System setup

[Jayesh shah]

Hi,
I require some help in setting up a small Lab.

I have the follwing machines :

K-Class/K460PA server with 2 F/w differential SCSI ports

K-Class/K460 PA server with
one 16-bit diffferentail SCSI port
one F/W differentail SCSI port
three HSC FC 266 mbps shortwave ports

D-class/9000 PA Risc server with
one SCSI single ended port

Visualize J2240 PA server with
one ultrawide SCSI single ended port
one SCSI-2 single ended
one SCSI LVD single ended


Now the peripheral devices:
NIKE 20 :SCSI -A 2ports & SCSI-B 2ports
ICE Autoraid:2 SCSI ?
MUX:2 FC 1062 mbps shortwave port
& 2 differential SCSI

CRONUS disk array(HP surestore E 7405):
2 FC ports (2 Disk FC , 2 Host FC ,RS 232 serial)

Jamaica:
4 SCSI ports

DLT 40 Tape drive: SCSI single ended

DLT 4000 : Differential SCSI

Megatron : SCSI A -2 ports ,SCSI-B 2 ports

FC10 (Disk surestore E):4 Fc ports

Optical Disk drive 1300T:SCSI?

I require help in finding out the connections between the peripherals and the machine .Also I require help in finding out if I require additional Fc ports on any machine (We can add additional Fc card on K-class and visualize J2240).Also information on the cable required.

Waiting for reply

Thanks,
Shah

Well, there's a lot there..
the Nike 20 is FWD scsi.
The 2 ports are a scsi in and one is a scsi bus extender. SCSI is a bus so there is an in and an out. You can put up to 16 devices (including the host) on a scsi bus.

Fibre, on the other hand is a loop not a bus. You can't really 'extend' the loop without a fc hub/switch or tearing the cables in two.

The tx of adaptor1 goes to rx of adaptor2 and tx of adaptor2 goes to rx of adaptor1.. This is why it's a good idea to have a hub there.. without the hub you can only have, supported have, two interconnected fc devices, one of them being your host.

The hba's you describe I believe are not compatabile with your devices. You need 1063 Multimode Shortwave HBAs - 1GB/s... and the cables will correspond to that.. you may be able to reuse your cables.. I don';t know for sure though I never worked with 256MHz fibre.

The FC10 you have only needs one LCC, unless you're thinking of buying another FC10 in the future or adding multihost failover. You only need one GLM in it too, although I'd recommend keep the other as a quick replacement part.

I'm not sure if I answered your question fully, but I hope you gather something from this at least!
Later,
Bill

Hi,

What is your goal here?
You have a set of machines and peripheral devices but what is it that you are trying to achieve here?

You have a NIKE array and an autoraid, do you want this shared between machines? Are you setting a MC/SG cluster?

Looking at the configuration you gave, looks like you are planning to set up a MC/SG cluster for the K's with the shared data on the NIKE/Autoraid and the MUX connected between the K's as well. The DLT will probably go to the back up server (the D/Visualize) but you will have to give more information about your goal here.

Also I think Bill deserved more points, because he tried to answer your question given what you have told us so far ( but that's my $0.02)

Ramesh

My goal is to setup a test lab.We are proceeding along the following lines:

1.K-class/K460PA:
Nike 20 disk array connected to F/W SCSI port
ICE Connected to MUX to SCSI Differential port

2.Visualize J2240 PA:
DLT 40 connected with SCSI SE
Megatron connected with SCSI LVD
(4 ports are available on megatron :rest are terminated)
CRONUS connected via FC port(needed)

3.K-class/PA RISC/K460:
DLT 4000 connected via F/W SCSI to 16 bit differential
SureStore FC10 to the HSC port (compatible cable required ?)

4.D-class/9000 PA Risc:
Jamaica to SCSI SE (will not have hot swap enabled)
Optical Drive 1300T to SCSI SE ?

We are not hundred percent sure of these configurations.

Thanks,
Shah
