Internal Storage - Lenovo ThinkSystem SN550 Product Manual

Internal storage

The SN550 server has two 2.5-inch hot-swap drive bays that are accessible from the front of the blade
server (see Figure 2). Depending on server configuration and installed backplane, these bays connect to
either the included 6 Gbps SATA controller, optional Lenovo RAID controllers or directly to PCIe lanes for
NVMe drives. In addition, the SN550 can also support one or two M.2 form factor SSD drives on a
separate adapter. Storage backplanes, RAID and M.2 upgrades are listed below.
Virtualization support: The integrated SATA controller can be used with virtualization hypervisors,
including VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. However, support is limited to AHCI
(non-RAID) mode. RSTe mode is not supported with virtualization hypervisors.

M.2 drives
The server supports an adapter that provides two M.2 form-factor SATA drives for use as an operating
system boot solution. The drives are configured by default as a RAID-1 mirrored pair for redundancy.
The M.2 drives install into an M.2 adapter which in turn is installed in a dedicated slot on the system
board. See the internal view of the server in the
the M.2 slot.
The M.2 adapter supported is the Dual M.2 Boot Adapter, which supports one or two M.2 drives; available
as ThinkSystem M.2 with Mirroring Enablement Kit, 7Y37A01093 (note that the SIngle M.2 adapter is not
supported, but a single M.2 drive in the Dual M.2 Adapter is supported).
The Dual M.2 Boot Adapter with one 128GB M.2 drive partially inserted is shown in the following figure.
The second M.2 drive is installed on the other side of the adapter.
