适用场景

  • E系列(EF300/EF600/E2800)
  • SANtricity 11.70或更高版本

问题解答

磁盘驱动器
  • SAS驱动器:大小可以是512字节或4 KB,具体取决于磁盘型号

示例 (Storage Array Profile log):

Media type: Hard Disk Drive Interface type: SAS Speed: 10,500 RPM Current data rate: 12 Gbps Logical sector size: 512 bytes Physical sector size: 512 bytes Product ID: ST1200MM0009 Drive Firmware: MS02 Serial number: WFK88RB90000K101ALHL Manufacturer: SEAGATE Date of manufacture: July 21, 2020
Media type: Hard Disk Drive Interface type: SAS Speed: 10,500 RPM Current data rate: 12 Gbps Logical sector size: 512 bytes Physical sector size: 4096 bytes Product ID: ST1800MM0129 Drive Firmware: NE03
  • 固态磁盘(SSD)
    • SAS类型:4 KB
    • NVMe类型:4 KB
示例: 
Drive media type:       Solid State Disk
Drive interface type:     NVMe
Physical block size:      4,096 bytes
Logical sector size:      512 bytes
Shelf loss protection:     No
 
  Media type:           Solid State Disk   
   Interface type:         SAS         
    Drive path redundancy:      OK           
      
    Current data rate:        12 Gbps        
    Logical sector size:       512 bytes       
   Physical sector size:      4096 bytes   
 
  • 默认情况下:
    • 采用FC类型的EF300和EF600为4K
    • 采用iSCSI类型的EF300和EF600为512字节
    • E2800为512字节
  • 512字节和4 KB均受支持、并可通过 命令行界面进行配置
  • 只有采用FC型号的EF300和EF600才能  [1]  在 创建卷时使用GUI功能配置卷块大小。
