Assigning a data item to a storage location in a computing environment

Abstract

A computer implemented method, system, and/or computer program product assigns a data item to a storage location in a computing environment. A request to store a data item is detected. A determination is made as to whether a volatile memory in the second computer comports with an isolation rule for the data item. In response to determining that the volatile memory in the second computer comports with the isolation rule for the data item, access time for data in the volatile memory in the second computer is compared with access time for data in a local hard drive in a first computer. The data item is then selectively stored in either the volatile memory in the second computer or the local hard drive in the first computer as determined by their relative access times.

         11 . The computer program product of  claim 7 , further comprising:
 sixth program instructions to establish a threshold resource consumption rate for both the volatile memory in the second computer and the local hard drive in the first computer, wherein the threshold resource consumption rate sets a maximum permissible level of ancillary resources used to access the volatile memory in the second computer or the local hard drive in the first computer; and   seventh program instructions to select the volatile memory in the second computer or the local hard drive in the first computer to store the data item according to whether the volatile memory in the second computer or the local hard drive in the first computer has a lower threshold resource consumption rate relative to one another; and wherein   
       the sixth and seventh program instructions are stored on the computer readable storage media. 
     
     
         12 . The computer program product of  claim 11 , further comprising:
 eighth program instructions to dynamically adjust the threshold resource consumption rate according to a higher fee associated with the ancillary resources associated with either the volatile memory in the second computer or the local hard drive in the first computer; and wherein   
       the eighth program instructions are stored on the computer readable storage media.
