Introduction Extensions and conversions
1.2 Extensions and conversions
The PRIMERGY RX100 S4 server is offered in a SATA and a SAS version. The
versions differ in the chipset assembling of the system board and in the config-
uration of the hard disks.
Extension of the main memory
The four slots for the main memory are suitable for unbuffered DDR II 533
(PC2-4200) SDRAM memory modules. The organization in two memory banks,
1 and 2, permits rapid memory access with two-way interleaving.
If the memory modules are populated in pairs, each pair must consist of
identical memory modules (2-way interleaved mode).
Additional accessible drive
One 5.25-inch slimline bay is available for accessible drives.
Additional non-hot-plug SATA hard disk drive
(only SATA version)
A second bay is available for non-hot-plug SATA hard disk drives.
Additional controllers in the PCI slots
The system board offers 2 x PCI-X (64 Bit / 133 MHz) or 1x PCI-Express x8 and
2 x PCI-X (64 Bit / 133 MHz) slots by a riser card.
Upgrading non-hot-plug variant to hot-plug variant
(only SATA version)
The non-hot-plug variant can be upgraded to a hot-plug variant by installing a
SAS/SATA backplane and inserting hot-plug SATA hard disks.
