Lsi raid controllers

Lsi raid controllers DEFAULT
Below is a list of all known LSI SAS devices from the SAS1068 chipset to the very latest not yet publicly available SAS3xxx series.
Devices with links have been released and official website technical info/support.
Quite a few devices with no links are devices that may have been going to be released, are going to be released or just devices that never made it to production, but they are listed all the same.
I have where applicable written which devices are cross flashable to other devices of the same chipset.
If you have a controller and have successfully cross flashed or done something worthy, reply back here and the list will be updated.
If you find mistakes reply back.
If you know of other devices that we've missed reply back
If you find official webpages for devices listed but not linked reply back.

Key
4i = 1x internal 4 port SAS connector (SFF-8087)
8i = 2x internal 4 port SAS connectors (SFF-8087)
8e= 2x external 4 port SAS connector (SFF-8088)
24i4e = 6x internal 4 port SAS connector (SFF-8087) AND 1x external 4 port SAS connector (SFF-8088)
There are other combinations, but you get the idea :)
Some devices have SATA ports, ie a 4i device could mean 4x SATA connectors (these are rare)

Some devices have quite a few options when it comes to BBU's, these are optional extras, check website specs for options.

Some OEM devices look cheaper then their LSI counterparts (ie IBM ServeRAID M1015 vs LSI9240) this is due to the M1015 lacking RAID 5/50 and drive encryption.
IBM has a 'Advanced feature key' to enable the missing functions, these need to be purchased separately.
Be warned that the Software keys are NOT interchangeable between OEMs and LSI !!

Hope this is of use.

Disk array controller

A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It almost always implements hardwareRAID, thus it is sometimes referred to as RAID controller. It also often provides additional disk cache.

Disk array controller is often improperly shortened to disk controller. The two should not be confused as they provide very different functionality.

Front-end and back-end side[edit]

A disk array controller provides front-end interfaces and back-end interfaces.

  • Back-end interface communicates with controlled disks. Hence protocol is usually ATA (a.k.a. PATA), SATA, SCSI, FC or SAS.
  • Front-end interface communicates with a computer's host adapter (HBA, Host Bus Adapter) and uses:

A single controller may use different protocols for back-end and for front-end communication. Many enterprise controllers use FC on front-end and SATA on back-end.

Enterprise controllers[edit]

Main article: Disk array

In a modern enterprise architecture disk array controllers (sometimes also called storage processors, or SPs[1]) are parts of physically independent enclosures, such as disk arrays placed in a storage area network (SAN) or network-attached storage (NAS) servers.

Those external disk arrays are usually purchased as an integrated subsystem of RAID controllers, disk drives, power supplies, and management software. It is up to controllers to provide advanced functionality (various vendors name these differently):

  • Automatic failover to another controller (transparent to computers transmitting data)
  • Long-running operations performed without downtime
    • Forming a new RAID set
    • Reconstructing degraded RAID set (after a disk failure)
    • Adding a disk to online RAID set
    • Removing a disk from a RAID set (rare functionality)
    • Partitioning a RAID set to separate volumes/LUNs
  • Snapshots
  • Business continuance volumes (BCV)
  • Replication with a remote controller....

Simple controllers[edit]

A simple disk array controller may fit inside a computer, either as a PCIexpansion card or just built onto a motherboard. Such a controller usually provides host bus adapter (HBA) functionality itself to save physical space. Hence it is sometimes called a RAID adapter.

As of February  2007[update]Intel started integrating their own Matrix RAID controller in their more upmarket motherboards, giving control over 4 devices and an additional 2 SATA connectors, and totalling 6 SATA connections (3Gbit/s each). For backward compatibility one IDE connector able to connect 2 ATA devices (100 Mbit/s) is also present.

History[edit]

While hardware RAID controllers were available for a long time, they always required expensive SCSI hard drives and aimed at the server and high-end computing market. SCSI technology advantages include allowing up to 15 devices on one bus, independent data transfers, hot-swapping, much higher MTBF.

