K360 Internal Disk Drive capacity

I have a few old K360's at another location. I need to know what the internal disk capacity of these machines are. They are currently configured with (2) 4 GB drives and I was wondering what my options were in terms of filling it in terms of number of drives as well as the size of the drive.

Thanks

Re: K360 Internal Disk Drive capacity

Your K-360 will support up to 4, 9.1GB internal drives but be aware that these are HVD (Hi Voltage Differential) SCSI devices.


I NEVER used any internal drives on any K-boxes because they are not hot-plugable. All my drives (including boot drives) were always external so that I would not have to shutdown to replace a failed drive.
If it ain't broke, I can fix that.

Re: K360 Internal Disk Drive capacity

Thanks for your reply. We have limited space in the data center as these hosts are racked and external disk devices though not prohibited are generally avoided if possible

Re: K360 Internal Disk Drive capacity

Can you tell me what external disk cabinets and disks (size) that can be added to these K360's?

Once again, thanks for your quick response.

Re: K360 Internal Disk Drive capacity

I have used Jamaica's (HP A3311A, I believe) and FC10's quite extensively with K boxes.

The Jamaica's can hold up to 8 low profile disks of 4, 9 or 18GB. The Jamaica is a SCSI device and can be either SE of FWD (High voltage differential SCSI).

The FC10 can hold up to 10 drives of up to 73GB capacity I believe. The FC10 is a fibre device.

Re: K360 Internal Disk Drive capacity

hi, you can put upto 4x 18gb discs internally in the k's. All HVD scsi disks.
or externally you can use
A3312A rackmount box for 8 drives
A3311A deskside box for 8 drives

SC10(rackmount) for 10 lvd scsi disks but slower performance than you would expect from lvd discs due to speed of interfaces available.

FC10 (Rackmount) which hold 10 discs

or the older M12H array which hold 12 discs.

Re: K360 Internal Disk Drive capacity

Hi Al, the max you can get in your K box is 4 x 180GB FWD drives giving you 720GB total. There are also 36GB drives for the K boxes, that HP part number is A5529A you can usually find them on ebay.

Re: K360 Internal Disk Drive capacity

The most important part about internal disks for K-boxes is that they HIGH VOLTAGE, not just Fast Wide Differential (FWD). Disk mfr's stopped making these disks a long time ago so you'll need to look at the used/resale marketplace to get them. Most people confuse FWD with LVD (Low Voltage Differential, more accurately, FWD-LV). The LVD standard is compatible with class SCSI-SE but FWD-HV is not compatible with any other SCSI standard. The FWD-HV was state of the art in the early 90's because it was 20Mbit, 15 SCSI addresses and could transfer data over dozens of feet of cable.

While Jamaica boxes were really common for external storage, today's disk enclosures are much smaller and take up much less rack space. The DS 2100 is a good example--1 rack space (1.75 inches) for 4 disks...very easy to add to an existing rack.

Re: K360 Internal Disk Drive capacity

I believe the Jamaica are reaching end of life soon. HVD10 (looks like FC1010) are supposed to be the replacement for Jamaica. The HVD10 actually uses LVD disks, which is the same as those on the SC10.

The other FWD product which I can think of are the SmartRacks. I'm not too sure when these will last too!
On the move....

Re: K360 Internal Disk Drive capacity

The options for the K-class are extremely limited, the only current storage available is the FC10. The HVD is an ultra wide solution I don't think it works on the K Chassis. The controllers are really expensive, you could replace that K-class with a B or C class. I think the largest supported internal drive is 18 GB FW, high voltage.

The B and C workstations make for real good replacements of the old K.
