2145-SV1 PCI express expansion slot rules

Table 3 lists the optional adapters that are supported in each PCI express expansion slot.

Table 2. PCI express expansion slot rules for 2145-SV1 nodes
PCIe slot	Options that are supported in the specified slot
1	None
2	12 Gbps SAS adapter
3	4-port 16 Gbps Fibre Channel 10 Gbps Ethernet
4	4-port 16 Gbps Fibre Channel 10 Gbps Ethernet
5	12 Gbps SAS adapter Compression accelerator
6	4-port 16 Gbps Fibre Channel 10 Gbps Ethernet
7	4-port 16 Gbps Fibre Channel 10 Gbps Ethernet
8	Compression accelerator

2145-DH8 PCI express expansion slot rules

Use the rules in Table 3 to see which adapters are supported in each PCI express expansion slot.

Table 3. PCI express expansion slot rules for 2145-DH8 nodes
PCIe slot	Options that are supported in the specified 2145-DH8 slot
1	8 Gbps Fibre Channel 2-port 16 Gbps Fibre Channel 4-port 16 Gbps Fibre Channel
2	8 Gbps Fibre Channel 2-port 16 Gbps Fibre Channel 4-port 16 Gbps Fibre Channel 10 Gbps Ethernet (see note 1)
3	8 Gbps Fibre Channel (see note 2) 2-port 16 Gbps Fibre Channel 4-port 16 Gbps Fibre Channel 12 Gbps SAS
4	Compression accelerator (see note 3)
5	8 Gbps Fibre Channel 2-port 16 Gbps Fibre Channel 4-port 16 Gbps Fibre Channel 10 Gbps Ethernet (see note 1)
6	Compression accelerator (see note 3)
Notes: Each node supports only one 10 Gbps Ethernet adapter (see Table 1). An 8 Gbps Fibre Channel adapter in slot 3 needs a minimum software level of 7.6.0.3. If the system has only one compression accelerator, it can be installed in either slot 4 or 6.
