弹性云服务器(Elastic Cloud Server, ECS)是一种可随时自助获取、可弹性伸缩的计算服务。它允许用户根据业务需求快速创建和管理虚拟机实例。硬盘是弹性云服务器的重要组成部分,用于存储数据。
一台弹性云服务器支持的硬盘数量取决于具体的云服务提供商和实例规格。一般来说,大多数云服务提供商允许每台服务器挂载多个硬盘,但具体数量会有所不同。通常,一台服务器可以挂载的硬盘数量在2到16块之间,具体取决于实例类型和配置。

以下是一个简单的示例代码,展示如何在腾讯云上创建一个带有两块数据盘的弹性云服务器:
import tencentcloud.common.credentials
import tencentcloud.common.profile
import tencentcloud.cvm.v20170312.cvm_client
# 设置凭证信息
cred = tencentcloud.common.credentials.Credentials("SecretId", "SecretKey")
clientProfile = tencentcloud.common.profile.ClientProfile()
clientProfile.httpProfile.endpoint = "cvm.tencentcloudapi.com"
# 创建客户端
client = tencentcloud.cvm.v20170312.cvm_client.CvmClient(cred, "ap-guangzhou", clientProfile)
# 创建实例请求
request = tencentcloud.cvm.v20170312.models.RunInstancesRequest()
request.ImageId = "img-xxxxxx"
request.InstanceType = "S2.SMALL1"
request.InstanceChargeType = "POSTPAID_BY_HOUR"
request.InstanceName = "TestInstance"
request.Placement = {"Zone": "ap-guangzhou-2"}
request.SystemDisk = {"DiskType": "CLOUD_PREMIUM", "DiskSize": 50}
request.VirtualPrivateCloud = {"VpcId": "vpc-xxxxxx", "SubnetId": "subnet-xxxxxx"}
# 添加数据盘
data_disk1 = {"DiskType": "CLOUD_PREMIUM", "DiskSize": 100}
data_disk2 = {"DiskType": "CLOUD_SSD", "DiskSize": 200}
request.DataDisks = [data_disk1, data_disk2]
# 发起请求
response = client.RunInstances(request)
print(response.to_json_string(indent=2))
