Hardware components

This articles describes the ECS Appliance hardware components.

The appliance comes in two configurations:

U-Series Appliances include the following:

Nodes

ECS Appliance has two node types:

U-Series nodes have the following standard features:

C-Series nodes have the following standard features:

Server rear view

The server chassis provides dual hot-swappable power supplies and four compute nodes. The chassis shares a common redundant power supply (CRPS) that enables HA power in each chassis shared across all nodes. The nodes are mounted on hot-swappable trays that fit into the four corresponding node slots accessible from the rear of the server.

  • 1. Node 1
  • 2. Node 2
  • 3. Node 3
  • 4. Node 4

U-Series server chassis rear view

  • 1. 1GbE: Connected to one of the 1 GbE switches data port.
  • 2. RMM: A dedicated port for hardware monitoring (per node)
  • 3. SAS to DAE (U-Series only)
  • 4. 10 GbE (secondary): The right 10 GbE data port of each node is connected to one of the 10GbE switch's primary data ports
  • 5. 10 GbE (primary): The left 10 GbE data port of each node is connected to one of the 10GbE switch's secondary data ports

Node host names

Nodes are assigned host names based on their order within the chassis and within the rack itself. The following table lists the host names.

Disks and enclosures

U-Series disk enclosures have the following features:

The DAE is a drawer that slides in and out of the 40U dense rack. The disk drives, LCC, and cooling modules for the DAE are located inside the DAE.

C-Series servers have integrated disk enclosures with the following features:

Disk drives

Disk drives are encased in cartridge-style enclosures. Each cartridge has a latch that allows you to snap-out a disk drive for removal and snap-in for installation. The DAE supports:

The inside of each DAE has physically printed labels located on the left and the front sides of the DAE that describe the rows (or banks) and the columns (or slots) of where the disks are installed in the DAE. Looking at the DAE from the front and above, the following figure shows you the disk drive layout of the DAE.

Note Image
15 and 45 disk configurations also available.

U-Series disk layout for 60 and 30 disk configurations

The banks are labeled from A to E and the slots are labeled from 0 to 11. When describing the layout of disks within the DAE, the interface format for the DAE is called E_D. That is, E indicates the enclosure, and D the disk. For example, you could have an interface format of 1_B11. This format is interpreted as enclosure 1, in row (bank) B/slot number 11.

Enclosures are numbered from 1 through 8 starting at the bottom of the rack. Rear cable connections are color-coded.

LCC

Each DAE includes a hot-swappable LCC whose main function is to be a SAS expander and provide enclosure services. The LCC independently monitors the environment status of the entire enclosure and communicates the status to the system. The LCC includes a fault LED and a power LED.

Fan control module

Each DAE includes three fan control modules (cooling modules) located on the front of the DAE. The fan control module augments the cooling capacity of each DAE. It plugs directly into the DAE baseboard from the top of the DAE. Inside the fan control module, sensors measure the external ambient temperatures to ensure even cooling throughout the DAE.

ICM

The ICM is the primary interconnect management element. It is a plug-in module that includes a USB connector, RJ-12 management adapter, Bus ID indicator, enclosure ID indicator, two input SAS connectors and two output SAS connectors with corresponding LEDs indicating the link and activity of each SAS connector for input and output to devices.

The ICM supports the following I/O ports on the rear:

  • Four 6-Gb/s PCI Gen 2 SAS ports
  • One management (RJ-12) connector to the SPS (field service diagnostics only)
  • One USB connector
  • 6-Gb/s SAS x8 ports

It supports four (two input and two output, one used) 6-Gb/s SAS x8 ports on the rear of the ICM. This port provides an interface for SAS and NL-SAS drives in the DAE.

DAE power supply

The power supply is hot-swappable. It has a built-in thumbscrew for ease of installation and removal. Each power supply includes a fan to provide cooling to the power supply. The power supply is an auto-ranging, power-factor-corrected, multi-output, offline converter with its own line cord. Each supply supports a fully configured DAE and shares load currents with the other supply. The DAE, the power supplies provide four independent power zones. Each of the hot-swappable power supplies has the capability to deliver 1300 W at 12 V in its load-sharing highly-available configuration. Control and status are implemented throughout the I2C interface.
