Systems

Step 1 - Requirements

Step 1a - System Requirements

Mandatory Purchases: The system cannot function without these options or services - the option or service must be ordered with the system. Base System (Step 2) Dual CPU Building Block Modules (Step 3) Memory (Step 4) Master I/O Building Block Drawer (Step 5) Power Distribution Unit(s) (Step 6) Optional Purchases: I/O Building Block Drawer(s) (Step 5) System disk(s) (Step 5) Dual AC Power (Step 7) Internal System Expansion (Step 8) External Rack Expansion - (Step 9) Other (see ES/GS Common Options) Recommended Services: HP Care Pack Service Package (see ES/GS Common Options - Step 12)

Step 1b - Requirements for Partitions

A single AlphaServer GS1280 can be divided into logical hardware partitions as small as two processors, each running an instance of Tru64 UNIX or an instance of OpenVMS. Each partition is allocated its own dedicated "shared-nothing" set of hardware resources: CPU module(s), memory module(s), and I/O. Each hardware partition is viewed as a unique node, from a system point-of-view, with its own instance of Tru64 UNIX or OpenVMS operating system and application software, independent system console, and error log.

Minimum Hardware and Software Required per Hardware Partition

One Dual CPU Building Block Module (Step 3) Memory (Step 4) I/O Drawer (Step 5) One Standard I/O Drawer (Master or Expansion), or Shared (up to four hard partitions) access to one High Performance I/O Drawer (Master or Expansion) One local disk (Step 5) or external storage for the system software. Network boot can be used in place of the disk storage. User access via the USB port in a Master I/O Drawer, a network connection (requires a LAN or WAN I/O adapter), or local terminal (requires an async I/O adapter). All systems require the following minimum firmware and software revisions to run hard partitions: Minimum Firmware console rev: V6.5-8 Tru64 UNIX: V5.1B + Patch kit - T64V51BB22AS0002-20030415.tar OpenVMS: V7.3-1 + TIMA Kits (available at http://h18003.www1.hp.com/alphaserver/gs1280/gs1280_tech.html): DEC-AVPVMS-VMS731_PARTITIONING-V0100-4.PCSI AVPVMS-VMS731_PARTITIONING-V0100_cVRLET AVPVMS-VMS731_PARTITIONING-V0100_SUBFORM

Configuration Guidelines

The two processors on a Dual Processor CPU Module cannot be split between hard partitions. The set of processors assigned to a partition must form a continuous rectangle on the system interconnect mesh network. CPU modules in an 8P Building Block Drawer share the same 48v power feed (from a redundant power supply). If the 8P Building Block Drawer contains all or portions of several hard partitions, a power fault in the drawer could affect all the partitions in that drawer. Hard partitions that consist of whole 8P Building Block Drawers limit the risk of a power fault in one drawer to one partition. Base systems include an operating system license (Tru64 UNIX or OpenVMS) that licenses all hardware partitions of the system. The license for an HP software product, the license(s) and license key(s) that represent those licenses, may be applied to any partition (OpenVMS Galaxy instance or hardware partition) within that system. Different versions of the operating system or layered products may be used on different partitions. In this case, the customer must be licensed for the latest version in use. Software products from other suppliers may have different licensing requirements for partitions.

Step 1c - Licensing Systems for Both OpenVMS and Tru64 UNIX

A System requires licenses for both OpenVMS and Tru64 UNIX operating systems, either for dual O/S boot of the entire system or for different operating systems in separate hard partitions. To use a second operating system, order the appropriate base system upgrade license and as many dual CPU SMP licenses as needed.
	OpenVMS software base system upgrade for GS1280	QB-63PAQ-AC
	Tru64 UNIX software base system upgrade for GS1280	QB-595AN-AB
	OpenVMS Alpha dual CPU SMP license for GS1280	QL-MT1A9-6T
	Tru64 UNIX Alpha dual CPU SMP license for GS1280	QL-MT4A9-6T

