Context Before

Situated at the back of the chassis, the Strata module of VR NVL72 is the equivalent of the Bianca board of GB200/300. It houses two Rubin GPUs and one Vera CPU. Unlike Bianca, the LPDDR5X memory for Vera is socketed via SOCAMM module. 8 SOCAMM sockets are placed on the left and right of Vera. Two SOCAMM modules of different capacities are offered, 192GByte and 128GByte, for a maximum of 1,534GByte and a minimum of 1,024GByte per Vera.

Evidence

The Connect-X NICs mezzanine module is also taken off the Strata module as CX-9 is moved to the front of the chassis.

Context After

Under the cableless design, all the cable connector ports are also removed and replaced by Paladin HD2 board-to-board connectors at the bottom of the module. On the other side, the same set of Paladin HD2 backplane connectors as GB200 and GB300 are identically placed at the back of the module connecting to the NVLink 6 Switches via the NVLink backplane.

② Atomic Claim

Connect-X NIC mezzanine module 也從 Strata module 移除，因為 CX-9 被移到 chassis 前方。
