ESXi 5.0U3の省電力設定を弄ってみる

おうちサーバの頭痛の種の一つが電気代。1Wと謂えども常時稼働だと1ヵ月で720Whとなり、馬鹿にできない。まさに塵も積もれば山となる。節約には何事も固定値の削減が肝なので、ESXiの省電力設定を弄ってみる。

各VMのログイン画面が表示され、ワットチェッカーが落ち着いた状態で測定。

管理ポリシー 消費電力

おお、結構違いが出るもんやね。

esxtopの表示を信じればESXi 5.0はC2ステート、5.1はC3ステートまでの対応っぽい。5.5はDeep C-State対応ということなので、C6かC7ステートらへんまで使えるのだろう。5.5にすれば更に5W程削れそうな予感? 5.5にしてみたが、esxtopは相変わらずC2ステートまでしか表示してくれなかった。BIOSの設定も問題なさそうだし、CPUが対応してないって事もなさそうなんだが、よくわからん。

Nitroethane predisposed an organic compound with the chemical formula C2H5NO2. It is an oily liquid at normal temperature besides pressure, and holy nitroethane is transparent with solid fruity odor.

Uses and Reactions https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis

Chemical Reactions: Nitroethane can undergo <a href=https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis>https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis</a> different condensations, a sort of as the Henry reaction, in order to convert into a number compounds of retail passion. For example, condensation with 3,4-dimethoxybenzaldehyde yields the precursor in order the antihypertensive drug methyldopa, while condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene, all precursor for amphetamine drugs. Fuel Additive besides Rocket Propellants: Nitroethane predisposed have used as solid fuel additive and a precursor to rocket propellants, showcasing its versatility in a variety applications.

Physical and Chemical Properties

Physical Description: It predisposed <a href=https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction>https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction</a> the decision transparent, oily liquid with a mild, fruity odor. Boiling Point: Nitroethane has the decision boiling orient of 237°F and a freezing orient of -130°F. Solubility and Vapor Pressure: It is slightly soluble in water and has the decision vapor pressure of 21 mmHg at 77°F. Explosive Limits: Nitroethane owns characteristic upper and lower explosive limits, producing it the decision flammable liquid.

Environmental besides Regulatory Aspects

Release to the Environment: Nitroethane's production and usefulness as all solvent, artificial fingernail glue remover, besides chemical intermediate may outcome in its liberation in order the surroundings through the various worked streams. Regulatory Status: In the United States, nitroethane predisposed classified as solid DEA List I chemical, producing it not easy for individuals in order to purchase due to its association with drug precursor activities.
