Abstract
A management method for a storage system is disclosed. The storage system comprises a plurality of hard disks, the management method comprises dividing the plurality of hard disks into a hot storage group, a warm storage group and a cold storage group according to a first threshold and a second threshold; exchanging a first warm storage hard disk conforming to the first threshold in the warm storage group with a hot storage hard disk in the hot storage group in response to not conform to the first threshold; and exchanging a cold storage hard disk conforming to the second threshold in the cold storage group with a second warm storage hard disk in the warm storage group in response to conform to the second threshold.
Claims14
A management method for a storage system, wherein the storage system comprises a plurality of hard disks, the management method comprising:
- dividing the plurality of hard disks into a hot storage group, a warm storage group and a cold storage group according to a first threshold and a second threshold;
- exchanging a first warm storage hard disk conforming to the first threshold in the warm storage group with a hot storage hard disk in the hot storage group in response to not conform to the first threshold;
- and
- exchanging a cold storage hard disk conforming to the second threshold in the cold storage group with a second warm storage hard disk in the warm storage group in response to not conform to the second threshold.
A storage system, comprising:
- a host, comprising a plurality of hard disks;
- and
- a controller coupled to the host, for executing a management process, wherein the management process comprises:
- dividing the plurality of hard disks into a hot storage group, a warm storage group and a cold storage group according to a first threshold and a second threshold;
- exchanging a first warm storage hard disk conforming to the first threshold in the warm storage group with a hot storage hard disk in the hot storage group in response to not conform to the first threshold;
- and
- exchanging a cold storage hard disk conforming to the second threshold in the cold storage group with a second warm storage hard disk in the warm storage group in response to not conform to the second threshold.
A storage system, comprising:
- a host, comprising a plurality of hard disks;
- and
- a controller coupled to the host, for executing a management process, wherein the management process comprises:
- dividing the plurality of hard disks into a first group and a spare group according to a predetermined condition;
- substituting a first spare hard disk in the spare group for a first hard disk in the first group in response to not conform to the predetermined condition;
- and
- indicating to change the storage system when an amount of hard disk included in the spare group is zero.
