Unity - 基本配置

 

创建pool

就是分配空间，

UnityVSA初始部署时，没有数据盘，无法创建pool，需要添加磁盘

 

 

 添加2块50GB的disk

 

开始配置pool

 

因为用的虚拟机，都是普通磁盘，所以 storage tier都选的 Performance tier；

如果是 Flash系列，就选Extreme Performance tier；

Extreme Performance tier： 

Storage tier

Drive types

Description

Default RAID configuration (physical deployments only)

Extreme Performance tier

Solid state extreme performance drives. The following types are supported:

• SAS Flash 2
• SAS Flash 3
• SAS Flash 4

Provides very fast access times for resources subject to variable workloads. For example, databases can achieve their best performance when using SAS Flash drives. SAS Flash drives are more expensive than SAS drives per GB of storage.

SAS Flash 2, SAS Flash 3, and SAS Flash 4 drives can be used together in the Extreme Performance tier. Only SAS Flash 2 drives can be used in the FAST Cache, and only SAS Flash 2 and SAS Flash 3 drives can be used in FAST VP.

RAID 5 (8 + 1).

Performance tier

SAS - Rotating performance drive

Provides high, all-around performance with consistent response times, high throughput, and good bandwidth at a mid-level price point. Performance tier storage is appropriate for database resources accessed centrally through a network.

RAID 5 (4 + 1).

Capacity tier

NL-SAS - Rotating capacity drive

Provides the highest storage capacity with generally lower performance. Capacity storage is appropriate for storing large amounts of data that is primarily static (such as video files, audio files, and images) for users and applications that do not have strict performance requirements.

NOTE: For data that changes or is accessed frequently, capacity tier storage has significantly lower performance.

RAID 6 (6 + 2).

 

 

 

真机上，这一步会要求选择raid；

  

 

 

 

 

 

 

 

 

 

 

pool配置完成；

 

配置LUN；

 

 

 

 

 

 

现在还没配置主机，所以没法映射，先跳过；

 

 

 

snapshot schedule

snapshot schedule能够将系统设置为定期拍摄存储资源中数据的快照。每个快照都带有创建日期和时间的时间戳，并包含自上次快照以来更改的存储资源中数据的时间点映像。以下默认快照计划可用：

 默认保护-每天03:00拍摄快照，快照保留2天。

保留时间更短的保护—每天03:00拍摄快照，快照保留1天。

具有更长保留时间的保护—每天03:00拍摄快照，快照保留7天。

虽然无法编辑默认快照计划，但可以通过选择希望系统拍摄快照的间隔、时间和天数，并指定希望保留快照的时间，来创建自定义计划。您还可以根据希望系统复制快照的频率控制复制快照首选项。
