Well some chips have XOR DMA engines, which can make raid5 quite fast without using much CPU. Some have crypto engines that can offload work for ipsec and openvpn. So it depends on exactly which chip. In the case of teh qnap ts-420, the CPU is a marvell 6282, which has XOR DMA engines, and supposedly some security engine. Raid5 should be quite good. Not sure what the support for the security engine is like in linux or what the performance is likely to be if it is supported. -- Len Sorensen -- To UNSUBSCRIBE, email to debian-arm-requ...@lists.debian.org with a subject of "unsubscribe".

Re: Will it work for QNAP 420?
I can't imagine that would be a problem. I'm running samba + raid1 on a 5-year-old (ish) ts-209 without any problems. It's got a 500 MHz CPU iirc. My only issue is that I only get about 1 MB/s throughput on a Gbit LAN. But I haven't yet had the time to isolate the issue, so I'm not sure the problem is with the ts-209. Even my Asus rt-n66u router can do samba+transmission+openvpn (not tried it though), so you should be fine. /B On Tue, Aug 27, 2013 at 1:04 PM, George Sedov wrote: > Hi guys, > > Thanks for your replies. > > I have another question: everybody tells me that ARM processors are a > way too slow for raid5+samba+transmission+openvpn, but the only > information I got on ARM's performance is that Marvell's 1.6 GHz > kirkwood chips are close to atom N270. > > I guess you have some practical experience with ARMs, can you tell me if > Marvell's chips will be able to run all these tasks? > > Cheers, > George > > > В Сб, 24/08/2013 в 08:39 +0200, Martin Michlmayr пишет: > > * George Sedov [2013-08-23 19:27]: > > > 1) First of all, will it work? > > > > Yes, see http://www.cyrius.com/debian/kirkwood/qnap/ts-41x/ > > > > > 3) Can I install rootfs not on the SATA drives, but rather on the usb > > > flash-stick, thus leaving all of the drives completely system-free? > > > > Yes, that's supported. > > > > > 4) Will I manage all this without any experience with debian? :) I used > > > gentoo for several years though. > > > > As long as you have experience with Linux, you should be fine.

Re: Will it work for QNAP 420?
Hi guys, Thanks for your replies. I have another question: everybody tells me that ARM processors are a way too slow for raid5+samba+transmission+openvpn, but the only information I got on ARM's performance is that Marvell's 1.6 GHz kirkwood chips are close to atom N270. I guess you have some practical experience with ARMs, can you tell me if Marvell's chips will be able to run all these tasks?