Step 1d - System Management Hardware/Software Requirements

Each AlphaServer ES47, ES80, and GS1280 system includes System Management software that can significantly enhance and simplify monitoring and control of the system. Use of the System Management software is optional. The software, which runs on a separate Intel or Alpha system, consists of two major components: Alpha Management Station (AMS) - for monitoring and control of multiple ES47, ES80, and GS1280 Alpha Systems. AMS offers the highest level of server management functionality for a single or multi-platform environment. The AMS software requires the following hardware in order to operate: Tru64 UNIX platform with 512-MB memory, 4-GB disk space, and two network interface cards running Tru64 UNIX V5.1B or later. Intel IA-32 platform running Linux, 500-MHz CPU or faster, 256-MB memory, 4-GB disk space, and one network interface card. Alpha Management Utility (AMU) - for monitoring and control of a single ES47, ES80, or GS1280 Alpha System. The AMU is a GUI based application that provides a sophisticated, yet user-friendly graphics interface. The AMU is a Web-based utility, which allows a user local and remote access from a browser. The AMU software requires one of the following hardware platforms in order to operate: Intel IA-32 platform running Windows 2000 or later, 500-MHz CPU or faster, 256-MB memory, 4-GB disk space, and one network interface card. Intel IA-32 platform running Linux, 500-MHz CPU or faster, 256-GB memory, 4-GB disk space, and one network interface card. Tru64 UNIX platform running V5.1B or later, 512-MB memory, 4-GB disk space, and one network interface card. OpenVMS platform running V7.3-1 or later, 512-MB memory, 4-GB disk space, and one network interface card. Both the AMS and AMU software require Internet Explorer 5.5 or later or Netscape 4.76 or later. AMS/AMU software kits and instructions may be downloaded from: http://ftp.digital.com/pub/Digital/Alpha/firmware/interim/ams/index.html

Step 2 - Select Base System - Mandatory
Mandatory selection of at least one Base System required.

Configuration Guidelines CPU Building Blocks with different clock speeds can co-exist in one system, but must be separated into hard partitions where the CPUs have the same speed. CPU Building Block or instant Capacity (iCAP) CPU Building Block Modules type (Tru64 UNIX or OpenVMS) must match the base system operating system selected in Step 2, or purchase a base operating system upgrade license to match the license with the CPU Building Block Module.

Configuration and Use of instant Capacity (iCAP) CPUs

The instant Capacity (iCAP) program gives HP customers the option to purchase add-on CPU modules at a reduced price and install those modules in systems ready to activate instantly when needed for extra computational capacity. To use the iCAP program for AlphaServers:

Order and install iCAP CPU modules along with Full Use CPUs. The total number of Full Use CPU Building Block Modules plus iCAP CPU Building Bock Modules must adhere to the limits outlined above for GS1280 systems.
Use the iCAP software (supplied with the iCAP CPU Module) to set iCAP CPUs inactive. As long as the total number of active CPUs does not exceed the number of licensed CPUs owned for the system, the owner may choose which CPUs to designate as iCAP.
Inactive iCAP CPUs cannot include the primary CPU, CPUs responsible for hardware interrupts, CPUs being used by an application when configuring iCAP, or a CPU connected to an I/O Building Block Drawer.
Activate the iCAP CPUs for First Use when extra capacity is needed, and then promptly purchase the iCAP Enablement (Right-to-Use).

iCAP CPU Building Block Module + iCAP Enablement = Full Use CPU Building Block Module

TERMS and DEFINITIONS
iCAP CPU MODULE	AlphaServer CPU add-on module including the OpenVMS SMP or Tru64 Unix SMP extension license, end user product warranty, iCAP software, plus limited Rights-to-Access the CPU module and leave inactive until First Use.
FIRST USE	First Use takes place when one or more processors on the iCAP CPU Module are activated for permanent use. Temporary replacement of a failed CPU with an iCAP CPU does not constitute First Use. Activation of an iCAP CPU after deactivation of a full use CPU does not constitute First Use. For example, owners are permitted to deactivate a Full Use CPU in one hard partition of the system and activate an iCAP CPU in another hard partition without First Use of the iCAP CPU. First Use of an iCAP CPU Module is considered to have taken place only when the number of active CPUs in the system is greater than the number of purchased full use CPUs.
iCAP ENABLEMENT	Grants full Right-to-Use for a previously purchased iCAP CPU Module.
PROGRAM PERIOD	There is no time limit to activate an iCAP CPU.

