Continuous Access Storage Appliance Installation and Maintenance Guide

Processing synchronous IP mirroring requests

This section describes how the appliance software processes synchronous IP mirroring 
requests. It describes the following topics:

■

Synchronous IP mirroring process

■

IP mirroring performance

Synchronous IP mirroring process

Processing synchronous IP mirroring requests involves the following steps (

Figure 28

):

1. The host sends a request to the local LUN.

2. An IP mirroring worker thread receives the request on the local LUN and sends it to a 

network thread on the remote LUN. 

3. The worker thread completes the request on the local LUN.

4. A worker thread completes the request on the remote LUN.

5. The local LUN waits for a successful response from the remote LUN.

6. The worker thread on the remote LUN sends a successful response to the worker thread on 

the local LUN. 

7. The worker thread on the local LUN receives the response from the remote LUN.

8. The local LUN sends a response to the host indicating that the request is complete.
