1.6.7 Drive Roaming Drive roaming occurs when the drives are changed to different ports on the same controller. When the drives are placed on different channels, the controller detects the RAID configuration from the configuration data on the drives. Configuration data is saved in both the NVRAM on the RAID controller and on the drives attached to the controller. This action maintains the integrity of the data on each drive, even if the drives have changed their physical device ID. NOTE If you move a drive that is being rebuilt, the rebuild operation restarts; it does not resume from the stopping point. Follow these steps to use the drive roaming feature: 1. Turn off the power to the server and all drives, enclosures, and system components. Disconnect the power cords from the system. 2. Open the host system by following the instructions in the host system technical documentation. 3. Move the drives to different positions on the backplane to change the targets. 4. Determine the SAS target requirements. 5. Perform a safety check. a. Make sure that the drives are inserted correctly. b. Close the cabinet of the host system. 6. Reconnect the power cords to the system. 7. Turn on the power to the system. The controller then detects the RAID configuration from the configuration data on the drives
Currently SW and HW license keys can be used to enable CacheCade. But in the near future HW keys will be the only option enable CacheCade. Information about the usage of SW keys can be found in
3. CacheCade 가상 디스크 특성 다음은 CacheCade 가상 디스크 특성입니다.
CacheCade 가상 디스크는 1GB의 NV(Non-Volatile) 캐시가 포함된 컨트롤러에서만 지원됩니다. CacheCade 가상 디스크는 SSD로만 생성할 수 있습니다. CacheCade 가상 디스크의 최대 결합 크기는 512GB입니다. SLN156366_en_US__1icon 참고: 여러 개의 CacheCade 가상 디스크가 생성될 수 있지만, 최대 크기까지 단일 캐시 풀로 작동하도록 결합됩니다. 보안 SED(Self-Encrypting Disk) 또는 SSD가 포함된 가상 디스크의 데이터는 CacheCade에 의해 캐싱되지 않습니다. CacheCade 가상 디스크는 64KB보다 작은 입력 읽기만 캐싱합니다. CacheCade 가상 디스크는 읽기 캐시 전용입니다. CacheCade 가상 디스크는 CacheCade를 지원하지 않는 컨트롤러에는 마이그레이션이 불가능합니다. CacheCade 드라이브를 가져오면 RAID 0 VD가 발생할 수 있습니다. 가져온 후에는 CacheCade VD를 재구성해야 합니다. CacheCade 가상 디스크는 운영 체제에 표시되지 않습니다. SLN156366_en_US__1icon 참고: 비보안 SED가 있는 VD의 데이터는 CacheCade를 사용하여 캐싱할 수 있습니다.
Dec 2016 in order to activate CacheCade, you need a hardware or software license, and an LSI approved SSD. CacheCade Pro 2.0 requires a hardware key only.
Question I have bought CacheCade Pro 2.0 license (AOC-CHCD-PRO2-ESW) and optain the activation key from LSI Advanced Software License Management Portal. When I install the activation key to AOC-SA2LP-H8iR card with 2.130.363-1846 firmware, I can successfully make CacheCade Volume of SSD and assign it to some RAID Volume of HDDs. But the cache policy is locked to Write Through. By document, CacheCade Pro 2.0 support Write Back cache policy as it enhancement from prior version. What can I do to solve this problem?
Answer Please recommend customer reentering the LSI activation key. The case here is caused of customer was doing activating the license on old firmware previously and then upgrading the firmware without reentering the activation key because they saw there was "CacheCade" on the MegaRAID Advanced Software screen. It seem that the old firmware threat the CacheCade Pro 2.0 license to CacheCade 1.0 and the new firmware still do the same without reentering the same activation key as the attachment.
Question We have your RAID card below: Supermicro Raid Card: AOC-SAS2LP-H8IR (SMC2108) Also LSI hardware key: LSI Cachecade Physical Key: LSI00292 Will the LSI physical cachecade key work on the Supermicro AOC-SAS2LP-H8IR?
Answer No, it would not. We only support software license, part no is AOC-CHCD-PRO2-ESW.(Note: The license key sold before, AOC-SAS2-CHCD-ESW, was no longer available.)
그리고 offline 했다가 online 하니 Media Error Count가 0으로 리셋되던데 원래 의도된 작동인 듯

The CacheCade 2.0 is now supported. Please make sure to use the firmware of version 2.120.53-1235 or later. Older firmware does not support the CacheCade. For the latest firmware, please go to:https://www.supermicro.com/wdl/driver/SAS/LSI/2108/Firmware/.
It also require to purchase CacheCade lincense, AOC-CHCD-PRO2-ESW. Date Posted 02/18/11