GS Options

Step 4 - Select Memory Options - Mandatory

Configuration Guidelines
Mandatory selection of one memory option per CPU (two memory options per Dual CPU Building Block Module). Optional selection of a second memory option for each CPU. Both options must be the same size and speed for a CPU, but different size options can be used on different CPUs. Each memory option consists of four RDRAM Inline Memory Modules (RIMMs). An optional fifth RIMM (RAID option) may be selected for redundancy that will allow uninterrupted operation in case of the loss of an entire RIMM. RAID options must be selected and matched for each memory option on one CPU, but RAID options do not have to be selected for all CPUs.
NOTE: Memory must be ordered for iCAP CPU Modules as well as Full Use CPU Modules. The system will use memory installed on the iCAP CPU Module even when the iCAP CPU is inactive.

Memory Application Examples
The following examples illustrate different ways of configuring one 8P System Building Block Drawer with eight CPUs and a total of 16 GB of memory.

		CPU Building Block Module #1				CPU Building Block Module #2
Case	Memory Option	CPU 1		CPU 2		CPU 3		CPU 4
Case	Memory Option	Controller 1	Controller 2	Controller 1	Controller 2	Controller 1	Controller 2	Controller 1	Controller 2
A	3X-MS7AB-BA (4 x 256 MB)	1	1	1	1	1	1	1	1
B	3X-MS7AB-CA (4 x 512 MB)	1	-	1	-	1	-	1	-

		CPU Building Block Module #3				CPU Building Block Module #4
		CPU 5		CPU 6		CPU 7		CPU 8
		Controller 1	Controller 2	Controller 1	Controller 2	Controller 1	Controller 2	Controller 1	Controller 2
A	3X-MS7AB-BA (4 x 256 MB)	1	1	1	1	1	1	1	1
B	3X-MS7AB-CA (4 x 512 MB)	1	-	1	-	1	-	1	-

Configuring memory is a compromise between cost, total memory capacity, and memory bandwidth requirements. The following may be used as guidelines: Applications, in which large amounts of memory can substantially reduce I/O throughput, may be optimized for total memory capacity and future capacity growth. (Case B) Typical commercial applications, such as transaction processing (OLTP) and multi-user timesharing, usually operate efficiently from cache and may not be materially affected by memory bandwidth. Memory configuration is a balance between memory bandwidth and future capacity growth. (Case B) Data mining can benefit from additional memory bandwidth. It is best to match the number of memory base modules to the number of CPUs. (Case A) The most demanding high-performance technical applications achieve a performance level that is directly proportional to memory bandwidth. In these cases, configure two memory options per CPU. (Case A)
Memory Specification		800 MHz	1066 MHz
Use only with the indicated CPU Modules (mandatory)		Must be used only with EV7 1.15 GHz (3X-KN72C-**)	May be used with either EV7 1.3 GHz (3X-KN72D-) or EV7 1.15 GHz (3X-KN72C-)

Step 5 - System I/O Expansion - Mandatory

Configuration Guidelines
Each AlphaServer GS1280 system requires one I/O Master Building Block Drawer per system. Additional I/O Building Block Drawers are optional. Each additional hard partition in the system requires: One Standard I/O Drawer (Master or Expansion), or Shared (up to four hard partitions) access to one High Performance I/O Drawer (Master or Expansion) Each CPU in a GS1280 System Building Block Drawer can provide one I/O connection to an I/O Drawer. Either a Standard I/O Drawer (Expansion or Master) or High Performance I/O Drawer (Expansion or Master) can be used for optional I/O expansion. Any combination of drawers is supported up to the I/O connection limit of 32 per hard partition or 64 per system with 2 or more hard partitions. The Standard I/O Drawer requires one I/O connection. The High Performance I/O Drawer requires one and optionally up to four connections.
Example - AlphaServer GS1280 Model 16 with 12 processors

