Information About Hardware |
This chapter describes special instructions and issues about M3000 server hardware.
For servers that have the B-type plug, confirm that a 15A overcurrent protection device is available outside the server. If one is not available, prepare an external 15A overcurrent protection that can be achieved by means of no-fuse breakers (NFBs) or fuses. The B-type plug refers to plugs other than grounding-type ones with two parallel blades, such as the NEMA L6-30, L6-20, L6-15, and L5-15.
It is not supported to connect an SAS device containing multiple SAS targets to the onboard external SAS interface. Instead, use a Sun StorageTek Host Bus Adaptor (SG-XPCIE8SAS-E-Z). [CR 6765239]
Sun Storage J4200 SAS JBOD arrays have six general-purpose SAS connectors. With FW version 3A32 or higher, each of them can be connected to separate SAS initiators, therefore up to six systems can be connected to the array. Each system can use a different disk on the array as its boot device. J4200 arrays have 12 disks, so each boot device can be mirrored for higher reliability. J4200 SAS arrays can be configured into multiple zones to provide a more secure environment.

See especially:
To execute the dumpconfig(8), restoreconfig(8) or snapshot(8) command, if you specify USB memory as the destination to store data, prepare the USB memory as a medium in advance.
The data stored will include the information about the system. To use USB memory, you need to pay attention to the management of the USB memory in which the data stored, from the data security viewpoint.
We do not provide guarantees on the proper operation and connectivity to the XSCF of every USB memory currently manufactured on the market. Depending on the USB memory in use, defects such as the XSCF firmware error or reset may occur. In case such defects occurred, stop the use of USB memory immediately.
To connect the USB memory to the USB port for the XSCF, connect the USB memory directly to the USB port. If connected via the USB hub or USB extension, it might cause errors.
