Straight from Cisco:
"Digital subscriber line (DSL) is a modem technology that uses existing twisted-pair telephone lines to transfer high-speed data. Many types of DSL are used today; the most common are asymmetric DSL (ADSL) and symmetric DSL (SDSL). ADSL provides a higher downstream speed than upstream. SDSL provides the same speed for both upstream and downstream traffic."
Right. It would sure be nice if the amd64 releases of FreeNAS 0.7 are continued (apparently, there's a kernel panic upon bootup preventing them from releasing the amd64 alpha versions). The current i386 version is limited to 512MB of kmem (unless the kernel is recompiled), which is DEFINITELY not enough for ZFS (even a 1GB allocation is insufficient). With my max allocation at 512MB, I've had the kernel panic about 5 times in one day while transferring large amounts of data.
My advice to those of you who are using ZFS in FreeBSD: set the vm.kmem_size and vm.kmem_size_max in
