摘要： A replicated decentralized storage system comprises a plurality of servers that locally store disk images for locally running virtual machines as well as disk images, for failover purposes, for remotely running virtual machines. To ensure that disk images stored for failover purposes are properly replicated upon an update of the disk image on the server running the virtual machine, a hash of a unique value known only to the server running the virtual machine is used to verify the origin of update operations that have been transmitted by the server to the other servers storing replications of the disk image for failover purposes. If verified, the update operations are added to such failover disk images.

摘要： Methods and system for adding a data record to a file comprise maintaining a data structure to track locations of data records within the file, wherein each entry in the data structure is a Bloom filter that corresponds to a different portion of the file that includes a plurality of data records. When an instruction to write data to the file is received, a data record is generated to append to the file, wherein the data record comprises a randomized unique id and the data from the received instruction. A Bloom filter bit pattern is extracted from the randomized unique id and bits in a current Bloom filter entry of the data structure are set, wherein the set bits correspond to the same bit positions as the Bloom filter bit pattern. The data record is thus able to be added to the file.
摘要翻译：用于将数据记录添加到文件的方法和系统包括维护数据结构以跟踪文件内的数据记录的位置，其中数据结构中的每个条目是对应于包括多个文件的文件的不同部分的布隆过滤器的数据记录。当接收到向文件写入数据的指令时，生成数据记录以附加到文件，其中数据记录包括随机化唯一ID和来自接收到的指令的数据。从随机化唯一ID提取布隆过滤器比特模式，并且设置数据结构的当前布隆过滤器条目中的比特，其中所设置的比特对应于与布隆过滤器比特模式相同的比特位置。因此，数据记录能够被添加到文件中。

摘要： Methods and systems for utilizing local storage of host computers to emulate a centralized storage system comprise receiving a write operation from a virtual machine running on a first host computer, wherein the write operation corresponds to a disk image that is locally stored in a first host computer. The disk image and a second disk image is updated in accordance with the write operation, wherein (i) the second disk image is locally stored on a second host computer that is networked to the first host computer, (ii) the second disk image serves as a back-up to the disk image, and (ii) the second host computer is configured to support the running of other virtual machines that access other disks images that (a) are locally stored on the second host computer, and (b) are further backed-up on at least a third host computer.

摘要： A cluster of computer systems, each of which is configured with a virtualization software layer to support execution of virtual computing instances, includes a first computer system in which a first virtual computing instance is executing, the first computer system including a first local storage unit in which a first log file is stored to capture write operations to a virtual disk of the first virtual computing instance. The cluster also includes a second computer system, networked to the first computer system, in which a second virtual computing instance is executing, the second computer system including a second local storage unit in which a second log file is stored to capture write operations to a virtual disk of the second virtual computing instance and in which a replica of the first log file is stored.
