HDS-C overview

1 HDS-C overviewMain functions of HDS-CHard Disk SAS Variant C (HDS-C) is a mass memory plug-in unit which is used to imple-ment a non-volatile memory for program code and data in RNC. HDS-C connects to the OMU via the PCI-E link.

Operating environment of HDS-CThe HDS-C plug-in unit works with the OMU units. The computer unit serves one PCI-E link which connects to the HDS-C through the external cable. The HDS-C has two SAS ports, one connects to the Hard Disk Drive (HDD) on the HDS-C unit, and the other to the HDD on the redundant HDS-C unit.

The HDS-C plug-in unit is connected to the hardware management bus via the bus inter-face of the HMSS. HDS-C has a service terminal interface via the back connector.

The HMSS has a separate power feed in 2N redundancy.

The HDS-C gets -48 V DC supply and 5.35 V HMSS power from the back connectors. The operational environment of HDS-C is shown in Figure 1 Operational environment of the HDS-C.

3.1 Mechanical structure of HDS-C and HDD tray

3.1.1 Mechanical structure of HDS-CThe HDS-C plug-in unit is implemented with a single standard IPA2800 full size printed wiring board (PWB). The size of the PWB is 265 mm by 287.3 mm (height x length). The nominal thickness of the board is 2.0 mm.

The front panel is connected to the PWB using 6 screws (M2.5X6). There are two holes for the LED-PIPEs, one mini-SAS connector, one QSFP connector and one HDD tray on the front panel.

There are two HDD tray guides at the PWB for HDD tray installation. The HDD tray guides are connected to the PWB with screws. A stiffener is connected with screws to the PWB to strengthen the HDD tray guides. The HDD is installed to the HDD tray, which is then installed to the HDD tray guides.

There are three different power voltages in HDS-C:

HDD: +12 V and +5 V HMSS: +5.35 VFigure 2 HDS-C layout shows the HDS-C layout with the HDD tray uninstalled:

3.1.2 Mechanical structure of HDD trayThe size of the HDD tray is 98 mm x 142.7 mm (height x length).The size of the HDD tray front panel is 114 mm by 25 mm (height x width). The front panel includes two PF11 screws and two EMC gaskets. There are two holes for the LEDs on the front panel, and the LEDs connect with the HDD tray PWB through LED cables.

The HDD tray is connected to the HDS-C PWB with two connectors: one is Tinman con-nector for high speed data transfer, and the other is for power supply. The HDD is con-nected to the HDD tray using the SAS connector and fastened to the HDD tray with screws.

The layout of the HDD tray with the installed HDD is shown in Figure 3 HDD tray layout.

Figure 4 Block diagram of HDS-C

HDD blockHDD provides an interface to the SAS controller, which then serves as the interfaces to OMU and the other HDD on the redundant HDS-C unit.

HMSS node blockThe Hardware Management System Slave node provides an interface to the Hardware Management System. HMS slave node collects alarm information and the node is also used for diagnosis.

The Hardware Management System has its own bus so it is not dependent on the ATM-based messaging. It has its own power supply, which is separate from the plug-in unit's power supply. This is because the Hardware Management System has to remain oper-ational even if normal messaging and/or power distribution fails.

Power blockThere is a power unit (DC/ DC converter) integrated in the HDS-C unit. It receives -48 V voltage from the backplane connector and generates the voltages in 5 V and 12 V for the hard drive.

The HMSS node has its own power supply which is independent to the power supply of the plug-in unit. The power supply of the plug-in unit can be turned off via the HMSS. If the voltage level of the unit power supply is too low or too high, an alarm (A0) is gener-ated to the HMSS.

HDS-C structure

SAS controllerThe SAS controller is a four-port, 3.0 Gbit/s SAS/ SATA controller that is compliant with the Fusion-MPT (Message Passing Technology) architecture. It provides a four-lane PCI Express interface, and supports the Integrated RAID technology.

The SAS controller supports the PCI Express Base Specification (Revision 1.0a), and the ANSI Serial Attached SCSI Standard (Revision 1.1).

The SAS/ SATA link rates for each SAS PHYs on the SAS controller can reach to 3.0 Gb/s or 1.5 Gb/s. Each port supports the SSP, SMP, STP, and SATA protocols.

The SAS controller provides two 3.0 Gbit/s interfaces to the on-board HDD and the SAS controller on the redundant HDS-C unit, and one PCI-E interface to the OMU.

HDD hot swap controllerThe hot swappable controller controls the power supply of the HDD and makes it possible to change the HDD without turnning off the plug-in unit.

3.3 External interfaces of HDS-CFront panel interfacesThe following external interfaces of the HDS-C unit pass through the front panel:

Mini-SAS interfaceThere is one min-SAS connector on the front panel, which connects to the redundant HDD on the redundant HDS-C unit.

PCI-E x4 interfaceOne x4 PCI-E interface is provided through the shielded QSFP connector at the HDS-C front panel and it connects to the OMU. The x4 PCI-E interface operates at 10 GT/s and provides maximum data rate of 8 Gbit/s.

Backplane interfacesThe HDS-C connects to the backplane with two 2.0 Hard Metric connectors. The con-nector modules are numbered from 1 to 2 from the top to the bottom. The upper-most connector in module 1 is an unshielded type-A connector with 110 positions. This con-nector is for multipurpose. The connector in module 2 is upper shielded type-B connec-tor. The numbering of the connector rows is from 1 to 50 from the top to the bottom.
