Optimizing spool and memory space management

A tangible, non-transitory, computer-readable media having instructions thereupon which, when executed by a processor, cause the processor to perform a method comprising:

• allocating, by a memory manager in a storage system, virtual units of NVRAM (nonvolatile random-access memory) with mapping of the virtual units to physical memory;
• writing data having various sizes into allocated first virtual units of memory each comprising a first contiguous physical addressed amount of NVRAM having a first size, and into allocated second virtual units of memory each comprising an amount of NVRAM having a second size;
• and
• relocating at least some of the data such that a portion of the allocated second virtual units of memory become available for the allocating.

A storage system, comprising:

• NVRAM (nonvolatile random-access memory);
• solid-state storage memory;
• and
• a processor, to perform a method, comprising:
• allocating virtual units of NVRAM with mapping of the virtual units to physical memory;
• writing data having various sizes into allocated first virtual units of memory each comprising a first contiguous physical addressed amount of NVRAM having a first size, and into allocated second virtual units of memory each comprising an amount of NVRAM having a second size;
• and
• relocating at least some of the data such that a portion of the allocated second virtual units of memory become available for the allocating.
