Table 4 represents the minimum, middle, and maximum memory combinations possible for the 4, 8, 16, and 32 GB
memory kits available for the DL980 G7 servers. However, for best performance use dual or quad rank memory DIMMs.

Note:
Max memory depends on the number of processors configured. Four/eight
processor configurations support up to 2TB/4TB of memory, respectively.
However Linux 2.6.18 Kernel only supports up to 1TB. The Linux 2.6.32 Kernel
expands memory support to 2TB memory or higher based on the Linux
implementation. Windows Server 2008 supports up to 2TB currently.
Table 5. VMA supported Expansion Slot Configurations
Expansion Slots
Standard Main I/O with 5 Gen2 slots: (3) x4 PCI-Express; (2) x8 PCI-Express
PCIe Option with 6 slots: (1) x4 Gen1 PCI-Express; (1) x4 Gen2 PCI-Express (4) x8 Gen2 PCI-Express
Low Profile Expansion Option with 5 Gen2 slots; (1) x4 PCI-Express; (4) x8 PCI-Express
Note:
The PCI-X and PCIe Combination Option slots are not to be used for HP VMA-
series Memory Arrays. I/O slots capable of bi-directional x8 PCIe provide the best
performance.
The DL980 G7 server comes with the Standard Main I/O board with PCIe slots 7-11. Slots 9 and 11 are x8 Gen2 PCIe slots.
The PCIe expander option provides additional I/O slots 1-6. Slots 2, 3, 5 and 6 are x8 Gen2 PCIe slots. The low profile
expansion option provides additional I/O slots 12-16. Slots 12, 13, 15, and 16 are x8 Gen2 PCIe slots. For configuration
three, the DL980 with eight VMA arrays requires eight PCIe slots. In order to get the best performance for configurations
two and three you will need to also install the low profile expansion option to optimize performance with the PCIe x8
slots. If a VMA Array is ordered with a DL980 G7, PCIe Option I/O Expansion (588137-B21) is integrated regardless. If 3 or
more (up to 8) VMA Arrays are ordered with the DL980 G7, the low profile PCIe Option (AM434A) is automatically
