Abstract

Systems and methods for storing data are provided herein using a data archive architecture controlled by a head server. The head server can write data in a contiguous manner across multiple storage devices by partitioning objects into multiple portions and spreading the portions across the multiple storage devices. Portions of a first object can be transmitted to a first subset of storage devices and portions of a second object can be transmitted to a second subset of storage devices. The first subset of storage devices can write the portions of the first object to a first write location indicated by a write pointer. The head server can increment the write pointer based on a length of the portions of the first object to a second write location. The second subset of storage devices can write the portions of the second object to the second write location.

Claims20

Dependent claims

A method to store data sequentially on a media comprising:

receiving, by a head server in communication with a plurality of storage devices, a first object;
dividing, by the head server, the first object into a first portion having a first length and a second portion having a second length, the first length different from the second length;
transmitting, by the head server, the first portion to a first storage device of the plurality of storage devices;
writing, by the first storage device, the first portion to a first write location of the first storage device indicated by a write pointer;
incrementing, by the head server, the write pointer to a second write location based on the first length, the second write location of the first storage device;
transmitting, by the head server, a first subset of the second portion to the first storage device and a second subset of the second portion to a second storage device of the plurality of storage devices;
writing, by the first storage device, the first subset of the second portion to the second write location of the first storage device, the second write location in a contiguous order indicated by a write pointer;
incrementing, by the head server, the write pointer to a third write location of the second storage device;
and
writing, by the second storage device, the second subset of the second portion to the third write location of the second storage device, the first portion and the second portion stored in a contiguous order from the first storage device to the second storage device.

7 more elements

A system to store data sequentially on a media, comprising:

a head server in communication with a plurality of storage devices, the head server configured to:
receive a first object;
divide the first object into a first portion having a first length and a second portion having a second length, the first length different from the second length;
transmit the first portion to a first storage device of the plurality of storage devices indicated by a first write location at the first storage device;
increment a write pointer to a second write location based on the first length, the second write location of the first storage device;
and
transmit a first subset of the second portion to the first storage device and a second subset of the second portion to a second storage device of the plurality of storage devices;
increment the write pointer to a third write location of the second storage device;
and
the first storage device configured to:
write the first portion to the first write location of the first storage device;
and
write the first subset of the second portion to the second write location of the first storage device;
and
the second storage device configured to:
write the second subset of the second portion to the third write location of the second storage device, the first portion and the second portion stored in a contiguous order from the first storage device to the second storage device.
