第 7 章 QAT 加速进行加密和压缩

Intel QAT (QuickAssist Technology)可以通过将实际加密和压缩请求卸载到硬件 QuickAssist 加速器来提供扩展的加密和压缩服务，这比那些特定计算密集型工作负载的通用 CPU 更加高效。

重要

QAT 只能在 Red Hat Ceph Storage 7.1 中的新设置上配置（仅限Greenfield）。QAT Ceph 对象网关守护进程不能与非 QAT （常规）Ceph 对象网关守护进程配置在同一集群中。

重要

Ceph 对象网关中的硬件加速压缩需要使用 QAT 设备的 Sapphire 或 Emerald Rapids Xeon CPU （或更新版本）上的 RHEL 9.4。如需更多信息，请参阅 Intel Ark。

先决条件

一个正在运行的 Red Hat Ceph Storage 集群。
已安装 Ceph 对象网关。

'GRUB' 配置为传递 intel_iommu 参数。

grubby --update-kernel=ALL --args="intel_iommu=on"

7.1. 设置 QAT 服务

您可以设置 QAT 服务来加密和解密 Ceph 对象网关对象。

流程

安装 qatlib-service、qatlib、qatzip 和 qatengine 软件包。
```
# dnf install -y qatlib-service qatlib qatzip qatengine
```
将 'root' 添加到 HOST 上的"QAT"组中。
```
# usermod -aG qat root
```
确保 limits.conf 文件存在以下数据。
1. 要执行数据加密，请确保在配置文件中将 ServicesEnabled 设置为 sym。
```
# cat /etc/sysconfig/qat

ServicesEnabled=asym
POLICY=8
```
2. 要执行数据压缩，请确保在配置文件中将 ServicesEnabled 设置为 dc。
```
# cat /etc/sysconfig/qat

ServicesEnabled=dc
POLICY=8
```
3. 要执行数据加密和压缩，请确保在配置文件中将 ServicesEnabled 设置为 sym,dc。
```
# cat /etc/sysconfig/qat

ServicesEnabled=asym,dc
POLICY=8
```

使用以下数据配置 limits.conf 文件。

# sudo vim /etc/security/limits.conf

...
root - memlock 500000
ceph - memlock 500000
...

在 limits.conf 文件中启用配置。
```
# sudo su -l $USER
```
启用 QAT 服务。
```
# systemctl enable qat
```
重新引导节点。
```
# systemctl reboot
```

创建规格文件，并将额外的参数传递给 podman 用于 Ceph 对象网关：

注意

您可以使用以下命令生成设备列表：

--device /dev/vfio --device /dev/qat_adf_ctl $（for i in ls /dev/vfio" | grep 'dev' | grep -v ':' ; do echo --device $i;
