Hello I see it is possible to buy Flash Disks up to 4GB now. Has anyone any experience of building an Asterisk system with a flash disk as the only storage device? Any brands you recommend? Is 2 or 4GB enough for an Asterisk installation? Typically how many MB is required for voicemail recording files for say a 10 user system? What about voicemail - I suppose files could be emailed and deleted immediately? Angus Comber angus@NOSPAMiteloffice.com -------------- next part -------------- An HTML attachment was scrubbed...

Greetings, We have a solid state Asterisk server provided by The VOIP Connection that uses a 512MB Compact Flash device as the primary boot device as well as the main storage device and it works fine for us. The system isn't the fastest booting, but the technology is absolutely sound. Make sure that you have a solid disaster recover/backup process for this thing though.

You will want to make sure that you don't install general purpose distros onto compact flash cards without taking into consideration the (somewhat) limited number of Compact Flash write cycles. Compact flash can burn out if you write too much, and I fear that the other solutions out there do not take this into account. As far as actual CF cards, I can't recommend anything other than Sandisk. On my AstLinux-Users mailing list, shoddy CF's are probably the most common problem. Everything from bad IDE emulation to poor reliability, just get Sandisk. They don't mess around with CF cards! :) -- Kristian Kielhofner

I have a Kingston Tech flash disk that was flaky and finally failed yesterday. They are not the fastest - running hdparm -tT on them reveals a speed of 2Mb/s which is about a third of the speed of 100Mbits ethernet. For call recording I usually add an IDE hard drive and make sure that most filesystems (e.g. /var,/tmp..) are loaded into a RAM disk Paul Hewlett -- Paul Hewlett - CottonPickinMinds - www.cottonpickinminds.co.za Tel: +27 21 852 8812 Cel: +27 84 420 9282 Fax: +27 86 672 0563 --
We had an experience with asterisk in a 512 MB IDE Compact Flash card. It uses nearly 400 MB of storage with a minimum installation of Linux, and 2.6.10 Kernel. I has web access with AMP Portal with needed modules as apache, php, etc. But the size can be less. It works fine. You can search about embedded asterisk. There are quite doc on the web. Regards.

What problems were you having? CF is both slow and fast. Seek times are very low, but sustained data transfer rates are not very good (ESPECIALLY for writes). 2Mb/s is actually more like 1/4 - 1/5 the speed of 100mbps ethernet... Are you aware that I have created a distro specifically for running Asterisk from compact flash? Perhaps you should take a look: http://www.astlinux.org -- Kristian Kielhofner

Any brands you recommend?Beware that some flash producers sacrifice seek speed for transfer speed. This is okay for most usages, but not for harddrive-usage.