	Twelve Processors, one I/O connection each	=12 I/O connections available
	Six Standard I/O Drawers, one I/O connection each	= 6 I/O connections
	One High Performance I/O Drawer with four I/O connections	= 4 I/O connections
	One High Performance I/O Drawer with two I/O connections	= 2 I/O connections
	Total I/O Drawer Connections	=12 I/O connections used

	I/O Module for Connection to CPU in a System Building Block Drawer	I/O Buses	I/O Slots	Dual Redundant Power Supplies	USB/ Ultra3 SCSI Adapter Card	DVD/ CD-RW Drive	Universal Slot for Disks	Part Number

High Performance I/O Drawer, Master	1 standard 3 additional, optional ¹	2 to 8 PCI-X	2 to 8 PCI-X	Yes	1 in PCI-X Slot	1	2⁴	3X-BA70B-AA

Add-in I/O Module for High Performance I/O Drawers. Each module supports two PCI-X slots. Up to three modules may be added to the base High Performance I/O Drawer.	3X-KFMHA-AA
I/O 3.3-meter cable for connection between GS1280 System Building Block Drawer and I/O Building Block Drawers mounted in a system rack or adjacent expansion rack; select one cable for each I/O drawer ordered and one cable per Add-in I/O Module (3X-KFMHA-AA) if ordered.	3X-BNPSA-04
I/O 4.5-meter cable for connection spanning one or two racks between GS1280 System Building Block Drawer and I/O Building Block Drawer mounted in an expansion rack; select one cable for each I/O drawer ordered and one cable per Add-in I/O Module (3X-KFMHA-AA) if ordered.	3X-BNPSA-05
I/O 6.0-meter cable for connection spanning three racks between GS1280 System Building Block Drawer and I/O Building Block Drawer mounted in an expansion rack; select one cable for each I/O drawer ordered and one cable per Add-in I/O Module (3X-KFMHA-AA) if ordered.	3X-BNPSA-06
NOTES: One High Performance I/O Drawer can be used by up to four separate hard partitions. Each of the four I/O connections (and two associated PCI-X slots) in the High Performance I/O Drawer can be independently controlled (e.g. power on/off) in conjunction with a separate partition. A Master I/O Drawer consists of a Standard or High Performance I/O Drawer plus a Combination Adapter in one slot. The Combination Adapter provides an Ultra3 SCSI connection for two disks and a DVD/CD-RW drive in the drawer, plus a USB connection for keyboard, mouse, and monitor. The Master I/O Drawer is required for all GS1280 systems integrated at the manufacturing plant by HP. If the final system configuration does not require these I/O devices, the Combination Adapter may be removed and replaced with the following alternatives: System Boot - External storage or network boot can be used in place of the disk storage internal to the I/O Drawer. Software Load - Software can be loaded over the network from a disk on another system or directly from a CD reader attached to another system by using remote mount. User I/O - User access via a network connection can be used in place of the direct connection via the USB port. The two disks in the Master I/O Drawer can only be connected to the system via the Combination Adapter's Ultra3 SCSI connection. The I/O Drawer design does not permit connection from other storage adapters, such as a RAID adapter, that might be installed in the I/O Drawer. Each Master I/O Drawer supports up to two, optional, hard disk drives. See the Disks step of the ES/GS Common Options section of this QuickSpec for the selection of supported disk drives.

