摘要： Enhancing management of controllers in a RAID system when a post-write-cache of a is disabled, by supplying a stripe buffer that stores sequential write requests—and before such requests are actually written in to the physical disc drives. The stripe buffer can temporarily store data, until the data level reaches the stripe buffer size. Thereafter, contents of the stripe buffer can be flushed onto disc.

摘要： Virtual media device network communication is improved with a media filter that reduces unnecessary non-media access commands, such as test unit ready commands, that have an enhanced impact on data transfer rates when media devices communicate over a network. The media filter withholds communication of selected non-media information by a remote access controller associated with a virtual media device and generates simulated responses to the withheld communication for return to the virtual media device. In one embodiment, predetermined non-media access commands are withheld from communication to a network unless a timeout timer is expired. The timeout timer is set for a time period that precludes a media change between timeout timer expirations and is reset with successful response to a command through the network.

摘要翻译： 利用媒体过滤器改进虚拟媒体设备网络通信，该媒体过滤器减少了媒体设备通过网络进行通信时对数据传输速率的影响增强的不必要的非媒体访问命令（例如测试单元就绪命令）。 媒体过滤器通过与虚拟媒体设备相关联的远程访问控制器保留所选非媒体信息的通信，并且生成对被保留的通信的模拟响应以返回到虚拟媒体设备。 在一个实施例中，预定的非媒体访问命令被禁止从通信到网络，除非超时定时器期满。 超时定时器设置一段时间，可以阻止超时定时器到期之间的介质更改，并通过网络对命令成功响应进行复位。

摘要： User authorization and access information may be stored in a remote assistant card or chassis management module (CMM). The CMM may be in communication with each baseboard management controller (BMC) in a blade server system. Each BMC may authenticate its authorized users from the CMM using a simple user authorization retrieval command, e.g., IPMI Get Auth Code command. When an administrator wants to add or delete a user, the CMM may be updated instead of having to update each blade BMC. Each user may have a privilege list for any or all of the blades in the blade server system. This privilege list may define which user(s) apply to which blades, input-output (I/O) modules, and/or blade server system chassis.

摘要： A method and apparatus for protecting against overwrite and misread errors caused by cartridge movement comprises a read/write head and a read-write protection switch in electrical communication with the read-write head. The read-write protection switch generates an electrical signal upon movement of the media cartridge that disables the read/write head. A method of misread and overwrite protection comprises: detecting movement of the cartridge shell; disabling read/write heads; identifying whether the media drive was in the process of reading from or writing to the media cartridge; if the media drive was writing to the storage medium when the cartridge shell is moved, generating a write fault interrupt; and if the media drive is reading from the storage medium when the cartridge shell is moved, generating a read fault interrupt. A removable media cartridge has a push member and an abutment surface.

摘要： An information handling system includes a processor, system memory, and a remote access resource that includes a virtual card reader enabled to establish a communication channel between the remote access resource and a remote card reader to communicate smart card reader access requests and response between them. The system may include an authentication module requiring two factor authentication including userid/password authentication and a physical card authentication. The communication channel enables remote physical card authentication. The resource further supports redirection of system console traffic enabling remote userid/password authentication. The virtual card reader is preferably operable to download a virtual card reader client to a remote management station to which the smart card reader is attached. The remote access resource may be operable to direct console traffic of the system to the remote management station to display a system login screen on the remote management station.

摘要： A method of shutting down an information handling system is disclosed. Power is provided to a storage enclosure that includes a first storage device, a first operating condition monitor, and a first operating condition indicator having at least a first status and a second status. The status of the first operating condition indicator is updated based on the first operating condition monitor. One or more storage volumes are configured utilizing at least a portion of the storage enclosure. A first host detects the status of the first operating condition indicator. In response to detecting the first status of the first operating condition indicator, the first host determines whether the storage enclosure includes at least a portion of a critical storage volume and sends a shut down command from the first host to the storage enclosure. If the storage enclosure includes at least a portion of a critical storage volume, the first host is shut down.

摘要： An information handling system has the capability of securing serial console redirection via serial-over-LAN (SOL) by using a baseboard management controller (BMC) and a baseboard serial controller. The BMC may be coupled to the baseboard serial controller over a DCD and/or GPIO bus. De-assertion of the data carriage detect (DCD) signal from the BMC to the baseboard serial controller may cause the OS console to logout the user session. If the BMC does not support a DCD signal then a general purpose input-output (GPIO) signal from the BMC may be used instead. Most operating system (OS) consoles will logout a user session when a de-asserted DCD (or GPIO) signal is detected.
