The following table outlines the features and components of the appliance.
Feature | Feature Description |
---|---|
SAS HPA Worker Node
|
SAS worker nodes are available as SAS HPA Base nodes and SAS HPA Performance nodes. SAS HPA Base Worker nodes consist of a Dell R730 chassis with:
SAS HPA Performance Worker nodes consist of a Dell R730xd chassis with:
Each SAS HPA worker node provides:
Each SAS HPA worker node may have the
following Ethernet adapters:
|
SAS Mid-Tier nodes (optional) | The SAS HPA Mid-Tier node runs
additional SAS software that hosts SAS web services supporting the
SAS Visual Analytics (VA) applications. SAS HPA Mid-Tier nodes consist of a Dell R730 chassis with:
Each SAS HPA Mid-Tier node provides:
Each SAS HPA Mid-Tier node may have the
following Ethernet adapters:
|
SAS App Server | The SAS App Server is a Dell
R730xd server used for solution offerings that are peripheral to
Teradata processing. SAS App Server nodes consist
of a Dell R730xd chassis with:
The SAS App Server provides onboard connectivity to the server management network. It can also be connected to InfiniBand switches. If the option to connect to an InfiniBand switch is used, port consumption ramifications should be considered. Each SAS App Server may
have the following Ethernet adapters:
|
Teradata Connect Node | Teradata Connect nodes are used in
systems that connect to BYNET V4 and BYNET-Over-Ethernet systems.
The Teradata Connect node connects the SAS HPA Appliance to the
Teradata data source. Teradata Connect nodes
consist of an Intel R1208 or R1208WT chassis with:
|
Adapters |
SAS HPA Base,
Performance, and Mid-Tier nodes and SAS App Server:
Teradata Connect node:
|
Cable Modes | Teradata systems are shipped with multi-mode fiber (MMF) connections for the 10Gb Ethernet optical interface into all servers. Single-mode fiber (SMF) connections are not supported. |
InfiniBand Interconnect | All SAS 750 Appliance
configurations use redundant 36-port InfiniBand switches to enable
node to node communication. For BYNET V4 and BYNET-Over-Ethernet
configurations that use Teradata Connect nodes, the InfiniBand
switches also connect to the Teradata Connect nodes. For two-cabinet systems (up to 33 nodes for UDA/InfiniBand systems, up to 36 nodes for BYNET V4 and BYNET-Over-Ethernet configurations) the 36-port InfiniBand switches are located in the base cabinet. For three-cabinet systems (up to 54 nodes for UDA/InfiniBand systems, up to 60 nodes for BYNET V4 and BYNET-Over-Ethernet configurations) pairs of 36-port InfiniBand switches are located in the base cabinet and one of the expansion cabinets, and an additional pair of second-tier switches is located in the other expansion cabinet. For larger systems (up to 126 nodes for UDA/InfiniBand systems, up to 180 nodes for BYNET V4 and BYNET-Over-Ethernet configurations) pairs of 36-port InfiniBand switches are located in base and expansion cabinets, and additional pairs of second-tier switches are located in the other expansion cabinets. UDA/InfiniBand systems can expand to 7 cabinets, and BYNET V4 and BYNET-Over-Ethernet systems can expand to 9 cabinets. For UDA systems with more than 126 nodes, and for non-UDA InfiniBand systems with more than 180 nodes, the switches in the SAS Appliance cabinet connect to larger second-tier switches located in the BYNET cabinet. |
Virtualized Management Server (VMS) | A virtualized management server
(VMS) resides in each appliance cabinet. A VMS is
an Intel R1208 or R1208WT chassis and can host the following
virtual machines (VMs):
An Intel R1208 or R1208WT VMS is available in System VMS and Cabinet VMS configurations. Each System VMS consists of:
Each Cabinet VMS consists of:
|
Server Management Web (SMWeb) Services | Server management functions run on the CMIC VM (on a VMS). The CMIC hosts the SMWeb Services Home page and provides applications and services for server management on an MPP system:
For use by customer on-site staff members, Teradata Services Analysts in the Global Support Center (GSC), and Teradata Customer Service Representatives. SMWeb 10.04 and Teradata ServiceConnect are required for the appliance.
For information about using SMWeb Services, see the Teradata Server Management Web Services User Guide, B035-5350, or the online help on the SMWeb Services home page. |
KVM Console | The KVM console can reside in an appliance base or expansion cabinet, or in the optional InfiniBand switch cabinet. The KVM should be located in the same cabinet as and be connected to the System VMS or rack-mounted SWS workstation. |
Cable Management | Appliance cabinets have cable
harnesses for server management. InfiniBand cabinets do not have cable harnesses. Openings in cabinet sides near the rear of the rack accommodate inter-rack cabling. |
AC Power Subsystem | Appliance cabinets:
