additional FWD SCSI card on k260

Hi,

i having a k260 box which equip with one core I/O board and one HP-PB I/O Board (sitting next to core I/O). i got a refurbish FWD scsi card (28696-69104 Fast Wide Differential SCSI Host Adapter Board) but my current HP-PB I/O is full. Question:

1. how i know whether i can add another HP-PB? can i check from console or hav to phisically check from rear slot?
2. i found the expansion I/O slot was empty. can i use it for scsi?
3. does FWD scsi card come with single height? the card i having is double.

Re: additional FWD SCSI card on k260

I believe a K260 has room for 2 full height expansion cards so you can add your double height SCSI card right next to the current one. You cant get a single hieght HP-PB FW-SCSI card, only a double-height (you can get a single height HP-PB SE scsi card though).

From the back unscrew the cover plates (x2) right next to your existing HP-PB card and you will see there is a connector to plug it in when you can get some downtime to shutdown the server.

This is the one all our servers have; 28655A
Its a single height SE SCSI (50pin) card. You can fit into each expansion bay 1x single height and 1x double height card.

Hi

28642A: I have no information
28655A: SE SCSI-2 single-height for K-Class

One of my guide says that the K260 can take a maximum of 4 HP-PB cards
two of these may be double-height

Re: additional FWD SCSI card on k260

Those information is really appreciated. My last simple question -- did anyone try the 28655A with any DLT8000 drive before? as i know, the patches PH23790 need to be install for stape driver correction. Other than this, any suggestion or comment?

Re: additional FWD SCSI card on k260

The DLT8000 is probably a FWD device and will not work on a SE scsi card.
There are also DLT8000 units available which are LVD devices but I doubt they will work on SE scsi interface.
Even if you could place your HP-PB FWD card in the system the DLT8000 won't work since the HP-PB isn't fast enough for the DLT8000.
On the core I/O board one can place an extra interface ( A2969A for FWD card ), is this slot used already ?
This A2969A interface is a HSC interface and the DLT8000 will work on this one.

Re: additional FWD SCSI card on k260

i was shock about the DLT8000 wont work with 28655A SCSI-2. im getting a Compaq DLT8000 with LVD/SE interface. what i know if i dont use LVD card, i will get SCSI indeed of LVD speed since my drive is LVD/SE. if DLT8000 only work with HP-HSC slot, why hp make SCSI-2 card for 28655A? Sorry i new to HP product.

Re: additional FWD SCSI card on k260

Hi,

Marcel is right, PB-cards are too slow for the DLT8000 and you cannot connect LVD/SE devices to your K-class.

You need a HighVoltage DLT8000 drive and you need to connect it to the HSC bus (e.g. on Core I/O).

The only other option would be to get a used DLT4000 drive which you can connect to PB SE-SCSI card. This is a typical config. But perfomance is much slower.

Bernhard
