Table 1. Standard specifications (part 1)
Components Specification
Model numbers IBM Flex System p24L Compute Node: 1457-7FL
IBM Flex System p260 Compute Node: 7895-22X, 23A, and 23X
IBM Flex System p460 Compute Node: 7895-42X and 43X.
Form factor p24L: Standard-width compute node.
p260: Standard-width compute node.
p460: Double-width compute node.
Chassis support IBM Flex System Enterprise Chassis.
Processor p24L: Two IBM POWER7 processors
p260: Two IBM POWER7 (model 22X) or (models 23A and 23X) processors.
p460: Four IBM POWER7 (model 42X) or (model 43X) processors.
POWER7 processors: Each processor is a single-chip module (SCM) that contains either eight
cores (up to 3.55 GHz and 32 MB L3 cache) or four cores (3.3 GHz and 16 MB L3 cache). Each
processor has 4 MB L3 cache per core. Integrated memory controller in each processor, each
with four memory channels. Each memory channel operates at 6.4 Gbps. There is one GX++
I/O bus connection per processor. Supports SMT4 mode, which enables four instruction threads
to run simultaneously per core. Uses 45 nm fabrication technology.
processors: Each processor is a single-chip module (SCM) that contains either eight
cores (up to 4.1 GHz or 3.6 GHz and 80 MB L3 cache) , four cores (4.0 GHz and 40 MB L3
cache) or two cores (4.0 GHz and 20 MB L3 cache). Each processor has 10 MB L3 cache per
core. There is an integrated memory controller in each processor, each with four memory
channels. Each memory channel operates at 6.4 Gbps. There is one GX++ I/O bus connection
per processor. Supports SMT4 mode, which enables four instruction threads to run
simultaneously per core. Uses 32 nm fabrication technology.
Chipset IBM P7IOC I/O hub.
Memory p24L: 16 DIMM sockets
p260: 16 DIMM sockets.
p460: 32 DIMM sockets.
RDIMM DDR3 memory supported. Integrated memory controller in each processor, each with
four memory channels. Supports Active Memory Expansion with AIX 6.1 or later. All DIMMs
operate at 1066 MHz. Both LP (low profile) and VLP (very low profile) DIMMs supported,
although only VLP DIMMs are supported if internal HDDs are configured. The use of 1.8-inch
solid-state drives allows the use of LP and VLP DIMMs.
Memory
maximums
p24L: 512 GB using 16x 32 GB DIMMs.
p260: 512 GB using 16x 32 GB DIMMs.
p460: 1 TB using 32x 32 GB DIMMs.
Memory
protection
ECC, chipkill.
Disk drive bays Two 2.5-inch non-hot-swap drive bays supporting 2.5-inch SAS HDD or 1.8-inch SATA SSD
drives. If LP DIMMs are installed, then only 1.8-inch SSDs are supported. If VLP DIMMs are
installed, then both HDDs and SSDs are supported. An HDD and an SSD cannot be installed
together.
Maximum
internal storage
1.8 TB using two 900 GB SAS HDD drives, or 354 GB using two 177 GB SSD drives.
