Wherever possible, commands are labeled to indicate when they are supported for only a subset of controllers. For example, commands that apply only to 3ware 9000 series controllers are labeled as such and are not supported for 3ware 7000/8000 controllers. Within the 9000 series, some commands apply to only to models 9550SX, 9590SE, and 9650SE and not to 9500S, and are so labeled. A few commands apply only to models 9500S, and are labeled as such.Important!For all of the functions of the 3ware CLI to work properly, you must have the proper CLI, firmware, and driver versions installed. Check for the latest versions and upgrade instructions.This chapter includes the following sections:. “Features of the CLI” on page 2.
“Installing the 3ware CLI” on page 4. “Working with 3ware CLI” on page 6. “Understanding RAID Levels and Concepts” on page 9 Features of the CLI3ware CLI is a command line interface for managing 3ware RAID Controllers. It provides controller, logical unit, drive, enclosure, and BBU (Battery Backup Unit) management. It can be used in both interactive and batch mode, providing higher level API (application programming interface) functionalities.
Supported Operating SystemsYou can use the CLI to view unit status and version information and perform maintenance functions such as adding or removing drives. 3ware CLI also includes advanced features for creating and deleting RAID units online.For a summary of what you can do using the CLI, see “Common Tasks Mapped to CLI Commands” on page 19.Supported Operating SystemsThe 3ware CLI is supported under the following operating systems:.
Windows®. Windows 2000, Windows XP, and Windows Server 2003, both 32-bitand 64-bit. Linux®. Redhat, SuSE, both 32-bitand 64-bit. FreeBSD®, both 32-bitand 64-bit.For specific versions of Linux and FreeBSD that are supported for the 3wareCLI, see the Release Notes. TerminologyThis document uses the following terminology:Logical Units. Usually shortened to “units.” These are block devices presented to the operating system.
A logical unit can be a one-tier, two-tier,or three-tierarrangement. JBOD, Spare, and Single logical units are examples of one-tierunits. RAID 1 and RAID 5 are examples of two-tierunits and as such will have sub-units.RAID 10 and RAID 50 are examples of three-tierunits and as such will have sub-sub-units.Port. A controller has one or many ports (typically 4, 8, 12, 16).
Each port can be attached to a single disk drive. On a controller such as the 9590SE-4ME,with a multilane serial port connector, one connector supports four ports.For additional information about 3ware controller concepts and terminology, see the user guide that came with your 3ware RAID controller or the user guide portions of the 3ware HTML Bookshelf. Introduction to the 3ware Command Line Interface Installing the 3ware CLIWarning!If you are using 3DM, as opposed to 3DM2, AMCC does not recommend installing both 3DM and CLI on the same system. Conflicts may occur. For example, if both are installed, alarms will be captured only by 3DM.
You should use either CLI or 3DM to manage your 3ware RAID controllers.This is not an issue for 3DM2. It can be installed with CLI.(3DM was an earlier version of the software, which worked with 7/8000 model 3ware controllers.
3DM 2 works with the 9000-series.) Installing the 3ware CLI on Windows3ware CLI can be installed or run directly from the 3ware software CD, or the latest version can be downloaded from the 3ware web site,. Online manual pages are also available in nroff and html formats. These are located in /packages/cli/twcli.8.html or twcli.8.nroff.To install 3ware CLI on Windows. Copy the file twcli.exe to the directory from which you want to run the program.CLI is located on the 3ware CD in the directory packagescliwindowsNote: CLI comes in both 32-bitand 64-bitversions. Be sure to copy the correct version for the version of the operating system you are using. Permissions Required to Run CLITo run CLI, you can be logged onto Windows with one of the following sets of permissions:. Administrator.
![]()
User with administrator rights. Domain administrator. Domain user with Domain Admin or Administrator membershipWithout the correct privileges, CLI will prompt and then exit when the application is executed.

Microsoft Ultimate SP1. Microsoft. CanocialREAL TIME PRICINGPage 4. AMCC Storage 3ware 9690SA SAS/SATA RAID Controller Test ResultsOne of the most important aspects of a RAID controller, with regard to performance, is the ability to perform very fast read and write operations on a variety of block sizes. Since this controller features an onboard cache, it will be interesting to see how the read and write speeds vary depending on the size of the block of data. For sequential read and write operations, blocks that are smaller than the controller cache size will be written faster than they are read.
Overall, both sequential read and sequential write speeds should decline slightly as the block sizes get larger, because of the increased IO overhead which is mitigated in part by the efficiency of the cache mechanism. Random reads and writes defeat the cache mechanism by requesting data from a variety of positions all over the drive. In this case, both read and write speeds will be slower than sequential because of the inability of the cache to speed up operations. Of course, the performance characteristics of the controller are determined by the speed and performance of the drives in the array.
![]()
The drives that I am using are some of the fastest on the market, so drive performance will not be as much of an issue in this case.Enough theory from me, lets get to the benchmarks!Blocksize 50MB Windows Vista Ultimate Service Pack 1Windows Server 2008The first thing that I noticed when I ran this benchmark was the sheer speed with which this controller card handled sequential reads and writes to the array. The fastest SATA drives can push data is 150MB/second. This array is pushing at least double that. As for reads, there is an 80% speed increase over SATA.
