本节讨论使用Amazon FSxN为适用于NetApp的向量数据库解决方案设置Milvus集群。

Milvus与Amazon FSxN for NetApp ONTAP—文件和对象双重性

在本节中、我们需要在云中部署向量数据库的原因以及在Docker容器中的Amazon FSxN for NetApp ONTAP中部署向量数据库(Milvus独立)的步骤。

在云中部署矢量数据库可提供多项显著优势、尤其是对于需要处理高维度数据和执行相似性搜索的应用程序。首先、基于云的部署提供可扩展性、支持轻松调整资源、以满足不断增长的数据量和查询负载的需求。这样可以确保数据库在保持高性能的同时高效地处理不断增长的需求。其次、云部署可提供高可用性和灾难恢复、因为可以在不同地理位置之间复制数据、从而最大限度地降低数据丢失的风险、并确保即使在意外事件发生时也能持续提供服务。第三、它不仅经济高效、因为您只需为所使用的资源付费、而且可以根据需要进行扩展或缩减、从而无需在前期投入大量硬件。最后、在云中部署矢量数据库可以增强协作、因为数据可以从任何位置访问和共享、从而促进基于团队的工作和数据驱动的决策。
请检查在此验证中使用的Milvus独立架构以及Amazon FSxN for NetApp ONTAP。

错误：缺少图形映像

  1. 创建适用于NetApp ONTAP的Amazon FSxN实例、并记下VPC、VPC安全组和子网的详细信息。创建EC2实例时需要此信息。有关详细信息、请单击此处- https://us-east-1.console.aws.amazon.com/fsx/home?region=us-east-1#file-system-create

  2. 创建EC2实例、确保VPC、安全组和子网与Amazon FSxN for NetApp ONTAP实例的VPC、安全组和子网匹配。

  3. 使用命令"apt-get install NFS-common"安装NFS-common、并使用"sudo apt-get update"更新软件包信息。

  4. 创建一个挂载文件夹、并在此文件夹上挂载Amazon FSxN for NetApp ONTAP。

    ubuntu@ip-172-31-29-98:~$ mkdir /home/ubuntu/milvusvectordb
ubuntu@ip-172-31-29-98:~$ sudo mount 172.31.255.228:/vol1 /home/ubuntu/milvusvectordb
ubuntu@ip-172-31-29-98:~$ df -h /home/ubuntu/milvusvectordb
Filesystem            Size  Used Avail Use% Mounted on
172.31.255.228:/vol1  973G  126G  848G  13% /home/ubuntu/milvusvectordb
ubuntu@ip-172-31-29-98:~$

  5. 使用"apt-get install"安装Docker和Docker准备。

  6. 基于Docker compose．yaml文件设置Milvus群集，该文件可从Milvus网站下载。

    root@ip-172-31-22-245:~# wget https://github.com/milvus-io/milvus/releases/download/v2.0.2/milvus-standalone-docker-compose.yml -O docker-compose.yml
--2024-04-01 14:52:23--  https://github.com/milvus-io/milvus/releases/download/v2.0.2/milvus-standalone-docker-compose.yml
<removed some output to save page space>

  7. 在Docker compose .yml文件的"volumes"部分中、将NetApp NFS挂载点映射到相应的Milvus容器路径、尤其是etd、minio和standalone.Check中的路径 "附录D：dkder-compose．yml" 有关yml更改的详细信息

  8. 验证已挂载的文件夹和文件。

    ubuntu@ip-172-31-29-98:~/milvusvectordb$ ls -ltrh /home/ubuntu/milvusvectordb
total 8.0K
-rw-r--r-- 1 root root 1.8K Apr  2 16:35 s3_access.py

ubuntu@ip-172-31-29-98:~/milvusvectordb$ cd
ubuntu@ip-172-31-29-98:~$ ls
docker-compose.yml  docker-compose.yml~  milvus.yaml  milvusvectordb  vectordbvol1
ubuntu@ip-172-31-29-98:~$

  9. 从包含docker-compose．yml文件的目录中运行docker-compose up -d。

  10. 检查Milvus容器的状态。

    ubuntu@ip-172-31-29-98:~$ sudo docker-compose ps
      Name                     Command                  State                                               Ports

ubuntu@ip-172-31-29-98:~$
ubuntu@ip-172-31-29-98:~$ ls -ltrh /home/ubuntu/milvusvectordb/volumes/

ubuntu@ip-172-31-29-98:~$

  11. 为了验证向量数据库及其数据在Amazon FSxN for NetApp ONTAP中的读写功能、我们使用了Python Milvus SDK和PyMilvus的示例程序。使用"apt-get install python3-NumPy python3-pip"安装必要的软件包、并使用"pip3 install pymilvus"安装PyMilvus。

  12. 验证向量数据库中Amazon FSxN for NetApp ONTAP的数据写入和读取操作。

  14. 如果客户希望通过S3协议访问(读取)在矢量数据库中测试的AI工作负载NFS数据、可以使用简单的Python程序进行验证。例如、本节开头的图片中提到的对其他应用程序中的图像进行相似性搜索。
