Abstract
Methods, apparatus, and products are disclosed for implementing a redundant array of inexpensive drives (‘RAID’) with an external RAID controller and hard disk drives from separate computers, including configuring by the external RAID controller a RAID array, the RAID array comprising hard disk drives from the separate computers, the external RAID controller comprising a hardware RAID controller installed externally with respect to the separate computers, and storing, by one or more of the separate computers through the external RAID controller, computer data on the RAID array.
Claims18
A method of implementing a redundant array of inexpensive drives (‘RAID’), the method implemented with an external RAID controller and with hard disk drives from separate computers, the method comprising:
- configuring by the external RAID controller a RAID array, the RAID array comprising hard disk drives from the separate computers, the external RAID controller comprising a hardware RAID controller installed externally with respect to the separate computers;
- and
- storing, by one or more of the separate computers through the external RAID controller, computer data on the RAID array.
Apparatus for implementing a RAID array, the apparatus comprising an external RAID controller and hard disk drives from separate computers, the apparatus further comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:
- configuring by the external RAID controller a RAID array, the RAID array comprising hard disk drives from the separate computers, the external RAID controller comprising a hardware RAID controller installed externally with respect to the separate computers;
- and
- storing, by one or more of the separate computers through the external RAID controller, computer data on the RAID array.
A computer program product for implementing a RAID array, the RAID array implemented with an external RAID controller and hard disk drives from separate computers, the computer program product disposed upon a computer readable, recordable medium, the computer program product comprising computer program instructions capable of:
- configuring by the external RAID controller a RAID array, the RAID array comprising hard disk drives from the separate computers, the external RAID controller comprising a hardware RAID controller installed externally with respect to the separate computers;
- and
- storing, by one or more of the separate computers through the external RAID controller, computer data on the RAID array.
