Intel® Solid-State Drive DC P3700 Series
May 2015 Product Specification
330566-009US 17
2.9 Hot Plug Support
2.5-inch form factor will support surprise hot plug feature in capable platforms and OSs. P3700 Series supports
hot insertion and removal and surprise hot insertion by means of presence detect and link-up detect. On surprise
hot removal during IOs, P3700 Series will ensure the integrity of already committed data on the media and commit
acknowledged writes to the media.
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 0X53/0XA6 (7bit/8bit).
Temperature sensor is accessed through address 0x1B/0x36(7bit/8bit). 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.
Intel SSD DC P3700 provides additional drive information via address 0x6/0xD4(7bit/8bit) as outlined in the NVMe
Basic Management Command (see http://www.nvmexpress.org/wp-content/uploads/NVMe_Management_-
_Technical_Note_on_Basic_Management_Command.pdf).
Appendix B, C and D have details on the Out of Band Management data structure.
NOTES:
1. In certain tools the address for the VPD and temperature sensor will appear as 0xA6 and 0x36
respectively, due to bit shift.
2. BMC should not access the SMBUS address within 100msec of device power up, it may experience
some glitch on the bus.
2.11 Variable Sector Size Support
P3700 Series supports 512, 520, 528, 4096, 4104, 4160 and 4224 byte sector sizes. 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.
