Abstract:
Approaches for minimizing the amount of write transactions issued to an object store maintained on a solid state device (SSD). Transactions requested against an object store maintained on a SSD may be committed once transaction information for the transaction is durably stored in a non-volatile dynamic random access memory (DRAM), which may be maintained in a HDD controller. Further, data blocks stored in a volatile cache of a database server that issues write requests to an object store maintained on one or more SSDs may be considered persistent stored once confirmation is received that the data blocks are written to a double-write buffer stored on a non-volatile medium, such as NV RAM in a HDD controller. Additionally, any data blocks that are to be written over in a non-volatile DRAM are first ensured to be no longer present within the volatile write cache maintained a the solid state device.
