Abstract
Abstract A method is provided for interfacing with a storage device having a tape medium. The method includes receiving data from a first source, and creating a first data packet having at least a portion of the data from the first source. The method also includes receiving data from a second source, and creating a second data packet having at least a portion of the data from the second source. The method further includes receiving additional data from the first source, and creating a third data packet having at least a portion of the additional data from the first source. The method still further includes transmitting the first data packet, the second data packet and the third data packet to the storage device, and storing the first data packet, the second data packet, and the third data packet on the tape medium in an interleaved configuration. A system including control logic is also provided for performing the method.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
220 words
A method for interfacing with a storage device having a tape medium, the method comprising: receiving data from a first source during a first time period; creating a first data packet comprising at least a portion of the data from the first source; receiving data from a second source during a second time period; creating a second data packet comprising at least a portion of the data from the second source; receiving additional data from the first source during a third time period; creating a third data packet comprising at least a portion of the additional data from the first source; transmitting the first data packet, the second data packet, and the third data packet to the storage device; and storing the first data packet, the second data packet, and the third data packet on the tape medium in an interleaved configuration, including: storing the first data packet at a first location on the tape medium; storing the third data packet at a second location on the tape medium adjacent to the first location, and storing the second data packet at a third location on the tape medium adjacent to the second location; wherein said first data packet, second data packet, and third data packet are created and transmitted to the storage device without storage on an intermediate disk medium.
Claim 2
Independent Claim
220 words
A method for interfacing with a storage device having a tape medium, the method comprising: receiving data from a first source during a first time period; creating a first data packet comprising at least a portion of the data from the first source; receiving data from a second source during a second time period; creating a second data packet comprising at least a portion of the data from the second source; receiving additional data from the first source during a third time period; creating a third data packet comprising at least a portion of the additional data from the first source; transmitting the first data packet, the second data packet, and the third data packet to the storage device; and storing the first data packet, the second data packet, and the third data packet on the tape medium in an interleaved configuration, including: storing the first data packet at a first location on the tape medium; storing the third data packet at a second location on the tape medium adjacent to the first location, and storing the second data packet at a third location on the tape medium adjacent to the second location; wherein said first data packet, second data packet, and third data packet are created and transmitted to the storage device without storage on an intermediate disk medium.
Claim 3
Dependent Claim
27 words
The method of claim 1 further comprising: retrieving the first data packet from the tape medium; and transmitting the retrieved first data packet to the first source.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein the first source comprises an application program.
Claim 5
Dependent Claim
13 words
The method of claim 1 wherein the first source comprises a system utility.
Claim 6
Dependent Claim
14 words
The method of claim 4 wherein the first source comprises a disk backup utility.
Claim 7
Dependent Claim
24 words
The method of claim 1 wherein the at least a portion of the data from the first source comprises a predetermined amount of data.
Claim 8
Dependent Claim
26 words
The method of claim 1 wherein creating a first data packet includes encoding the at least a portion of the data to identify the first source.
Claim 9
Dependent Claim
32 words
The method of claim 1 wherein the data from the first source, the data from the second source, and the additional data from the first source are received in a multiplexed fashion.
Claim 10
Dependent Claim
57 words
The method of claim 8 wherein the data from the first source, the data from the second source, and the additional data from the first source are received at a first rate and the first data packet, the second data packet, and the third data packet are transmitted at a second rate greater than the first rate.
Claim 11
Independent Claim
257 words
A system for data storage, the system comprising: a storage device having a tape medium; and a control logic operative to: receive data from a first source during a first time period and create a first data packet comprising at least a portion of the data from the first source; receive data from a second source during a second time period and create a second data packet comprising at least a portion of the data from the second source; receive additional data from the first source during a third time period and create a third data packet comprising at least a portion of the additional data from the first source; transmit the first data packet the second data packet, and the third data packet to the storage device; and store the first data packet, the second data packet, and the third data packet on the tape medium in an interleaved configuration, wherein the control logic, to store the first data packet, the second data packet, and the third data packet on the tapes medium in an interleaved configuration, is operative to store: the first data packet at a first location on the tape medium; the third data packet at a second location on the tape medium adjacent to the first location, and the second data packet at a third location on the tape medium adjacent to the second location; and wherein said first data packet second data packet and third data packet are created and transmitted to the storage device without storage on an intermediate disk medium.
