and of course the correct fibre cables of the correct specification (there are several/many different cable types - and you will need to get 'exactly' the right type), with the correct 'plug' ends to match (i.e. of the correct type (probably SW (short-wave)), and correct speed (probaby 8Gb), and correct specifications (FC SAN and *not* LAN) and correct laser frequency. with FC SFPs already in each port to beused with enough free, unused, but licensed ports
at least one FC switch to use FC tape with FC HBAs If you want to go the FC SAN switch route, then you will need: If you have four single ported tape drives, and you want to use all four tape drives, then you have two choices:ġ) will need either a SAN switch to implement a SAN fabric.Ģ) or you will need an additional dual port FC HBA in your appliance to cable directly between four appliance ports and four tape drive ports. NetBackup will 'see' the other two unused tape drives when it talks to the tape library, but will simply ignore them, no problems. If you have four tape drives and you want to get going quickly, then simply do not cable two of the tape drives, and instead at least get two of the drives working whilst you think about possibly acquiring a SAN switch. Instead, you could forgoe tape multi-pathing, and instead simply cable directly between one port of the appliance, and one port of each tape drive - and therefore no need for SAN switch or SAN zoning. If you have two tape drives, and they are dual ported - then you do NOT need a SAN switch to get this working.

Run the device configuration wizard in the NetBackup GUI.Īnd you should be good to start using the NetBackup 'storage unit' for the tape library (and NetBackup will know that the storage unit has four tape drives).Ģ) Two dual ported tape drives, or four single ported tape drives?Ĥ) Do you have one FC SAN switch with at least 6 free unused but licensed ports?ĥ) Or, do you have two FC SAN switches each with at least 3 free unused but licensed SAN switch ports? Then on the tape library management GUI - present the robot control and tape drives as LUNs to the required WWPN "initiators" (which should auto-popup in the tape library management GUI). With the above, you will have created two zones, each with a single initiator, and each with two targets (tape drives).Īfter this, on the appliance, re-set the HBAs. (BTW - there are other things that you should do first when configuring a new SAN switch - so you'll have to read the guides on that). If it's a new bare bones SAN switch and no pre-existing config, use the 'cfgcreate' command instead of 'cfgadd'. The above assumes you have a 'config' named 'CFG_FAB_A' that already exists. Here's an example for Brocade to zone the two appliance FC HBA ports to four FC tape drives: $ alicreate AL_APPLIANCE1_HBA1_PORT1, "nn:nn:nn:nn:nn:nn:nn:nn" $ alicreate AL_APPLIANCE1_HBA1_PORT2, "nn:nn:nn:nn:nn:nn:nn:nn" $ alicreate AL_TS3200_TAPE1, "nn:nn:nn:nn:nn:nn:nn:nn" $ alicreate AL_TS3200_TAPE2, "nn:nn:nn:nn:nn:nn:nn:nn" $ alicreate AL_TS3200_TAPE3, "nn:nn:nn:nn:nn:nn:nn:nn" $ alicreate AL_TS3200_TAPE4, "nn:nn:nn:nn:nn:nn:nn:nn" $ zonecreate ZN_APPLIANCE1_HBA1_PORT1, "AL_APPLIANCE1_HBA1_PORT1 AL_TS3200_TAPE1 AL_TS3200_TAPE2" $ zonecreate ZN_APPLIANCE1_HBA1_PORT2, "AL_APPLIANCE1_HBA1_PORT2 AL_TS3200_TAPE3 AL_TS3200_TAPE4" $ cfgadd CFG_FAB_A, "ZN_APPLIANCE1_HBA1_PORT1 ZN_APPLIANCE1_HBA1_PORT2" These are your initiator WWPNs.Ĭollect the FC Tape Drive WWPNs from the tape library. I think what you might be "missing" is just how easy SAN "zoning" really is, once you get your head around it.Ĭollect the FC HBA WWPNs from the appliance. My recommendation is a Brocade SAN switch.
AFAIK, no Cisco SAN switches have this feature. Most Broacde SAN switches have feature called 'cut through routing' which can be just great for storage as it completely and utterly eradicates any concept of packet latency. AFAIK, many Cisco SAN switches have port group contention.
#Brocade san switch concepts full
all SAN switch ports can Tx/Rx at full speed at all times with zero bandwidth contention. Most Brocade SAN switches have zero port contention, i.e.
SANs can have VSANs, and you'll have to read up on that - but I doubt very much you will need VSANs - as these are typically used in much larger installatons.
The Cisco 3750 or 3850 are LAN switches, and as far as I know cannot do SAN FC.
