Comparison OpenBlockS A6 and OpenBlockS AX3¶
I rented OpenBlockS A6 and OpenBlockS AX3 from Plat’Home Co., Ltd.(Thanks!) last early summer. I will write blog post about A6 and AX3 several times. I wrote blog post about comparison of A6 and AX3 at this entry.
Opening ceremony of OpenBlockS A6 and AX3¶
ES version of A6¶
OpenBlockS A6 I rented the first was ES(engineering sample) version. It was exchanged to the product version on the way. The difference of both on the appearance was screws of body. The diameter of the screw hole of product version is smaller than ES version. The storage installed of ES version was ADATA’s 2.5 inch SSD 396 30GB, that of product version was HalfSlim SSD 16GB MLC.

Comaprison v.s. OpenBlockS 600¶
I compare their bodies against OpenBlockS 600. OpenBlockS A3 is slightly larger than OpenBlockS 600.

Filesystem¶
I was formatted storage because The storage of ES version was not formatted. It is the same that case I bought OpenBlockS AX3 J. The storatge of product version was already mounted with UnionFS. It was the same that case I had rented OpenBlockS AX3.

It is /etc/mtab as folloing.

This UnionFS is controlled by “/etc/init.d/openblocks-setup” and “/etc/default/openblocks”. This init script also controls hardware specific to OpenBlockS. Other are the same as a normal Debian system.
OpenBlockS 600¶
OpenBlockS 600 with CF boot is invisible the storage device.
$ df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 507M 0 507M 0% /lib/init/rw
udev 10M 48K 10M 1% /dev
tmpfs 507M 0 507M 0% /dev/shm
rootfs 7.4G 869M 6.2G 13% /
“/etc/mtab” is as following.
$ cat /etc/mtab
tmpfs /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
udev /dev tmpfs rw,mode=0755 0 0
tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0
rootfs / rootfs rw 0 0
I think OpenBlockS A series are easier to manage than OpenBlockS 600, because storage device of A series is visible.
