ES7000

The ES7000, is Unisys's current Intel/Windows and Linux-based server product line [ [http://www.unisys.com/products/enterprise__servers/high_d_end__servers/index.htm Unisys | High End Enterprise Servers | IT Infrastructure Solutions ] ] . The family of servers is generically referred to as the "ES7000" although variants and models within the family support various processor and bus architectures. The server is marketed and positioned as a scale-up platform where scale-out becomes inefficient. Typically the ES7000 was utilized as a platform for homogeneous consolidation, large databases (SQL Server and Oracle), Decision Support Systems, ERP, and recently large Linux application hosting.

The hardware and software elements of the server are monitored by a software suite known as Server Sentinel.

Architecture

Elements of the ES7000 architecture includes
* Multiple power domains
* N+1 redundancy for most components
* Subpod CPU scaling (4 cpu increment)
* Centralized memory/cache control
* Shared cache
* Point to point crossbar connections (fleXbar) among memory, processors, and I/O components
* Multiple I/O PCI bridges and buses
* Up to 8 direct I/O bridges each providing 3 independent PCI buses, supporting 96 PCI slots (On 100 and 200 series)
* Multiple memory storage units that can be combined or used separately

History

This server family has undergone several model revisions in its lifetime since 1999. Initially, the servers were standalone -- physically the configuration resembled a rack and took up a somewhat larger footprint than a rack (Models 100, 130, 200, 230, 550, 400). Second and third generation ES7000s were rack mountable cells 4U or 3U high that fit in standard 19" racks.

Form Factors

The ES7000 models are broken down into three form factors.

* Cabinet/Frame size (A monolithic, midpane architecture, but deeper than a conventional rack)
* 4U Size Cell with up to 8 processors per cell and 8 PCI slots, up to four cells can be bound together to create a 32 cpu system)
* 3U Size Cell with up to 4 processor sockets per cell and 5 PCI slots, up to eight cells can be strapped together to create a 32 socket system)

Processors

The processors used in the ES7000 are:

* Intel Xeon
* Intel Multicore Xeon
* Intel Itanium and Itanium 2

Operating Systems Supported

* Windows: 2003 and Windows 2008
* Linux: SuSe and RedHat
* VMware: ESX 3.02 and ESX 3.5

Features

ES7000 Servers generally support the Microsoft Windows operating system both 32-bit Xeon and 64-bit Itanium, and recently the 32-bit and 64-bit versions of some Linux operating systems.
