Passive Computer Processor Cooler: Synology DS3617xs.

Four years ago I posted an image of the large passive cooler in a Synology DS-3615xs NAS (network attached storage) system. 08-December-2015 The time has come where I need to increase my data storage capacity, but at the same time want to decrease the amount of energy required to maintain the storage. I’ve opted to upgrade to the Synology DS-3617xs NAS with 16TB Seagate EXOS hard drives. Once I get the data transferred, I will be able to retire two DS-3615xs NAS systems and four DX-1215 expansion systems. This should reduce my daily electric energy consumption for the servers from ~24 kWh/day to ~7 kWh/day (corresponding to ~ $1,000/year). I will be able to monitor and confirm this using my Sense home energy monitor.

The Synology DS-3617xs came with 16GB of installed RAM. In order to create a single volume > 100 TB I needed to add additional memory. Installation of additional memory is now accomplished from the side of the DS-3617xs, which is a lot easier. I also installed a dual 10GB RJ-45 network card to be used for the heartbeat connection for running two of the DS-3617xs NAS systems in the High-Availability server mode. With the DS-3617xs you do not need to remove the difficult to disconnect power supply cables to access the interior of the server. The large passive processor cooler looks similar.

I am resisting NAS (Nikon Acquisition Syndrome) Today.

While reading the commentary on Thom Hogon’s site today, I saw that B&H (and other vendors) had received new Nikon 500 mm and 600 mm f/4 VRII Super Telephoto lenses and still have some available for sale. These have been in short supply for a long time, and may be in even shorter supply for an even longer time since the earthquake in Japan. I held out and did not place an order (and thus didn’t help the economy by spending nearly $20K). This was hard, since I missed many great photo opportunities while on the Semester at Sea, Spring Enrichment Voyage — Ultimate Travel Photography Workshop (UTPW-II) earlier this month. Several of the folks attending the workshop had the larger 500 mm and 600 mm lenses and were able to get some great images that made those of us with lighter kits (70-300 or 80-400) jealous.
