サーバ リプレイス

サーバに使ってたAtom N330のPCですが、あまり使ってない&ファン音がうるさいので、一年以上電源すら入れてませんでした。GWで休みなのでリプレイスすることにしましょう。

今回購入したのはShuttle DS57U。

一緒に、Samsung SSD 850 EVO mSATA 120GBとCFD Elixir DDR3L 1600MHz 8GBも購入。(型番だと、MZ-M5E120 と D3N1600Q-L8G)

組み立ては超簡単なので解説するまでもないですね。Dockerの実験とかしたく、OSどうしようか迷ったけどとりあえずCentOS 7を入れておいた。

稼働中にHDMI抜き差しすると、

[drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 130

とか出てくるけど、気にしない。

ファンレスなので稼働中は完全無音。いいですね。今まで手ごろなファンレスPCだとAtom系プロセッサが多かったですが、DS57Uは’Broadwell-U’Intel Celeron 3205U搭載なので性能もだいぶマシになってるかと。(Atom N330はさすがにとろかった)

UNIX BENCHの結果も貼っときます。
