Abstract

A data storage device includes storage media with multiple media zone attributes of storage performance. The storage device includes a data channel that is connectable to a host system. The data channel receives an object from the host system that has a requested storage attribute attached to the object. The storage device comprises an object-based storage interface that couples between the data channel and the storage media. The object-based storage interface schedules the object for storage in a selected zone of the multiple media zones based on the attributes and requested attributes.

First claim

What is claimed is:

1. A method for allocating data attributes from an i-node to storage media, the method comprising:
sending, by a host system, a data object containing i-node attributes to a storage device, wherein the storage device comprises:
a data channel;
an object-based storage interface, coupled to the data channel, wherein the interface is operable to allocate data to particular media zones for storage based on access frequency; and
storage media, coupled to the object-based storage interface, with multiple media zones having differing zone attributes of storage performance, and wherein the zones are physically separate;

receiving the data object through the data channel;
providing the data object to the object-based storage interface;
receiving the data object at the object-based storage interface;
analyzing the data object i-node attributes to determine one or more i-node attribute access frequencies;
allocating to the storage media, by the object-based storage interface, the i-node attributes, based on the one or more i-node attribute access frequencies;
wherein the less frequently accessed portion of the storage media comprises i-node write attributes;
wherein the more frequently accessed portion of the storage media comprises i-node read attributes;

storing the i-node attributes in the allocated zones of the storage media.

2. The method of claim 1 wherein the more frequently accessed portion is stored in an I-node extension.

3. The method of claim 1 wherein the zone attributes are stored in a map that maps the zone attributes as a function of zone physical addresses.

4. The method of claim 1 wherein the zone attributes comprise zone attributes determined from a test of the storage device.

5. The method of claim 1 wherein the zone attributes comprise zone attributes determined from both a test of the storage device and tests of a representative sample of a group of storage devices.

6. The method of claim 1 wherein the object-based storage interface provides data format conversion.

7. The method of claim 1 wherein the storage device comprises stored information on the storage media including throughput per zone and remapped sectors.

8. The method of claim 1 wherein the storage device stores multiple copies of the same object on different parts of the storage media.
