Oracle Exalogic Elastic Cloud, Руководство пользователя

Страница: 23 / 342

Note:
If more than eight racks of Exalogic or Exadata are required to be connected
on the same InfiniBand fabric, Oracle offers a choice of several high-capacity
datacenter switches, which allow the creation of Exalogic clouds consisting of
hundreds of racks and tens of thousands of processors.
1.2.1 PDUs in Exalogic
Each Exalogic rack contains two redundant PDUs that are available in both high and
low voltage options
. The available PDU options can be found in the data sheets
available at the following location:
http://www.oracle.com/technetwork/server-storage/engineered-
systems/exalogic/index.html
Note:
When you upgrade to a full rack, you must upgrade to a three-phase 24 kVA
PDU.
1.2.2 Spares Kit for Exalogic
The Exalogic machine includes a spares kit containing additional parts and accessories
(cables, for example) that Oracle Services personnel will use to replace non-working
and broken parts quickly. When Oracle Services personnel visit your site for repairing
and replacing hardware, you should make the spares kit available to them. Note that
any parts used by Oracle Service personnel from the spares kit will be replenished by
Oracle.
1.2.3 Pre-cabling for Exalogic X4-2 and newer Machines
The eighth-, quarter-, and half-rack X4-2 and newer machines are pre-cabled with a
complete set (equivalent in number to a full rack) of InfiniBand (92), Ethernet (42), and
power cables. All the cables are connected to the appropriate switches and routed to
the correct rack-unit location. The unconnected ends of the cables are tied off to lacer
bars. At a later time, if the machine is upgraded to a larger rack, the filler panels and
lacer bars are removed, the X4-2 and newer servers are installed with rack rails and
cable-management arms, and the cables (power, InfiniBand, and Ethernet) are
connected to the newly installed compute nodes.
1.3 Exalogic Machine Rack Layout
The Exalogic machines are available in the following hardware configurations:
• full rack
• half rack
• quarter rack
• eighth rack
The following table displays the location of the hardware components on the 42 rack
units of an Exalogic machine. The table includes the information for all the available
