*** AWS Route53 にレジストラを移行する検討を行ったが、結果的に VALUE DOMAIN の登録を延長 [#rf23eca6]
- AWS Route53 に移行した場合
-- .com ドメインの年間利用料金は $12.0
-- ドメイン移行（受け入れ）の料金が 別に $12.0 発生する
-- &ref(Amazon_Route_53_Domain_Registration_Pricing_20140731.pdf,center,AWS Route53 ドメイン料金表);

- [[VALUE DOMAIN:https://www.value-domain.com/]] 
-- user = kittyfred
-- pass = !frex7785VD (20200102 Update)

-- 更新費用は年額 1,430円［税込み］、AWS の料金と実質等価なので移行費用分だけ安くなる

-- 結論として、&color(red){5年（2026-5-16 まで）分 VALUE DOMAIN で延長}; した
-- &ref(HMUNA_DOMAIN.jpg);

*** HDD ベンチマークソフト（diskspd）の導入 [#a8471580]
- 導入準備（必要パッケージをインストールし、diskspd 自体はソースを導入してビルド）

-- ソースコードの入手
--- git clone https://github.com/microsoft/diskspd-for-linux.git
--- &ref(diskspd.tgz);

-- Ubuntu パッケージ（libaio, libaio-dev）の導入
--- sudo apt-get install libaio1
--- sudo apt-get install libaio-dev

-- diskspd のビルド
