Continuing my adventures with micro servers I started using the ODROID-U3 from HardKernel.
I purchased these units from CorpShadow.
This board is about the size of a credit card, but one inch thick.
It uses a Samsung Exynos quad core processor with 2GB RAM.
The preloaded eMMC cards ship with Ubuntu 126.96.36.199 LTS.
The power supply is 5V@2A (roughly 10 watts max).
At the office I have a couple 1U servers running VMware ESXi that host DNS and inbound email gateways. These ODROID-U3’s would be perfect replacements. I can drop in four of each and still have lower power consumption and heat generation while also expanding the redundancy.
I am preparing a repository for the compiled packages I have made for updated software since the bundled packages are outdated.
I have packages for:
- Firebird 2.1.7
- Postfix 2.11.5
- ldb 1.1.20 (ldb-tools, libldb1, python-ldb)
- ntdb 1.0-7 (libntdb1, ntdb-tools, python-ntdb)
- talloc 2.1.2 (libtalloc2, python-talloc)
- tdb 1.3.5 (libtdb1, python-tdb, tdb-tools)
- tevent 0.9.24 (libtevent0)
I am working on packages for:
- Samba 4.1.17, 4.1.18, 4.2.1
Other packages I am considering:
- OpenLDAP: 2.4.31 available, 2.4.40 latest
I am targeting the following services for using an ODROID-U3 micro server:
- Public DNS
- Private DNS/DHCP
- Inbound email gateway
- LDAP “slaves”
- Private NTP
- Private Blacklist (for email and firewall)
One thing I really like about these machines: less than 30 seconds from power on to full availability.
This sure makes a reboot during business hours a lot less of a hassle.
