## 摘要

- **SUSE Virtualization 两节点+仲裁（TNA）**：SUSE + Portworx(Everpure) + Supermicro；仲裁不存业务数据；**厂商称**单节点宕机约 **2 分钟**内 VM 迁回，级联双故障场景观测 I/O 中断约 **8 秒**；每站点存储基建成本可砍 **25–35%**（**厂商自称**）。
- **深信服 aSAN** 降级盘软隔离：13s 识别、分片级隔离、短暂故障可恢复副本（见 storage 日跟踪）。
- **Proxmox 24/7** 从 2026-10-19 覆盖 VE/PBS/PDM——可靠性卖的是工程师值班。
- **备份侧**：CrowdStrike 触发 Commvault Cleanroom / Rubrik 身份恢复；Cohesity Clean Room×HCLTech——可靠性边界扩到「可验证恢复」。

> … Two-Node with Arbiter (TNA) topology. … The arbiter doesn’t store any workload data. … swapping a heavy NVMe storage server for a lightweight witness can slash per-site storage infrastructure costs by 25 to 35 percent.
> … all virtual machines were back up and running on the surviving node within about two minutes. … Total observed I/O interruption … mere eight seconds.

### Proxmox 24/7
