900 systems were suffixed with "S".DescriptionThe logic in Flamingo- and Sandpiper-based systems are contained on two modules (printed circuit boards), the CPU module and the I/O module, with the CPU module being the largest board. The two modules are connected via a 210-pin connector. The logic in Pelican-based systems are contained the CPU module and system module. The CPU module is a daughterboard that plugs into the system module and contains the CPU and the B-cache (L2 cache).The architecture of the Flamingo- and Sandpiper-based systems is based around a crossbar switch implemented by a ADDR (Address) ASIC, four SLICE (data slice) ASICs and a TC (TURBOchannel) ASIC. These ASICs connect together the various different width buses used in the system, allowing data to be transferred to the different subsystems. PALs were used to implement the control logic. The cache, memory and TURBOchannel controllers, as well as other control logic, is entirely implemented by PALs. Pelican-based systems have an entirely different architecture from the other systems, similar to that of late-model Personal DECstations that they are based on, with a traditional workstation architecture with buses and buffers.MemoryThe Sandpiper and Flamingo used proprietary 100-pin, 40-bit (32 bits plus 8 bits ECC) Fast Page Mode SIMMs with capacities of 2MB, 4MB, 8MB, 16MB or 32MB. These were eight-way interleaved, providing a 256-bit-wide bus to memory. The Sandpiper had two such eight-SIMM banks, for up to 512 MB total system RAM, while the Flamingo had four banks and supported up to 1 GB. In comparison, the Pelican was a budget architecture utilising eight standard 72-pin Fast Page Mode SIMMs that were protected with longword parity instead of ECC, with capacities of 8MB or 32MB, for a total of up to 256MB RAM. These were two-way interleaved, for a 64-bit-wide bus to memory.Expansion slotsThe DEC 3000 AXP series uses the 32-bit TURBOchannel bus running at various speeds, 12.5 MHz in the 300 models, 22.5 MHz in the 400 models and 25 MHz in models 500 to 900. The TURBOchannel bus is provided by an ASIC, which connected it to the SLICE data path ASICs. The number to expansion slots also varied, the 300 models had two slots, except...(and so on) To get More information , you can visit some products about automotive gps system, emergency broadcast system, .
