The IBM Flex System p260 Compute Node or IBM Flex System p460 Compute Node is based on IBM POWER® technologies. These compute nodes run in IBM Flex System Enterprise Chassis units to provide a high-density, high-performance compute-node environment with advanced processing technology.

Description:

IBM P260 7895-23X 32GB DIMM EM4D 

Features:

The IBM Flex System p260 Compute Node is a one-bay compute node and is used in an IBM Flex System Enterprise Chassis. The p260 compute node is a half-wide node. Up to 14 p260 nodes can be configured into each 10-U Flex System Enterprise Chassis.  The following options are available for the p260 compute node:

The p260 compute node has two processor sockets and both must be filled with one of the following combinations:

• 2 x 3.3 GHz 4-core (total of 8 cores)
• 2 x 3.3 GHZ 8-core (total of 16 cores)
• 2 x 3.55 GHz 8-core (total of 16 cores)

Available Memory Features

• 16 DIMM slots
• Low profile (LP) memory DIMMs in 2 GB and 16 GB sizes
• Very low profile (VLP) memory DIMMs in 4 GB and 8 GB sizes
• Orderable memory in DIMM pair increments
• Maximum configurable memory of 256 GB

Internal Disk Bays

• Two, optional internal disk bays, which share a single, SAS controller, are available.
• Internal disk bays support either SAS HDD or SAS SSD.
• Disk drives are not hot-swappable.
• HDD and SSD devices can’t be intermixed.
• HDDs are only supported with VLP memory DIMMs (4 GB and 8 GB).
• HDDs operate at 10K RPM and are available in 300, 600, and 900 GB sizes.
• SDD is available in 177 GB size and can be configured with LP or VLP memory DIMMs.

The disk drives are housed underneath the top cover of the node. One of the following options must be configured with each p260 node:

1. Two HDD connectors
2. Two SSD connectors
3. No drive connectors

I/O Adapters

The following adapters can be used with the p260 compute node’s two I/O adapter slots:

• 4-port 10 Gb Ethernet
• 4-port 1 Gb Ethernet
• 2-port 8Gb FC
• 2-port QDR Infiniband

The first adapter slot must contain a 10 Gb or 1 GB Ethernet adapter; no customer useable integrated Ethernet ports are available. The only integrated network interface is reserved for exclusive use by the service processor. The 8Gb FC adapter supports N-Port ID virtualization (NPIV).

Additional p260 Features

Current Power Systems users will recognize many of the following features, which can be ordered on the p260 compute node:

• Factory de-configuration of processor cores can be used to reduce OS and PowerVM licensing and software maintenance (SWMA) charges.
• Active Memory Expansion is designed to improve memory utilization.
• Support for up to 10 virtual servers per configured core is available.
• The available PowerVM Edition includes: Express, Standard and Enterprise. With the Standard and Enterprise edition, up to 10 virtual servers can be configured per core.
• IBM i 7.1 and 6.1, AIX 7.1 and 6.1 and Linux (Red Hat and SUSE) are supported.

Virtualization Considerations

Virtualized network and disk virtualized are supported using a single PowerVM Virtual I/O (VIO) server. Adapter-allocation rules are similar to Power Systems servers. All ports associated with an adapter card are allocated to a single virtual server.

The maximum configuration for the p260 compute node is one 4-port Ethernet adapter and one 2-port 8 Gb FC adapter. Both of these adapters can be configured to create a single VIO server-based system. When configured with internal HDDs or SDDs, both drives are connected to a single SAS controller that can be allocated to a single virtual server or VIO server. Note that the Integrated Virtualization Manager (IVM) isn’t supported with the p260 compute node.
