Model SB-3160SI, when to create Volume size, there're options to set stripe size as 64K, 128K, 512K, factory default for stripe size is 64K. The meaning of stripe size is to set up the block size when controller read/write data. If you didn't change the setting about stripe size, then we assumed it's still remained 64K. So when you give dd command to check data read/write by 64K per sector, this is to match stripe size / block size, and the result is no question. But when you give dd command to check data read/write by 72K per sector, this is over 64K block range, and this is why you found the result is likely different. Please note, once the Volume set is created, to change stripe size will cause Volume re-format and data lost. So if you are interested to continuously test the unit by dd command, we suggest you to try 128K or 512K. SB-3160SI working with Adaptec 29160 has no problem to support volume greater than 2TB. 2. The setting of HTTP port lost is caused by firmware upgrade. Please use RS232 cable and connect to Monitor port of controller. Login controller console by "admin", password "00000000". Then you may go and change HTTP port as you wish. Best regards, Maxine Chen Assistant Manager / Overseas Sales Dept. Proware Technology Corp.

Oh. It's just that md5 sums are different when I've been writing 72k chunk. How different doesn't matter now, does it? To explain further: > > # dd if=/dev/random of=/tmp/test.rand bs=72k count=1 This creates /tmp/test.rand file, 72kB in size, filled with random bytes. > > # dd if=/tmp/test.rand of=/dev/da6p2 bs=72k count=1 This writes 72kB block of data, taking source from the file and outputting it on the disk. > > # dd if=/dev/da6p2 bs=72k count=1 | md5 This reads that 72kB block of data back from the disk and calculates md5 sum of it. > > # md5 /tmp/test.rand This calculates md5 sum of the file used as source for writing to the disk. If all were fine, those md5 sums would be the same (as is the case when writing 64kB chunks). I could not test with different controller, though. :( If you have freebsd with different controller and such array and writing above 2TB barrier works fine for you, this would indicate it is not the problem with the Simbolo and I will try to get different controller. > 2.

I don't have a problem with that, too. :) > 3. Re IP change : > When you are able to login GUI manager, please go to "EtherNet > Configuration" and you will be able to change IP for HTTP and Telnet. And I know, how to change that as well. :) Issues I found were only with LCD panel menu slight deficiency, which I had no problems resolving in other way (via serial console, to be exact), just thought I would mention it to you, perhaps you would consider them for fixing (especially being unable to set http port after upgrade when it's default "0", not "80", was weird experience). Thanks for the answer, though. :) p. -- Beware of he who would deny you access to information, for in his heart he dreams himself your master. -- Commissioner Pravin Lal -- This message has been scanned for viruses by MailScanner, and is believed to be clean. --
