摘要： A method, system, and computer program product provide a shared virtual memory space via a cluster-aware virtual input/output (I/O) server (VIOS). The VIOS receives a paging file request from a first LPAR and thin-provisions a logical unit (LU) within the virtual memory space as a shared paging file of the same storage amount as the minimum required capacity. The VIOS also autonomously maintains a logical redundancy LU (redundant LU) as a real-time copy of the provisioned/allocated LU, where the redundant LU is a dynamic copy of the allocated LU that is autonomously updated responsive to any changes within the allocated LU. Responsive to a second VIOS attempting to read a LU currently utilized by a first VIOS, the read request is autonomously redirected to the logical redundancy LU. The redundant LU can be utilized to facilitate migration of a client LPAR to a different computing electronic complex (CEC).

摘要： A mechanism is provided to enhance the scalability of network caching capabilities. All network client applications running on a partition in a virtualized environment are configured to query information from a single virtual input/output server (VIOS) network caching daemon. Thus, the illustrative embodiments provide a 1:n model where a VIOS partition has a network caching daemon, and each of the n partitions uses the network caching daemon of the VIOS partition. The mechanism of the illustrative embodiments only requires the system administrator to control one copy of the local files on the VIOS server. The system administrator does not need to monitor all of these local files on each individual partition. The system administrator consolidates the entries used by the different individual partitions into one single file on the VIOS server side.
摘要翻译：提供了一种增强网络缓存能力的可扩展性的机制。虚拟化环境中的分区上运行的所有网络客户端应用程序都配置为从单个虚拟输入/输出服务器（VIOS）网络缓存守护程序查询信息。因此，说明性实施例提供1：n模型，其中VIOS分区具有网络缓存守护进程，并且n个分区中的每个分区使用VIOS分区的网络缓存守护进程。说明性实施例的机制仅需要系统管理员来控制VIOS服务器上的本地文件的一个副本。系统管理员不需要监视每个单独分区上的所有这些本地文件。系统管理员将不同单独分区使用的条目合并到VIOS服务器端的单个文件中。

摘要： Systems, methods and media for providing to a plurality of WPARs private access to physical storage connected to a server through a VIOS are disclosed. In one embodiment, a server is logically partitioned to form a working partition comprising a WPAR manager and individual WPARs. Each WPAR is assigned to a different virtual port. The virtual ports are created by using NPIV protocol between the WPAR and VIOS. Thereby, each WPAR has private access to the physical storage connected to the VIOS.

摘要： A first virtual I/O server (VIOS) provides a cluster aware (CA) operating system (OS) executing on a processor resource of the first VIOS to register the first VIOS within a VIOS cluster. The first VIOS comprises a first field/failure data capture (FFDC) module that executes within the first VIOS and performs the functions of: receiving from an event listener a signal indicating that an FFFDC event/condition has been detected by the first VIOS; and automatically transmitting FFDC data to the shared storage repository for storage of the FFDC data within the shared storage repository. The FFDC module further performs the functions of: transmitting to one or more second VIOSes within the VIOS cluster, one or more messages to inform the one or more second VIOSes of an occurrence of the FFDC event/condition that was detected by the first VIOS.

摘要： A first Virtual Input/Output Server (VIOS) of a VIOS cluster performs the functions of: generating, at a sending daemon of the first VIOS, a send message that is to be transmitted to a receiving daemon at a second VIOS; in response to completion of the generating of the send message, forwarding the send message to a sending virtual small computer systems interface (vscsi) kernel extension (VKE) via a system call interface; and in response to the sending VKE receiving the send message from the sending daemon, forwarding the send message to one or more second VIOSes within the VIOS cluster utilizing a kcluster interface. The sending VKE parses at least one of a message header and a sub-header of the send message; and responsive to detection of a broadcast setting for the send message, the VKE forwards the send message to all nodes within the cluster via a cluster broadcast.

摘要： A method, system, and computer usable program product for addressing a workload partition are provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.

摘要： A method, an apparatus, and computer instructions are provided for a secure network install. One aspect of the present invention provides a proxy server within the same subnet of the client for performing a lookup of the boot image file and downloading the boot image file from a boot file server in a secure manner. The client in turn downloads the file from the proxy TFTP server. Another aspect of the present invention modifies the client remote boot code to include a secure boot file download discovery (SBDD) mode. The client starts the SBDD mode by sending a request for a boot image file to a subnet broadcast address and port, which is listened by a proxy TFTP server. The proxy TFTP server receives the client request and downloads the boot image file. The client in turn downloads the boot image file from the proxy TFTP server.
