To achieve an optimal balance of performance, capacity, cost, and density, Teradata chose the following physical node configuration for the ESXi nodes running Analytics Database:
- Dell R660 1U PowerEdge Server (10 x 2.5” Drive Bay Chassis and three PCIe4x16 I/O slots):
- Two Intel Xeon Gold 5418Y CPUs (24 Physical Cores each, 2.0GHz, with H/T Enabled)
- 768GB RAM Memory (twelve 64GB DDR5 4800MT/s DIMMs) running @ 4400MT/s
- I/O Riser Config 1, 2+3 (3 PCIe4x16 Low-Profile I/O slots)
- Three 2-port ConnectX-6 25GbE Ethernet NICs
- One OCP 3.0 four x 25GbE NIC (CLAN, DSU, CMIC, vSphere, or ESXi)
- PERC H755 RAID Controller Card (internal, for OS)
- Two 1.6TB SAS SED FIPS-140 Mixed Use 3DWPD SSDs (for OS)
- I/O Expansion Slots within R660:
- Riser 2 (Slot 1, connected to CPU 1): Two x 25GbE (iSCSI and BYNET)
- Riser 2 (Slot 2, connected to CPU 2): Two x 25GbE (iSCSI and BYNET)
- Riser 3 (Slot 3, connected to CPU 2): Two x 25GbE (iSCSI)
- Daughter card: Two x 25GbE (CLAN, DSU, CMIC, vSphere or ESXi)
The allocation of expansion slots as stated in the previous section provides the following attributes:
- Up to 8GB/s of aggregate network bandwidth (dedicated to storage)
- Redundant NICs for Storage I/O
- Balanced allocation of high-traffic NICs across both CPUs
- Up to 4GB/s of aggregate network bandwidth for BYNET Interconnect
- Up to 4GB/s of aggregate network bandwidth for platform management (ESXi, vSphere, CMIC VMs, ServiceConnect) and applications requiring data ingress/egress from the database (DSU, Data Mover, Viewpoint, CLAN)
Two Self-Encrypting (SED) solid-state drives (SSDs) within the R660 node are installed for ESXi and VantageCore VMware OS (SLES) purposes, as shown in the following image. These drives are defined with a 1+1 RAID-1 vdisk, managed by the Dell PERC H755 within the node.
Important: Analytics Database ESXi hosts are allocated to the Teradata system application. Allocation of non-Vantage systems on the ESXi hosts is not supported.
