7장. 암호화 및 압축을 위한 QAT 가속

PDF

Intel QAT(QuickAssist Technology)는 실제 암호화 및 압축 요청을 하드웨어 QuickAssist 가속기에 오프로드하여 확장된 가속화 암호화 및 압축 서비스를 제공할 수 있으며, 이는 이러한 특정 컴퓨팅 집약적 워크로드의 일반 용도 CPU보다 비용 및 전력 측면에서 더 효율적입니다.

중요

QAT는 Red Hat Ceph Storage 7.1(Greenfield 전용)의 새로운 설정에서만 구성할 수 있습니다. QAT Ceph Object Gateway 데몬은 비QAT(일반) Ceph Object Gateway 데몬과 동일한 클러스터에서 구성할 수 없습니다.

중요

Ceph Object Gateway의 하드웨어 가속 압축에는 QAT 장치가 있는 Sapphire 또는 Emerald Rapids Xeon CPU (또는 최신)에 RHEL 9.4가 필요합니다. 자세한 내용은 Intel Ark 를 참조하십시오.

사전 요구 사항

실행 중인 Red Hat Ceph Storage 클러스터.
Ceph Object 게이트웨이가 설치되어 있어야 합니다.
'GRUB'는 intel_iommu 매개변수를 전달하도록 구성되어 있습니다.
```
grubby --update-kernel=ALL --args="intel_iommu=on"
```

7.1. QAT 서비스 설정

Ceph Object Gateway 오브젝트를 암호화하고 압축하도록 QAT 서비스를 설정할 수 있습니다.

프로세스

qatlib-service,qatlib,qatzip 및 qatengine 패키지를 설치합니다.
```
# dnf install -y qatlib-service qatlib qatzip qatengine
```
HOST의 'QAT' 그룹에 'root'를 추가합니다.
```
# usermod -aG qat root
```
QAT 서비스를 활성화합니다.
```
# systemctl enable qat
```
노드를 재부팅합니다.
```
# systemctl reboot
```

사양 파일을 생성하고 Ceph Object Gateway의 podman에 추가 인수를 전달합니다.

참고

다음 명령을 사용하여 장치 목록을 생성할 수 있습니다.

--device /dev/vfio --device /dev/qat_adf_ctl $(i in ls /dev/vfio/*) | grep 'dev' | grep -v ':' ; echo --device $i;
