空きスロットの数に関して、ボックス内にあるRAMの量をサーバーを確認する方法はありますか(サーバーを開いて物理的に調べることなく)。また、私はそれがおそらくどれくらいのRAMを取ることができるかを知る必要がありますか?
/ proc/meminfoでRAMを確認できることは知っていますが、RAMの種類にどれだけ多くのスロットが空き/使用されているかについて、私は本当に心配しています。つまり、どのくらいのRAMを追加できるのか、特定のタイプにどのタイプを追加するのかを知る必要がありますが、その方法についてはわかりません。
(dmidecode
に加えて)Niceツールの1つはlshw
です。
例えば。、
$ Sudo lshw -short -C memory

別のオプションはlshw
コマンド(manページ)です-RAMスロットを含む多くのものに関する出力を提供します。完全な出力は非常に長くなりますが、Sudo lshw -short
は、スロットにRAMがあるかどうかに関係なく、RAMスロットごとに1行を含む要約を提供します。または、RAMに関する完全な情報を得るために、他のすべてを省略して、Sudo lshw -class memory
を実行できます。
Sudo lshw -short
から得られる出力は次のとおりです。
