Can I attach two HP server with MLS6060 library

Hello,

I'd like to install new MLS6060 library with 4 drives and connect to 2 servers( rp7420 and L2000) directly. L2000 has DP 5.1 on it.

DP 5.1 is supporting MLS6060? Any other part do I need to connect MLS6060 to two servers?

Could you give any other advice before I order those equipment?

Thank you in advance

Re: Can I attach two HP server with MLS6060 library

for a direct attach (scsi cable connection) you can connect the robotic controller plus two drives to one server (Cell server in DP) and connect the other two drives to the second server, loading an agent for DP.

Hi Marino,

Thank you for your info.

I'd like to connect MLS with Fiber connection. Do I need any extra part for fiber connection? I think Fiber connection is better than SCSI connection. What do you think?

Thank you again.

Re: Can I attach two HP server with MLS6060 library

Hi Jeongbae,

If the library is SAN connected with a NSR e1200-160 (see http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US&prodTypeId=12169&prodSeriesId=316024〈=en&cc=us), both the robot arm and all of the drives can be used by any server that is SAN connected too.

You need following parts: the NSR router, a 2Gb LC-LC cable and a GBIC for the SAN switch

best regards,
Kurt

Re: Can I attach two HP server with MLS6060 library

ah, ok,

Yes you can use the MSL6060 connecte in FC with two servers, I hope you already have a SAN, because for that you need at least one switch, and you need also to ad a NSR(router) to the MSL and a FC HBA in each server.
When istalled these components, you can share your MSL library with all the server you need.

Hi Jeongbae

1. If you have two servers on SAN, you need following:
NSR router for Tape library, one GBIC for SAN switch and one Fiber Cable LC-LC 2mts

2. If SAN is not in place:

NSR router for Tape library, two FC HBAs for servers, one SAN switch ( say 8 ports), 3 GBICs and 3 Fiber Cables LC-LC

You can use FC from the servers to a FC/SCSI bridge that will then connect to the drives using SCSI.

If you cable it this way both servers will have access to all 4 of the drives and the robot.

Re: Can I attach two HP server with MLS6060 library

The library will have 5 scsi connections, 1 for each drive and 1 for the robot.

If you want to do fiber connect make sure you order the fiber options. This will give you the fiber to scsi router mentioned above. You will need two fiber connections and two fiber routers. One router will connect to 2 drives, the other to the other 2 drives and the robot.

I typically configure the library so that the cell server has sole control of the robot but the drives can be accessed by any server. You need to configure DP to use lock names to ensure that two servers do not try to access the same drive at the same time.

If you don't want to use fiber, you could scsi attach some drives to one server and the robot and the other drives to the other server. DP will be able to handle this configuration. The system controlling the robot will mount the tapes for both systems.

Re: Can I attach two HP server with MLS6060 library

Thank you all.

One thing is not clear to me is that we do not have SAN environment yet. Do I need to have a switch to connect from a NSR e1200-160 to two HP servers? I saw a picture of NSE e1200-160 but it has only one fiber channel port.
Any other suggestion for new configuration?

Thanks

Jeongbae,

If you do not have a SAN environment yet, the investment will be a bit high: a SAN switch, GBIC's, fibre cables and FC HBA for the servers.

All of this is required if you want to use the library from two servers.

Maybe a backup through LAN with DP will do the job as well (slower of course but a lot cheaper).

best regards,
Kurt

Re: Can I attach two HP server with MLS6060 library

You do not need to build a SAN to share the drives between 2 servers. You can use the FC/SCSI bridge.

Re: Can I attach two HP server with MLS6060 library

Jeonqbae,

As I mentioned above, You'll need 2 NSRs to support the 4 drives. You could connect 1 NSR to each server, but that would only allow each server to access 2 of the drives.

If you weren't planning to go with a SAN in the future, I would simply go scsi all the way.

That would save you the cost of the HBAs in the server and two NSRs. You'd still need scsi ports in the servers and cables.

The scsi approach would provide the same connectivity as fiber to two NSRs.

Without the SAN switch, you cannot share drives between server.

I that that back. You might be able to use a AL loop topology to connect the NSR and an HBA in each server. I'm not sure if this is supported or how you would cable it.

Anyone, have any thoughts on an AL with two servers and an NSR?

Re: Can I attach two HP server with MLS6060 library

Thank you all for continuous input.

I talked with one of 3rd party vendor and their tech person tell me that the tape library has one Fiber port to handle two Ultrium drives and to handle 3rd and 4th Ultrium drives I need to have MSL e1200 Fiber Kit.

So, The library has two fiber ports which can be connected to both server.

Below is the list of part name.
HP MSL6060 2 Ult 960 Dr FC Tape Library
MSL e1200-160 Fibre Card Kit.

Do you think it is right statement?

Thank you

Re: Can I attach two HP server with MLS6060 library

You have Ultrium960 tape drives in your MSL? I would think more than one tape drive per e1200-160 is overly optimistic.

I would think you'd need four NSR's (that's what the fibre cards are called, and I do not know if any actually come "with" the MSL) to support four Ultrium960 tape drives.

I believe we finally have a FC-native Ultrium960 drive. Would you not be getting those in your MSL?

Looking at that part list, looks like you're getting a two-drive MSL which comes with one NSR, and adding a second. Which would be one drive per NSR. The robotics would connect to one NSR, thus one server would control the robotics and each server would have a specific drive for it to use directly.

Thanks,

Re: Can I attach two HP server with MLS6060 library

Scott:

I think the ESL libraries support native FC drives but based on the last spec sheet the MSL is still scsi.

I was also concerned about driving two
LTO-3 drives through a single NSR, but that is how the configuration guide and MSL options are set up.

If HP is going to update this, Please let me know.
