2.10 Out of Band Management (SMBUS)
Intel
®
SSD DC P3700 Series provides out of band management by means of SMBUS interface. This
requires 3.3V Auxiliary voltage. SMBUS accesses a VPD page as listed in Appendix B through address
0X53.
Temperature sensor is accessed through address 0x1B. For temperature sensor access, temperature
can be read by the BMC (base) using Read Temperature Data Register (0x05) by means of SMBUS
0x1B. Bits [11:0] return raw ambient temperature.
Host may also see 0x66 address in a bus scan. This is only used for write protecting the EEPROM
during manufacturing.
Note: In certain tools the address for the VPD and temperature sensor will appear as 0xA6 and 0x36
respectively, due to bit shift.
2.11 Variable Sector Size Support
P3700 Series supports 512, 520, 528, 4096, 4104, 4160 and 4224 bytes of sector size. P3700 Series
will also support DIF as specified in NVMe* 1.0 specification. Host sector sizes supporting DIF are 512
bytes and 4096 bytes with a PI (Protection Information)
of 8 bytes.
In terms of protection information action (PRACT), bit 29 of DWORD12 in READ/WRITE command
should not be equal to 1. Device only supports PRACT=0 implying protection information is passed
to the SSD and checked by the SSD.