Around 1997, with the introduction of ATAPI-4 (and thus the Ultra-DMA-Mode 0, which enabled fast data-transfers with less CPU utilization) the first ATA RAID controllers were introduced as PCI expansion cards. Those RAID systems made their way to the consumer market, where the users wanted the fault-tolerance of RAID without investing in expensive SCSI drives.

ATA drives make it possible to build RAID systems at lower cost than with SCSI, but most ATA RAID controllers lack a dedicated buffer or high-performance XOR hardware for parity calculation. As a result, ATA RAID performs relatively poorly compared to most SCSI RAID controllers. Additionally, data safety suffers if there is no battery backup to finish writes interrupted by a power outage.

OS support[edit]

Because the hardware RAID controllers present assembled RAID volumes, operating systems aren't strictly required to implement the complete configuration and assembly for each controller. Very often only the basic features are implemented in the open-source software driver, with extended features being provided through binary blobs directly by the hardware manufacturer.

Normally, RAID controllers can be fully configured through card BIOS before an operating system is booted, and after the operating system is booted, proprietary configuration utilities are available from the manufacturer of each controller, because the exact feature set of each controller may be specific to each manufacturer and product. Unlike the network interface controllers for Ethernet, which can be usually be configured and serviced entirely through the common operating system paradigms like ifconfig in Unix, without a need for any third-party tools, each manufacturer of each RAID controller usually provides their own proprietary software tooling for each operating system that they deem to support, ensuring a vendor lock-in, and contributing to reliability issues.[2]

For example, in FreeBSD, in order to access the configuration of Adaptec RAID controllers, users are required to enable Linux compatibility layer, and use the Linux tooling from Adaptec,[3] potentially compromising the stability, reliability and security of their setup, especially when taking the long term view in mind.[2] However, this greatly depends on the controller, and whether appropriate hardware documentation is available in order to write a driver, and some controllers do have open-source versions of their configuration utilities, for example, and is available for FreeBSD since FreeBSD 8.0 (2009),[4][5] as well as / since 2015,[6] each supporting only their respective device drivers, this latter fact contributing to code bloat.

Some other operating systems have implemented their own generic frameworks for interfacing with any RAID controller, and provide tools for monitoring RAID volume status, as well as facilitation of drive identification through LED blinking, alarm management, hot spare disk designations and data scrubbing § RAID from within the operating system without having to reboot into card BIOS. For example, this was the approach taken by OpenBSD in 2005 with its bio(4)pseudo-device driver and the bioctl utility, which provide volume status, and allow LED/alarm/hotspare control, as well as the sensors (including the drive sensor) for health monitoring;[7] this approach has subsequently been adopted and extended by NetBSD in 2007 as well.[8]

With bioctl, the feature set is intentionally kept to a minimum, so that each controller can be supported by the tool in the same way; the initial configuration of the controller is meant to be performed through card BIOS,[7] but after the initial configuration, all day-to-day monitoring and repair should be possible with unified and generic tools, which is what bioctl is set to accomplish.

Setting Up Hardware RAID Volumes With LSI and Adaptec Host Bus Adapters

This chapter contains these topics:

RAID Options


Caution

Caution - Possible data loss: You must not insert a disk that has been previously configured with a RAID volume into a new RAID volume. Before permanently removing a disk that is part of an active RAID volume, use the appropriate RAID tool to delete the RAID volume from the disk.


The server modules that interoperate with the disk modules all have SAS host bus adapters that are capable of creating hardware RAID volumes.

The X6220 and T6300 server blades have an LSI 1068E SAS host bus adapter chip (with LSI firmware) on the blade’s motherboard.

Some server blades (see Supported RAID Controllers and Host Bus Adapters (HBA)) can use a RAID Expansion Module (REM) that uses the same LSI 1068E chip. This REM card is named the Sun Blade RAID 0/1 G2 Expansion Module.


