Hi,

RMALS and BE server shared a same tape library via SAN switch. Can BE server and RMALS both use the tape liabrary by using SSO license? 

Thanks!

Richard

Yes this is supported as well. Check the compatibility guide to make sure the Hardware in use is also supported

Thanks. Then how can I monitor the backup data to check if it go through LAN or through SAN?

...check the speed @ which it runs. Or check your NIC.

Thanks!

Sorry CraigV, I am Slightly puzzled by your comment abouth the media server must run Linux - Backup Exec media servers ONLY run on Windows operating systems. RMAL itself must run on a supported version of Linux (which is not necessarily the same as the list of what RALUS supports.)

...just sat back down @ my desk, but I read something a bit misleading on the link posted above, so I have edited my comment out.

Thanks!

Colin: This is what I don't understand (taken from the link that Jaydeep posted):

Ensure that the storage device that is attached to the Linux server is supported. Also, confirm that the operating system can access the device before you start the RMAL.

So does this mean that the server you want to backup using LAN-free methodology needs to have a tape library attached to it? In which case does this even work if the media server runs Windows?

Thanks!

I'll try to answer this -

1. The linux Server on which you need to install RMAL needs to be a supported version on Linux for RMAL Installation. This can be found from Software Compatibility List

2. The Tape Drive that you are connecting via SAN Switch needs to be supprted for 3 things - Supported as Fibre connected device on Media Server, Supported as Fibre attached Tape Drive for use with RMAL and Supported for usage with SSO. This can be found from the Hardware Compatibility List

Thanks for this...so backing up a Linux server using RMAL is supported with SAN SSO then?

This should work. Here is an extract from the 2010 admin guide -

Media servers can share the following types of storage:
■ Devices that are attached to an NDMP server
■ Deduplication storage folders
■ OpenStorage devices
■ Remote Media Agents
■ The remote agents that are configured to send data directly to a storage device

@jaydeep - By Remote Media Agents, I interpret it to mean a RMALS with attached devices, like tape library/drive.  So, if ServerA is a RMALS server with a tape drive, ServerA can be shared by 2 Windows media server.

MediaServer1 -----> RMALSServerA <----- MediaServer2

However the situation described by the OP is different.  He is asking whether a RMALS server can share a tape library with another Windows media server.  

MediaServer1 ------> Tape drive <------ RMALSServerA

I don't understand how this situation is covered by what you have quoted because a RMALS server is not quite the same as a media server.  

1) Does a RMALS server has the SSO capability?

2) Assuming that RMALSServerA is controlled by MediaServer1, how does MediaServer1 knows that the tape drive attached to it is the same tape drive attached to RMALSServerA?

3) Assuming that RMALSServerA is controlled by MediaServer2,

MediaServer1 ------> Tape drive <------ RMALSServerA <------- MediaServer2

how does MediaServer2 knows that the tape drive attached to the RMALServerA is also attached to MediaServer1?  Also, how does MediaServer1 and MediaServer2 avoid writing to the tape drive at the same time.

So my very first understanding is right, RMAL can share BEWS tapes with SSO, then I can backup RAC on Linux via LAN-Free. I need to open another topic to ask my original question, which is an issue when backup RAC with RMAL LAN-Free. Thanks all.

As there was a huge discussion on this thread, I have once again re-confirmed things.

Scenario 1 Which was posted by the RichardQui

MediaServer1 ------> Tape drive <------ RMALSServerA (Managed by MediaServer1)

This is supported and works. However, this will also work without SSO.

Scenario 2 Which was posted by pkh Multiple Media Servers in scenario 1
MediaServer1 ------> Tape drive <------ RMALSServerA <------- MediaServer2

This is supported as well. However, you will need an SSO installed for this. The device handling and management should be handled by Primary SSO server as ADAMM is shared.
