結局、一長一短なのだが、まだしばらくはproxmoxには移行できそうにない。

In the end, both have their pros and cons, but it seems I won’t be able to switch to Proxmox for a while yet.

だが、運用面では、proxmoxでiSCSIをshared storageにしてる時、vmのsnapshotやcloneに対応していなかったり、iSCSIのlun対応が不十分であったりと言うあたりがどうしても困る。

However, from an operational standpoint, Proxmox presents unavoidable issues when using iSCSI as shared storage: you can’t take snapshots, clone VMs, or rely on sufficient iSCSI LUN support

実際若干遅いし、機能面でもgpuのsr-iovやその機能を利用しているvmのmigrationなど、proxmoxが優れている点も多くある

In fact, it is somewhat slow, and there are many aspects where Proxmox is superior in terms of features as well, such as GPU SR-IOV and the migration of VMs utilizing that functionality.

xcp-ngは、正直に言って、実装は古いし、xoも含め管理ツールはいまいちで、vmwareやproxmoxより良いとは思えない。

To be honest, the implementation of XCP-ng is outdated, and the management tools, including XO, are not very impressive, so I can't say it's better than VMware or Proxmox.

xcp-ngに満足しているわけではない。だが、shared storage(特にiscsiなど)の取り扱いや、vmの取り扱いに関しては、明確にproxmoxが劣る(但しcephはのぞく)

I am not fully satisfied with XCP-ng. However, when it comes to handling shared storage (especially iSCSI) and managing VMs, Proxmox is clearly inferior—except for Ceph.

この種の、サービス停止に気を使わなければならないシステムの冗長化は、本当に難しい。

It is really difficult to make this type of system redundant, where you have to be careful about service outages.

障害はまだ問題は小さい。むしろOSやDB Engineのupdateの方が難しい。連続で再起動するから頻繁にfailbackが発生する。

Failure is still a small problem.Rather, OS and DB Engine updates are more difficult.Failbacks occur frequently because of continuous reboots.

起こりうるシナリオを考えて、順序と設定を考える必要がある。

We need to think about possible scenarios and consider the sequence and setting.

問題は、carpの代表アドレスをPgPool-IIやPostgreSQLのMasterが変わった時にちゃんと追従させることや、切り替え中のサービス停止時間、sprit brainを起こさないようにすること。

The problem is to make sure that the deginated address of CARP follows properly when PgPool-II or PostgreSQL's Master changes, and to avoid service downtime or SPRIT BRAIN during the switchover.

そう言うことを考えると、何にしても情報を発信すると云うのは難しいことだ。

In this context, it is difficult to transmit information in any way.

そして、スマホでも配信可能。すごい進歩だ。
ただ、魅力ある良いコンテンツにしようとするなら、素材だけではダメで編集(多くの場合、演出も)が必要。

And it can now be delivered on a smartphone.I think this is a great progress.
However, if you want to make attractive content, it is not enough to just use the material, you need to edit (and in many cases, direct) it as well.

miniPCとmobile monitor、マイク付きのカメラ(場合によってはスマホ)、そしてmobile routerがあれば、簡単に配信できる。

With a miniPC, a mobile monitor, a camera with a microphone (and possibly a smartphone), and a mobile router, it is easy to distribute.
