In addition to the regulars (House Finch, Blue Jay, and Northern Cardinal) at my bird feeder this morning, a Goldfinch with it winter colors stopped by. All of the bird left when one of the neighborhood cats showed up.

While on a walkabout in Bergen near the Kunstmuseum, I noticed a large crow like bird with a white underbelly. Later identified as an Eurasian Magpie. These are believed to be one of the most intelligent of non-human animals.

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.

In addition to the regulars (Dark-eyed Junco, Mourning Dove, Blue Jay, and Northern Cardinal) at my bird feeder this morning, a flock of aggressive European Starlings arrived. They left when some American Black Crows landed in my backyard.