The random reads and writes were quite fast as well. While those numbers at the bottom of the benchmark may look very small, those are actually extremely small block size random reads, which effectively bypasses the disc and controller cache.Blocksize 100MB Windows Vista Ultimate Service Pack 1Windows Server 2008As I predicted, the read speeds are beginning to decrease, as the amount of time spent aligning disc spindles increases; the true power of this RAID card comes into play on the writes, which actually increase in speed. That is the power of a RAID card with onboard cache RAM; regardless of the blocksize, write performance stays pretty constantBlocksize 500MB Windows Vista Ultimate Service Pack 1Windows Server 2008Again, the read speeds are decreasing while the write speeds still increase. This increase is due, in part, to the fact that it the nature of a write operation means that placement on the array does not matter; the controller does not have to wait on the discs to sync up. The nature of read operations depend heavily on the location of the files on the array, so the average read operation may be spread over only one or two disks at a time, limiting transfer speed.Blocksize 1000MB Windows Vista Ultimate Service Pack 1Windows Server 2008And finally, just for fun, I cranked this beast up the the largest block size just to see what would happen. Random reads and writes are still declining, but sequential behaves as expected: that is lightning fast!REAL TIME PRICINGPage 5.
AMCC Storage 3ware 9690SA SAS/SATA RAID Controller Test Results (continued)These graphs are a little tougher to read and understand, but I'll do my best to interpret them for you. What these surfaces represent is the performance parameters of the controller card under a variety of IO situations.
Higher values are better here. In the read performance test, we will see how quickly the controller card can get data from the disk to the bus. On average, the read speed was approximately 1.2GB/s; those numbers are stunning! Mind you, most of the file sizes tested were well within the size of the cache of the controller card and thus this does not take into account the actual disk access times. Server 2008 dominates in this series of tests, as a true server platform should.IoZone 3 Write Test Windows Vista Ultimate Service Pack 1Windows Server 2008In the Write test, the average write speed is just over 683MB/s. Once again, the performance of this card is blowing me away.IoZone 3 Random Read Test Windows Vista Ultimate Service Pack 1Windows Server 2008The random read test attempts to defeat the cache by reading from locations all over the drive.
The performance that these graphs show is just phenomenal! The average random read speed is 1.0GB/s!IoZone 3 Random Write Test Windows Vista Ultimate Service Pack 1Windows Server 2008The random write test attempts to defeat the cache by reading from locations all over the drive. As is typical of this test suite, the writes are slower than the reads, the average being about 650MB/s. One interesting thing to note is that larger writes perform better. A good rule to remember!REAL TIME PRICINGPage 6. AMCC Storage 3ware 9690SA SAS/SATA RAID Controller Linux Test ResultsFor the sake of completion, I tested Ubuntu Server LTS briefly. I found that the Linux 2.6 kernel already had full driver support for the card which was really nice.
Here is the rundown from the IO Zone benchmarks that I ran. As before, higher is better. Areas that are completely flat and on the bottom were not tested.
Ubuntu Server LTSFrom these tests, we can see that the performance of this controller card on Ubuntu Server LTS is extremely good. Not only are the transfer rates faster than those of either Windows Vista or Windows Server 2008, the surfaces are flater which means that performance will be consistant. IO Zone is the only benchmark that I know of that would run on both Windows and Linux, and these results are posted for general performance comparison only.Further Tests DataMarck 0.04 Test Windows Vista Ultimate Service Pack 1Windows Server 2008Datamarck is a good benchmark tool that gives us a general idea of how fast the RAID array is over its entire length. It measures two variables, response time in milliseconds and bandwidth in megabytes per second. Lower response times mean that the disk will perform better for all types of access, so lower is better. More bandwidth means that more data can be transfered to the disk in the same amount of time, so higher is better. As we can see from these benchmarks, Windows Server 2008 has a clear edge on Windows Vista.
While the latency is very low, Windows Server 2008 dominates the bandwidth test.HD Tune Windows Vista Ultimate Service Pack 1Windows Server 2008HD Tune is a benchmark that, much like Datamarck, shows the performance of the array over its entire length. This gives us an idea of how well the controller card is managing read and write data caches as well as how fast the disks are. As before, higher bandwidth is better, and lower access times are better.
One addition to this test is the burst rate, the burst rate is the fastest sustained rate of data transfer that can be expected. This is calculated based on the performance data from the entire test. Notice that while the burst rate is the same, Windows Server 2008 again smashes Vista in the bandwidth category. With an average access time of just over 5.8 ms, latency is not a factor in either of these benchmarks.REAL TIME PRICINGPage 7. AMCC Storage 3ware 9690SA SAS/SATA RAID Controller ResultsSo lets recap. My experience with this card has been wonderful.
At the beginning, when I was installing the Operating Systems, I found that for the Microsoft Products I was required to insert the product cd to obtain drivers for the hardware. Ubuntu featured native driver support which was a very nice feature. From the test results, this card can be expected to perform quite well under the stress of an average server. The high efficiency cache and low write latency makes this card suitable for data center and or webserver usage.Overall, Windows Server 2008 featured higher bandwidth than Windows Vista. On the IO Zone tests, Linux was hands down the winner, but without other benchmarks to completely test this; I can still say that the performance I witnessed during the install and testing process was excellent. The commandline RAID interface is very standard, which is good if you are considering purchasing this product as it will be very similar, in this respect, to other cards on the market. Overall, I was extremely impressed.ConclusionsIn my experience, gear has always been top notch and the Storage is no exception.
The the AMCC 9690SA provides consistent, quick performance and excellent reliability. This consistency implies that the AMCC 9690SA is well suited to a variety of roles in any server. From my experience of working with and testing this card, I am happy to say that it will make a nice addition to my own growing server farm. At an average selling price of about, somewhat cheaper than the competitors' cards, I would reccomend that anyone looking to put together a server farm give this card serious consideration.REAL TIME PRICINGCopyright © 2005 Techware Labs, LLCAll Rights Reserved.
