Abstract
When a virtual machine sends a write command to a host operating system, a cache system stores the record included in the write command and later sends the write command to a storage system. Systems and methods store an indication of when the write command was received along with the received records in the cache. The cache system determines an order of the records from the indication. In some instances, records received at the same time are serialized and/or assigned record numbers. The simultaneously received records can be assigned a batch number. According to the determined order, the records are retrieved from the cache memory and included in write commands sent to the storage system. In some instances, checkpoints can be stored to prevent records from being re-sent to the storage system following a failure.