Note - REMs are daughter cards that mount on the server blades.


Some server blades (see Supported RAID Controllers and Host Bus Adapters (HBA)) can use a REM card that uses Intel chips and Adaptec firmware. This REM card is named the Sun Blade RAID 5 Expansion Module.

All of these SAS host bus adapter options can control disks on the server blades (all the blades except X6450 can have on-board disks) and on the disk blade as well.

Both the LSI and the Adaptec controllers have two types of software for creating and managing RAID volumes. One type is a configuration utility that can be run from the BIOS before (or after) installation of an OS. The other type is a software application that runs on the server after an OS is installed.

RAID Software lists the various RAID possibilities.

  • The Adaptec BIOS Utility is documented in the Sun Intel Adaptec BIOS RAID Configuration Utility User’s Manual (820-4708).

  • The Adaptec RAID Manager, also known as the Sun StorageTek RAID Manager, is documented in the Sun StorageTek RAID Manager Software User’s Guide (820-1177).

Setting Up Hardware RAID With LSI Host Bus Adapters

Hardware RAID configurations can be set up with a server blade’s SAS host bus adapter. The type of controller varies from server module to server module (see Supported RAID Controllers and Host Bus Adapters (HBA)).

The X6220 and T6300 server modules that can be used with the Sun Blade 6000 Disk Module have an on-board LSI 1068E chip. Other server modules can use a RAID Expansion Modules (REM) that uses the same LSI 1068E chip.

The LSI 1068E SAS host bus adapter (an integrated RAID controller) simultaneously controls the disk drives on the server module itself (except for the X6450 servers that have no on-board disks) and the eight drives on the disk module, and can create RAID configurations involving all twelve disks. RAID 0 (striping), RAID 1 (mirroring), and RAID 1E (enhanced mirroring on three or more disks) are all supported by the firmware on the LSI 1068E chip.

Deciding Whether to Configure RAID Before or After OS Installation

You can configure hardware RAID either before or after loading the OS on your server module, with one exception: if you plan to create a RAID volume for your OS, the recommended procedure is to create the RAID first and then install the OS.

Configuring RAID for the Windows and Linux OS After the OS Is Installed

LSI has developed a software tool called the MegaRAID Storage Manager (MSM) for configuring and managing RAID on platforms running the Windows and Linux operating systems. Refer to Sun LSI 106x RAID User’s Guide (document number 820-4933) for a detailed description of MSM. You can download this document from:

http://docs.sun.com/app/docs/coll/blade6000dskmod

The MSM software is only available after the OS is installed.

Configuring RAID for the Solaris OS After the OS Is Installed

Solaris includes a RAID hardware utility, accessed with the command: . This utility is used for LSI controllers and has functionality that is similar to that of the LSI BIOS utility. is also covered in the Sun LSI 106x RAID User’s Guide (820-4933).


Note - The man page for states that the utility is for the LSI 1064 SAS host bus adapter, but it can also be used with the LSI 1068E controller.


To create a RAID volume where you can install your Solaris OS:

  1. Boot your server from a remote Solaris OS image.

  2. Use to create a mirror.

  3. Label the RAID volume.

  4. Power-cycle your server.

  5. Install the Solaris OS on your server.

The LSI RAID configuration utility that is entered from the server’s BIOS is valid for all x86 server blades and all supported operating systems.

  1. Power-cycle your server module.

    The BIOS screen appears.

  2. Watch for the LSI Logic Corp. screen which comes up soon after the opening screen.


    Figure showing LSI MPT BIOS screen.
  3. Press Ctrl-C to start the LSI Logic Configuration Utility.


    Figure showing LSI MPT BIOS screen.
  4. With the LSI 1068E adapter highlighted in the first screen, press Enter.

    The main screen of the utility opens


    Figure showing LSI configuration utility main screen.
  5. Use the arrow keys to select RAID Properties and press Enter.

