1. Software & Firmware Versions
1.1 Supported Controllers
The Firmware and Software listed in the next section will support only the following Adaptec RAID controllers:
o ASR 5405
o ASR 5085
o ASR 5805
o ASR 5445
o ASR 51245
o ASR 51645
o ASR 52445
Note: For this beta it is recommended to use a Series-5 card with 512MB Dram Cache (all but 5405)
1.2 Software Version:
o FW version : 5.2.0 - B16910
o Windows Drivers : 5.2.0 - B16907
o Linux Drivers : 1.1.5 - 2467
o Adaptec Storage Mgr : 6.10 - B15530
1.3 Supported Operating Systems:
• Windows 2003 Server, Enterprise, Standard (32-bit, 64-bit)
• Windows 2008 Server, Enterprise, Standard (32-bit, 64-bit)
• Windows XP All versions
• Windows Vista All versions
• Linux - RHEL 5.x, SuSE 10.x, Kernels 2.6.x
1.4 Supported SSDs:
o Adaptec Intel SLC SSD X-25E (comes with the demo package). Note that at this stage no other SSDs are supported for ITP other than the one that is shipped with the beta package
2. Installation and Setup
2.1 Installation Instructions
The Adaptec SAS RAID Controllers Installation and User's Guide contains complete installation information for the controllers and drivers, as well as complete instructions for all utilities. The Adaptec Storage Manager User's Guide contains complete installation information for the Adaptec Storage Manager software.
2.2 Intelligent Tiered Provisioning Setup
Once the controller firmware is updated to the firmware version
listed in the section 1.2, please follow the instructions for
setting up the Intelligent Tiered Provisioning (ITP) feature.
* The ITP feature can be now enabled or disabled from the Adaptec
Storage Manager software and from the BIOS Ctrl-A Utility.
* Enable the Read and Write array caches during the array creation
Installation Steps:
• Install Controller Firmware, device drivers and Adaptec Storage Manager as outlined in the user manual. Use the drivers, ASM and firmware files that are shipped with the ITP beta package
• Shut down the system and attach the SSD drive provided by Adaptec to the controller (note that the SSD can be plugged to one of the regular SATA/SAS ports of the controller. It can also be inserted into an appropriate 2.5” drive carrier and/or into an appropriate backplane for SFF drive if available. Also connect the HDD drives you want to use for testing
• Start Adaptec Storage manager and Initialize the SSD (right click on SSD in ASM and choose initialize
• Right click on SSD and choose “Add to ITP Pool”. This step makes the SSD a part of the ITP caching pool (without this step, the SSD might be used as a storage device like any HDD)
• Create your HDD RAID arrays
• Right click on the RAID array and choose “Configure ITP” then “Enable ITP” to enable SSD Caching (ITP) for any available RAID Storage Array
3. General Cautions
• The firmware will expire in 60 days, so it is suggested not to use this code in a production environment.
• Use only the drives that are provided by Adaptec. The Intel X25E drives obtained from other vendors will not be available for the ITP pool.
• The code you are receiving is going through a development cycle and is given to you "as-is" basis. It has not gone through any formal test cycle and it is given to you for evaluation purposes only. So please do not deploy the code in a production environment.
• The maximum number of SSDs supported in the ITP feature is set to 4.
• The cache needs to be full in order to provide optimum performance. The cache fill logic in the firmware is adaptive and will take Some time to fill up the cache depending on the work load (could be minutes to several hours).
• Always perform a clean shutdown, ie, properly shutting down the OS instead of a pressing the reboot button or pulling the power. If the system is not properly shutdown, the cache data gets invalid and the firmware starts filling up the cache again. This results in temporary loss of the performance boost until the cache is rebuilt.
4. Latest improvements
• Automatic statistics printouts every 10 minutes to log To transport ITP-related statistics during in-field beta tests, ITP does periodical statistics printouts to UART every 10 minutes (equal to UART "rrcstats", no counter reset).
• At the end of the log, the phonehome data and "getstats" printouts are included. This data can be collected and transported back to us through the support.zip functionality. Beta test customers should be asked to return a support.zip that was created after an ITP test, before a reboot, as part of their feedback. This data will give us an idea of the IO load and ITP efficiency in a customer's application.
• Automatic ITP cache fill, if the ITP container space ................
