Key points to note on these 00JY196 Lenovo M1210 SA / SATA controllers:-

The M1210 controller is a PCI Express 3.0, low-profile, low-height RAID controller based on the LSISAS3004 PCI Express-SAS/SATA input/output (I/O) processor chip. The M1210 controller brings 12 Gbps Serial Attached SCSI (SAS) and 6 Gbps Serial ATA (SATA) performance to host controller, workstation, and server designs.

The M1210 controller supports internal storage devices, which enables you to use a system that supports enterprise-class SAS drives, and desktop-class SATA drives. The M1210 controller can connect to drives directly. Simplified cabling between devices is an additional benefit. The M1210 controller supports four internal SAS/SATA ports through one internal x4 Mini-SAS HD connector (SFF-8643).

The M1210 controller integrates four high-performance SAS/SATA physical layers (PHYs) and a PCI Express bus master direct memory access (DMA) core. Each of the four PHYs supports 12 Gbps SAS link rates and 6 Gbps SATA III link rates. The LSISAS3004 device increases system performance and provides fault-tolerant data storage.

The LSISAS3004 input/output controller (IOC) device supports data striping across multiple disks, which reduces disk access time because multiple disks read or write data simultaneously. In addition, the device backs up data with either data mirroring or a parity block. Either backup method enables you to recover lost data in the event of a disk failure.

You can select the data backup method that best suits your needs. The M1210 controller supports the SAS protocol as described in the Serial Attached SCSI Standard, version 3.0, and the SATA III protocol defined by the Serial ATA Revision 3.0 Specification. Note: You cannot mix SAS drives and SATA drives in the same virtual drive.

Each port on the M1210 controller supports SAS devices, SATA devices, or both using the following:

• • SAS Serial SCSI Protocol (SSP), which enables communication with other SAS devices
• • SATA, which enables communication with other SATA devices
• • Serial Management Protocol (SMP), which communicates topology management information directly with an attached SAS expander device
• • Serial Tunneling Protocol (STP), which enables communication with a SATA device through an attached expander.
•  

The M1210 controller supports 64-bit logical block addressing (LBA), which makes it possible to connect many drives to the RAID controller, directly and through expanders. However, the actual number of drives that you can attach depends on the requirements rather than by the actual RAID volume capacity.

The maximum drive numbers depend on how many physical devices you have connected to the M1210 controller. For example, the maximum number of arrays per controller is equal to the number of physical disks supported by the M1210 controller, up to the limit of 32 arrays per controller.

In addition, though you can have up to 16 virtual disks per array, and up to 32 arrays per controller, the M1210 controller supports a maximum of 32 virtual disks.
