Abstract

Disclosed is a method of identifying an unsupported storage device in a server (100, 200), the method comprises the following steps: providing baseboard management controllers (BMC) (106, 208) for servers (100, 200), enabling the BMC to obtain important product data (VPD) from a storage device (102a, 102b, 102c, 202a, 202b, 202c) on a server, compare the VPD from the storage device with one or more approved VPDs, and issue an output in response to the comparison.

Description

technical field

[0001] The present invention relates to a server and a method of identifying unsupported storage devices (aka "drives") in a server. Background technique

[0002] Computer customers tend to find ways to save money on server options, especially new technology storage devices such as Non-Volatile Memory Express (NVMe) drives. Challenges have been encountered during NVMe drive certification, showing that full support of NVMe drives requires rigorous testing to provide a stable and robust storage solution. Unfortunately, customers who do not purchase approved or qualified NVMe storage options may experience these compatibility issues and may result in service calls and fees for customers and manufacturers and / or suppliers.

[0003] There are currently no arrangements in place to restrict customers from installing substandard or unsupported storage devices into servers. This situation can lead to poor customer experience due to possible data loss due to server i...

Embodiment Construction

[0010] The present invention allows runtime detection and response to unsupported storage devices on a server.

[0011] The first step in this process involves identifying whether the storage device on the server is supported. exist figure 1 In the illustrated configuration, the server 100 includes a plurality of Serial Attached SCSI (SAS) drives and / or Serial AT Attachment (SATA) drives 102a, 102b, 102c, which are connected via a Small Computer System Interface (SCSI) storage enclosure processor ( SEP) 105 is connected to drive backplane 104 . The baseboard management controller (BMC) 106 of the server 100 is also connected to the driver backplane 104 via an inter-integrated circuit (I2C) 108 . To access SAS drives and / or SATA drives 102a, 102b, 102c, BMC 106 communicates with a redundant array of independent disks (RAID) / host bus adapter via Peripheral Component Interconnect Express (PCIe) (112) via Management Component Transport Protocol (MCTP) (HBA) controller 110 is co...
