NO. Requirements in this Relationship with related specifications from other SDOs
Recommendation
– [b-OCP BS] provides multiple interfaces for storage as 'PCIe Expansion Slot;
SATA hot-plug drives' in clause 2, Table 2-1.
– [b-OCP DSBS] provides multiple interfaces for storage as 'Storage: Two
single port AHCI SATA connectors capable of supporting up to 6 Gb/sec; Two
SCU 4-port mini-SAS connectors capable of supporting up to 3 Gb/sec
SATA/SAS; Two 4-port mini HD connectors capable of supporting up to 6
Gb/sec SATA' and 'Support for PCI Express* 225W/300W High Power Card
Electromechanical Specification 1.0' in clause 4, Tables 1 and 2.
– [b-OCP G1] provides multiple interfaces for storage as '15x 12Gb/s SAS or
6Gb/s SATA 2.5' drive slots, up to 15mm thickness, connected via SEB, to an
onboard HBA. One M.2 SATA slot, also on board.' and '1 x 16 Gen3 FH/FL, 2 x8
Gen3 LP/HL, 1 x8 OCP Mez with front Panel access, 1 x8 PCIe OCP Mez in a
non-front-accessible internal slot to support SAS HBA or Raid-on-Chip with
SuperCap' in clause 6.1.
– [b-OCP HSAS] provides multiple interfaces for storage as '▪ Intel C612
Controller;▪ (2) discrete SATA 7pin for SATA4 and SATA5;▪ (2) MiniSAS SFF-
8087 for SATA0~SATA3, sSATA0~sSATA3;▪ 6.0Gb/s speed;▪ SATA SGPIO
supported;▪ RAID 0/1/10/5 (Intel RST);▪ (4) Internal MiniSASHD SFF-8643
connectors (Optional)' in clause 8.
– [b- OCP HSCH] provides multiple interfaces for storage as 'The SATA
connections are a minimum of SATA2.0 (3Gb/s) and may be SATA3.0
(6Gb/s).The PCIe connection is a minimum of PCIe 2.0 and may be PCIe 3.0'
in clauses 6.4 and 6.5.
– [b-OCP OAPM] provides multiple interfaces for storage as 'SATA, and PCI-
Express Expansion' in clause 5.
– [b-OCP MB] provides multiple interfaces for storage as 'The motherboard
uses Intel C610 series chipset, which supports following features: 3x USB
3.0/2.0 ports: one for front connector; one for optional vertical on board
connector; one for BMC in-band firmware update; 1x mSATA connector
from SATA port 4 co-layout with M.2 connector; 1x individual SATA 6Gps
ports from SATA port 5; 1x miniSAS port from SATA port 0/1/2/3, 1x
miniSAS port from sSATA0/1/2/3; 1x PCIe x4 ports to M.2 connector; SPI
interface, connect to BMC to enable BMC the capability to perform BIOS
upgrade and recovery; SMBUS interface (master and slave); Intel Server
Platform Services (SPS) 3.0 Firmware with Intel Node Manager' in clause 5.4.
10 Storage replacement – [b-OCP 1S] provides storage replacement as 'The carrier assembly includes
2x ejectors which are used for card injection/ejection into the PCIe
connectors' in clause 5.1.
– [b-OCP 1S] provides storage replacement as 'The Twin Lakes 1S server
supports three M.2 solid-state drives in 2280 or 22110 form factors. Boot
M.2 slot is only available in 2280 form factor and it can be configured as
either SATA or PCIe interface through BOM options, but not both. A
minimum 256GB M.2 SATA or NVMe SSD is required as a boot device and
for logging purpose. Two additional SSD drives are designed in to support
applications that require high disk performance. These two M.2 slots only
support PCIe X4 links but both support SSD drives in 2280 or 22110 form
factors' in clause 9.4.
– [b-OCP 2S] provides storage replacement as 'The motherboard uses Intel
PCH chipset, which supports following features: 4x USB 3.0/2.0 ports: one
type A for front connector; one type C for front connector; one for BMC in-
band firmware update; one to X32 riser connector; 1x M.2 connector; 1x
individual SATA 6Gps port; 1x miniSAS HD x8 port or 1x miniSAS HD x4 port;
