Dell PERC6 firmware maintenance release version 6.2.0-0013 Performance enhancements include significant improvements in random-write performance, multi-threaded write performance, and reduction in maximum and average I/O response times.
Microsoft Windows 32ビット形式のDell Update Package(DUP)は、Microsoft Windows 64ビットオペレーティングシステム上でも実行できるように設計されています。Microsoft Windows 64ビット形式のDell Update Package(DUP)は、Microsoft Windows 64ビットオペレーティングシステム上でのみ実行できます。デバイスドライバのアップデートを選択するときは、お使いのオペレーティングシステムに適したものを選択してください。
1. Enhanced disk IO performance in multiple SAS and SATA configurations.
2. Improved random IO performance.
3. Improved response and completion times for random IO.
4. Increased SATA disk command queue depth.
5. Improved disk medium error correction in certain scenarios.
6. Improved handling of faulty backplanes and enclosures.
7. Resolved an issue where a predicted failure was still being reported after that drive was replaced.
8. Corrected an issue where SATA disks in an MD1000 may become foreign after the server and enclosure are power-cycled.
9. Resolved an issue where the controller could not handle a large number of rebuilds under heavy IO stress.
10. Fixed an issue where Windows Server 2008 installation in uEFI mode fails when installing to a virtual disk larger than 2 terabytes.
11. Fixed an issue where some Intel platforms with a PERC 6 installed occasionally fail with Windows Hardware Malfunction blue screen error during OS reboots.
12. Made several cosmetic and usability enhancements to improved customer experience.
1. When viewing SATA physical disk properties from Ctrl-R or other management applications, the Vendor Identification will be translated as "ATA" followed by blanks.
2. If all physical disks making up a virtual disk are removed from the system or enclosure, the RAID controller will delete the virtual disk. If the disks are later re-inserted, they will be marked foreign and can be imported using a management application.
3. If a virtual disk is configured with write-back cache enabled and some or all of its physical disks are removed from the system or enclosure, the RAID controller will preserve the virtual disk's write cache. The controller will flush the preserved cache when the physical disks are replaced and the foreign configuration is imported. Any attempt to update controller firmware will be blocked when cache is preserved for a virtual disk.
4. Physical disks determined to contain a foreign configuration are not available for configuration as a new dedicated or global hot spare, or as a member of a new virtual disk. The foreign configuration must be imported or cleared from the physical disk before it may be used as a hot spare or member of a virtual disk. Physical disks with a foreign configuration will not appear on the Create New VD screen in Ctrl-R.
5. Prior to performing a virtual disk migration to another system, the source system must be powered off before removal of the physical disks to preserve the correct virtual disk state. This is not required for the target system and the physical disks may be inserted while the system is powered on or off.
6. The controller restricts the importing of virtual disks that are undergoing RAID Level Migration or Capacity Expansion. Do not interrupt virtual disks that are performing either of these operations because it will disable the ability to import the virtual disk and the data will be unavailable. Dell recommends that the user perform a data backup before starting these operations.
