Managing drive space among different data services environments within a storage system

Data storage equipment, comprising:

• memory;
• and
• control circuitry coupled to the memory, the memory storing instructions which, when carried out by the control circuitry, cause the control circuitry to manage drive space within a storage system having a main data services environment configured to perform data storage operations on behalf of a set of hosts and a simple data services environment configured to load the main data services environment by performing a method of:
• while the simple data services environment is running on the storage system, using the simple data services environment to load the main data services environment on to the storage system,
• after the main data services environment is loaded on to the storage system, providing a drive space communication from the simple data services environment to the main data services environment, and
• receiving, by the simple data services environment, allocation of drive space from the main data services environment in response to the drive space communication.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to manage drive space within a storage system having a main data services environment configured to perform data storage operations on behalf of a set of hosts and a simple data services environment configured to load the main data services environment;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• while the simple data services environment is running on the storage system, using the simple data services environment to load the main data services environment on to the storage system;
• after the main data services environment is loaded on to the storage system, providing a drive space communication from the simple data services environment to the main data services environment;
• and
• receiving, by the simple data services environment, allocation of drive space from the main data services environment in response to the drive space communication.
