| Q1. |
How can I analyze my SAN using SAN Visibility? |
| A1. |
- SAN Visibility is a quick and easy way to view and analyze your SAN topology and components.
- It can be used as an inventory management tool in data centers.
- It discovers switches and hosts, collects data from your SAN and sends the data for analysis through e-mail.
- To analyze your SAN, collect SAN data using SAN Visibility and send the raw data (".hp" file) to SAN_Visibility@hp.com for processing.
-
The collected data is then processed and a report is generated and is emailed to your email address.
The report sent to you includes:
- SAN topology diagram.
- High level SAN summary.
- Device inventory.
- Connectivity details of FC switches, Hosts, HBAs and Storage Systems.
- Driver and firmware recommendations for HBAs and FC switches.
- Compatibility analysis of SAN components and zones.

| Q2. |
What the pre-requisites are for switch and hosts discovery? |
| A2. |
You need to know the IP address of switch and host and ensure that SSH is running and password authentication is enabled for UNIX hosts.. To enable password authentication, set passwordAuthentication in /etc/ssh/sshd_config file to yes and restart the ssh service.

SAN Visibility provides the following data security features:
- SAN data that you send to and receive from HP is encrypted.
- The data you send to HP for processing is encrypted and stored in a restricted environment.
- You have an option to view and verify the data before sending it to HP for processing.
- You can mask the IP address of the switches in your SAN using "Mask IP address" feature available with SAN Visibility. What that means is that you can restrict SAN Visibility to send your IP address outside your network. To hide the IP addresses, select "Mask IP address" option present in the Data Collection window.
Selecting this option, hides the IP addresses of all the switches present in your SAN in the processed report.
