Filed:

Jul 12, 2002

Appl. No.:

10/194685

Inventors:

Vy Nguyen - Hayward CA, US

Assignee:

3PARdata, Inc. - Fremont CA

International Classification:

G06F013/00

US Classification:

710100, 710123

Abstract:

A method for new nodes to join a cluster in a serial sequence includes (a) a new node transmitting a first type of request to join the cluster and (b) the new node determining if it has to back off the first type of request. The new node has to back off if (1) it has received a second type of request to join the cluster from another new node, (2) it has received the first type of request with a higher sequence number from another new node, (3) it has received the first type of request with a lower node number from another new node, or (4) a member node of the cluster is in a busy state. The new node transmits the first type of request, receives the first type of request, and receives the second type of request through primary links to the new nodes and member nodes of the cluster.

US Classification:

719318, 714 1, 714 2, 714 4, 714100, 709223

Abstract:

A method for notifying events to a node in a cluster includes (1) receiving a first event message and a second event message, (2) queuing the first and the second event messages, (3) sending the first event message to a first service callback, wherein the first service callback calls a first callback function to handle the first event message, (4) sending the first event message to a second service callback after (a) a the first service callback has handled the first event message and (b) a corresponding first service callback at a member node has handled the first event message, wherein the second service callback calls a second callback function to handle the first event message, and (5) sending the second event message to the first service callback after the first and the second callback functions have handled the first event message, wherein the first service callback calls the first callback function to handle the second event message. The method may further include sending a dummy message to the first callback function if the first callback function is waiting for a message from a sending node that is down. The method may also include sending a node down message to the first callback function if the first callback function is sending a message to a receiving node that is down.

International Classification:

G06F 15/177
G06F 9/54

US Classification:

719313, 719315, 709203, 709221

Abstract:

A method for a name mapping module on a node to handle communication between a client process and a server process includes receiving from a client process a process handle and a message for a server process, mapping the process handle to an entry of the server process in a process table, reading the entry to retrieve (1) a node number of a node and (2) a process ID on the node, and sending the message with the process ID to the node. If the server process is not accepting messages, the method further includes waiting for the backup server process to take over for the server process before sending the message. If the server process or the node fails after the message was sent, the method further includes waiting for the backup server process to take over for the server process. 217.

International Classification:

A47C 27/06

Abstract:

This disclosure addresses mattresses. The mattress includes a core made up of multiple zones. Each of the zones includes a plurality of core elements, the core elements being formed from at least one wire coil spring at least partially contained in a fabric pouch. The core elements are typically joined in linear chains. The zones vary in support firmness according to the selection of a user. The core elements include wire coil springs formed from wires of at least two different sizes, and of at least two different heights.