Step 6 - Power Distribution Units - Mandatory

			GS1280 Model 8	GS1280 Model 16	GS1280 Model 32	GS1280 Model 64
			DA/DY-1280A-AA	DA/DY-1280A-BA	DA/DY-1280A-CC	DA/DY-1280A-BD
Type A Power Distribution Units Select one variant.	North America/Japan 200 -208V, NEMA L21-30P 30A; 3 x C19 outlets plus 24 x C13 outlets	3X-H7606-AA	1 required (provides receptacles for power cords from all system components)	2 required (provides receptacles for power cords from all system components)	2 required (provides receptacles for power cords from I/O Drawers, LAN Hub, and storage shelves)	2 required (provides receptacles for power cords from I/O Drawers, LAN Hub, and storage shelves)
	International 380/415V Y, IEC 309 32A; 3 x C19 outlets plus 24 x C13 outlets	3X-H7606-AB
Type B Power Distribution Units Select one variant.	North America/Japan 200 - 208V, IEC 309 60A	3X-H7606-BA	Not applicable	Not applicable	2 required (for M32/M64 Dual AC power supply exclusively for 8P system drawers)	4 required (for M32/M64 Dual AC power supply exclusively for 8P system drawers)
	International 380/415V Y, IEC 309 32A	3X-H7606-BB
NOTES: Select the same power supply voltage variant for both Type A and Type B Power Distribution Units, e.g. both 200-208V or both 380/415V. IEC 309 is a general spec that can encompass 3 different pin types. The 3X-H7606-BA PDU uses the Hubbell 460P9W, a 4 pin connector. The 3X-H7606-AA PDU uses an L21-30P 30 amp plug, Hubbell 2811, a 4 pin connector.

Step 7 - Dual AC Power - Optional

A Dual AC power option provides the capability to connect to two separate AC feeds: a primary AC feed and a secondary AC feed. The feeds can be direct from the power utility, or they can be a combination of utility feeds and UPS or generator feeds. The preferred (primary) feed is determined by the user. In the event of failure of the primary feed, the system will automatically transfer the load to the secondary feed without power interruption.

Reference 1 – I/O Capacity for AlphaServer ES47/ES80 and AlphaServer GS1280 Systems

AlphaServer ES47/ES80 and GS1280 systems offer three types of I/O bus standards for adapters and controllers.

1.	PCI-X — Peripheral Component Interconnect Extended is a computer bus interface standard for connecting a microprocessor and attached devices. PCI-X doubles the speed and amount of data exchanged between the computer processor and peripherals from the predecessor PCI bus. PCI-X is backwards-compatible, meaning that users can, for example, install a PCI-X card in a standard PCI slot but expect a decrease in speed to 66 MHz or 33 MHz. Users can also use both PCI and PCI-X cards on the same PCI-X bus, but the bus will run at the speed of the slowest card. PCI-X is more fault tolerant than PCI. For example, PCI-X is able to reinitialize a faulty card or take it offline before computer failure occurs.
2.	PCI — Peripheral Component Interconnect is a computer bus interface standard for connecting a microprocessor and attached devices.
3.	AGP 4 — Accelerated Graphics Port (AGP) is an interface specification that enables 3-D graphics to display quickly. It is especially useful in conjunction with three-dimensional (3D) video, and sophisticated scientific and engineering graphics programs. AGP runs at several times the bus speed of conventional Peripheral Component Interconnect (PCI). Because of this, the data transfer rate using AGP is significantly greater than with PCI video cards. The AGP 4X mode provides high performance levels with a peak bandwidth of 1066 MB/s. AGP 4X mode is a superset to the 1X and 2X modes; thus, all components supporting AGP 4X must also support 1X and 2X modes.

The following table presents the matrix of maximum, theoretical I/O throughput for the different standards. Actual I/O throughput will be less than calculated because of protocol overhead and contention for bus capacity.

Calculated Maximum Throughput	32-bit data path	64-bit data path
PCI, 33 MHz	0.133 GB/s	0.267 GB/s
PCI or PCI-X, 66 MHz	0.267 GB/s	0.533 GB/s
PCI-X, 100 MHz	N/A	0.8 GB/s
PCI-X, 133 MHz	N/A	1.067 GB/s

I/O for Two-processor System Building Block Drawer used in ES47 and ES80 Systems

For PCI-X capable slots: All universal or 3.3V PCI and PCI-X cards are supported, EXCEPT: UltraSCSI wide differential adapter, 32-bit/33-MHz PCI adapter (3X-KZPBA-CC) PCI-X protocol is used on the bus, but reverts to PCI protocol in these cases: When one or more PCI cards are in a bus segment Gigabit Ethernet, Rev A (DEGXA-SA/TA) is in the bus segment An I/O bus segment will operate at the least common denominator of the adapters installed or the lower speeds dictated by bus loading (as shown in the tables), whichever is less. The PCI-X card slots must be populated contiguously starting with slot 1; otherwise the bus will run at 33 MHz PCI.
