ServeRAID M1215 SAS/SATA Controller
Product Guide (withdrawn product)
The ServeRAID M1215 SAS/SATA Controller is a low-cost 12 Gbps internal RAID 0/1/10 solution that can
be upgraded to a cacheless RAID 5 with a Features on Demand (FoD) license upgrade. The M1215
provides two internal mini-SAS HD connectors with eight lanes of 12 Gbps SAS and eight lanes of PCIe 3.0
to facilitate high data transfer rates.
The M1215 controller is a part of the ServeRAID M Series family that offers a complete server storage
solution consisting of RAID controllers, cache/flash modules, energy packs, and software feature upgrades
in an ultra-flexible offerings structure.

Did you know?
The M1215 is an entry-level internal data storage solution that provides hardware RAID capabilities and
advanced features, such as online capacity expansion and RAID-level migration. The optional RAID 5
upgrade and support for self encrypting drives no longer requires a hardware key because the upgrade
functionality is implemented through Features on Demand (FoD) software licenses.
With increased demand for performance and advanced features, the M1215 provides a seamless migration
path to the full-featured RAID controllers, such as the ServeRAID M5210. The information about existing
arrays can be recognized and imported into the new controller without any reconfiguration.
Rigorous testing of the M1215 by Lenovo through the ServerProven® program ensures a high degree of
confidence in storage subsystem compatibility and reliability. Providing an additional peace of mind, this
controller is covered under Lenovo warranty.

Features
The ServeRAID M1215 SAS/SATA Controller has the following standard features:
Auto-resume on array rebuild or array reconstruction after loss of system power
Auto-resume uses non-volatile RAM (NVRAM) to save rebuild progress during a host reboot or
power failure to automatically resume from the last checkpoint. Auto-resume ensures that data
integrity is maintained through the process. The card supports a number of features that are able to
be implemented without rebooting the server. Applications, such as email and web server, benefit
from avoiding downtime during transition.
Online Capacity Expansion
Online Capacity Expansion (OCE) allows the capacity of a virtual disk to be expanded by adding
new physical disks or making use of unused space on existing disks, without requiring a reboot.
Online RAID Level Migration
Online RAID Level Migration (also known as logical drive migration) provides the ability to migrate a
virtual disk from any RAID level to any other RAID level without requiring a reboot. System
availability and application functionality remain unaffected.
Fast initialization for quick array setup
Fast initialization quickly writes zeroes to the first and last sectors of the virtual drive. This feature
allows you to immediately start writing data to the virtual drive while the initialization is running in the
background.
Consistency check for background data integrity
Consistency check verifies that all stripes in a virtual disk with a redundant RAID level are
consistent. The consistency check will mirror data when an inconsistent stripe is detected for a RAID
1 and will recreate the parity from the peer disks in the case of a RAID 5. Consistency checks can
be scheduled to take place periodically.
