BX620 S4
Operating Manual

Introduction
Features
The hard disk modules can be replaced or added while the system is running
(hot-plug), without having to take off the server blade cover. How to
install/replace hard disk modules is described in
chapter “Hot-Plug Compo-
nents” on page 65
.
Storage Modules
The hard disks are controlled by a storage module (controller) that can be
plugged into the motherboard and which may also have additional functions.
SATA only offers one storage module variant, while SAS offers a total of four
different variants: SAS, SAS/MegaRAID, SAS/PCI-X and SAS/PCIe. The two
PCI variants allow the installation of low-profile PCI modules.
Storage modules can be installed/replaced via the front of the server blade,
without having to take off the housing cover. However, they cannot be replaced
while the system is running (non-hot-plug) - the server blade must be switched
off.
How to install/replace storage modules is described in the Options Guide.
LAN Availability
The BX620 S4 Server Blade has three onboard LAN controllers with TOE and
iSCSI functionality each with two 1-Gbit/s Ethernet channels. The Ethernet LAN
connection can be implemented via switch blades or via pass-thru blades on the
back of the PRIMERGY BX600 S2 or BX600 S3 basic unit. For more information
see the Operating Manual for the basic unit.
Optional Fibre Channel or Ethernet I/O Module (daughter card)
The BX620 S4 Server Blade can be equipped with an I/O daughter card for the
connection to a SAN or for additional Ethernet connections.
The following I/O daughter cards are available:
–
2-Gbit/s Fibre Channel I/O module with an onboard QLogic ISP2312 chip,
compatible with Qlogic QLA2342; supports several FC storage subsystems
with the corresponding versions.
