Abstract

In some embodiments, a storage controller comprises a first input/output port that provides an interface to a host computer, a second input/output port that provides an interface a storage device, a processor that receives input/output requests generated by the host computer and, in response to the input/output requests, generates and transmits input/output requests to the storage device, and a memory module communicatively connected to the processor. The memory module comprises logic instructions stored in a computer-readable medium which, when executed by the processor, configure the processor to receive, from the host computer, a write input/output request that identifies a logical volume; compare an amount of storage space available in the logical volume with an amount of storage space required to complete the write operation, and allocate additional storage space to the logical volume if the amount of storage space available in the logical volume is insufficient to complete the write operation. Other embodiments may be described.
