Re: Ultra 10 max HDD capacity?
I have a 120 GB drive in my U10. I have seen reports from people who have larger drives (IOW, drives larger than the normal 128 GB limit that is seen on older x86 hardware) in their U10s and/or U5s. I've always been too lazy to yank the 200 GB out of my SFF and try it in my U10. The SFF is more a pain to work on than the U10. I believe that my 120 GB drive supports udma2 or udma3, at least, but in practice it runs at mdma2. Judging from comments I've read since I acquired my U10 a year ago, I believe that the lack of DMA is due to either: 1. DMA is not supported by the IDE hardware that Sun provides -- or -- 2. DMA is supported by the IDE hardware, but it is so buggy/misfeatured that the kernel does not support it in either the 2.4 or 2.6 versions. This may mean that DMA is unsupportable or it may mean that no one with appropriate knowledge can dedicate the time to make it work. Not having DMA seems to mean that you will only get about 13-15 MB/s (via hdparm) when using the IDE hardware provided with the U10. This is OK for me, since this is a server and I'm only running 100 mbit/s ethernet to it. The ethernet will saturate before the drive will run out of bandwidth. The usual suggestions for improving the low data rate are: 1. Buy SCSI hardware. This is expensive, particularly for medium-sized or large drives. 2. Buy an IDE or SATA PCI card and an appropriate drive. These suggestions are complicated by the fact that not all SCSI/IDE/SATA PCI cards will work on Sun hardware. Sun does have a compatibility list on their website, but it can be hard to know who made the chips you are getting when purchasing cheap/no-name PCI cards. I have seen someone suggest that hardware that works with Apple PPC hardware is also likely to work with Sun hardware. -- darin --- Josip Rodin [EMAIL PROTECTED] wrote: On Tue, Feb 28, 2006 at 06:18:16AM -0800, Bruce Harrison wrote: Is this the same for an Ultra 5 Sparcstation?

Re: Ultra 10 max HDD capacity?
Hi Bruce, The Ultra5 is a machine with a very strong and somewhat unpredictable personality... I tried a Hitachi 80G's and Maxtor 100G's on two ultra5s (333 and 400 Mhz) and they were accepted without any problem, both in Debian 3.01 and Aurora 1.92. The machines refused a Seagate 40015. Maybe after having tasted the 100G, they considered the 40er as humiliating... On the other hand, we can see regularly on ebay ultra5s sold with 120G drives. This suggests that in principle, there should be no problem.. Cheers, Joseph --- Bruce Harrison [EMAIL PROTECTED] wrote: Hello All! Is this the same for an Ultra 5 Sparcstation?

Re: Ultra 10 max HDD capacity?
The physical limit is 137Gb, which effectively limits you to the nearest normal size of 120Gb. I have a 120Gb drive working OK here. For more capacity you would need to go to external SCSI devices.

Sun suggest that the max HDD capacity for Ultra 10's is 20.4 Gb, is there any reason why (under linux), we can't use bigger? I don't need bigger, but it's easier to buy big than small, these days. this has been discussed numerous times on the sun-managers list, but I don't recall the answer. Guessing, I'd say the ATA-5 limit applies, ie 120-130 Gb or so. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