    The next screen allows you to choose the type of RAID


    Figure showing RAID creation screen.
  6. Select the type of volume you want to create, in this case an IME volume.

    The next screen lists the disks you can choose to include in the volume and also disks you can choose as hot spares.


    Note - Despite the fact that there are dual paths to disks 1 - 7, they are not shown in the BIOS configuration utility. The utility hides them so that you cannot include the same disk twice in a volume. That is, you cannot mirror a disk with itself.



    Figure showing Create New Array screen.

    Note - Disks in the server blade are always listed first, followed by the disks in the disk blade. Here we see a single disk in the server blade (in bay 0) followed by eight disks in the disk blade (0 through 7).


  7. Use the arrow keys to highlight the [No] item in the RAID Disk column for the disks you want to include in the volume. For each such disk, press the spacebar or type the + or - key to change the [No] to [Yes].

  8. Use the arrow keys to highlight the [No] item in the Hot Spr column for the disks you want to use as hot spares. For each such disk, press the spacebar or type the + or - key to change the [No] to [Yes].

    Your selections might look like this:


    Figure showing disks selected for RAID volume.
  9. When you are satisfied with your choices, type to create the array.

    A confirmation screen appears.


    Figure showing Save Changes and Exit screen.
  10. Select Save changes then exit this menu, and then press Enter.

    The volume is created. When the utility finishes creating the volume, the main screen reappears.


    Figure showing LSI configuration utility main screen.
  11. Highlight RAID Properties and press Enter.

  12. When the next screen appears, select View Existing Array and press Enter.

    You see the volume you have created.

Setting Up Hardware RAID With the Adaptec Host Bus Adapters

This section describes how hardware RAID configurations can be set up with a server blade’s Adaptec SAS host bus adapter.

You can create up to 24 volumes (arrays) using either the HBA BIOS-based utility or the Sun StorageTek RAID Manager software. If a volume contains more than one disk, it is created as a RAID volume. You can also create a volume that contains only one disk. This is the mechanism you use to present a single disk to the OS.

Configuring Adaptec RAID After the OS Is Installed

The Sun StorageTek RAID Manager software is used for configuring and managing RAID on platforms running the Solaris, Linux, and Windows operating systems. Sun StorageTek RAID Manager Software and is documented in Sun StorageTek RAID Manager Software User’s Guide (820-1177). You can download this document from http://docs.sun.com.

The Sun StorageTek RAID Manager software is only available after the OS is installed.


Note - The Adaptec BIOS utility is not available for SPARC systems so you must use the StorageTek RAID Manager to set up hardware RAID after the Solaris OS is installed.


Configuring Adaptec RAID for x86 Servers With Any OS from the BIOS

This section describes how to use the Adaptec RAID Configuration Utility (ARCU) to create a RAID array. You can also use the procedure in this chapter to create single-drive volumes. A volume, by definition, consists of a single drive.

On servers equipped with an Adaptec SAS host bus adapter, all drives must be part of a volume before they can be used by the BIOS or the operating system. Adaptec controllers support single-drive volumes that can be used for drives that are not part of a RAID array. This is especially important when you add drives to a system.


Note - The Adaptec ARCU GUI uses the term “array” for a RAID volume and the term “volume” for a single-disk volume. An Adaptec array is synonymous with an LSI volume. The concept of a single-disk volume does not exist with LSI adapters.


  1. Power-cycle your server.

  2. During power up, type Ctrl-A to bring up the ARCU.

    A message appears, and then the ARCU opens.

  3. Select Array Configuration Utility.

    The Array Configuration Utility appears


    Adaptec RAID controller utility (ARCU) initial view.
  4. Select Initialize Drives.

    A list of drives appears.


    Adaptec RAID controller utility (ARCU) initial view.
  5. Select drives to initialize.

    Use the arrow keys to scroll through the list and use the Insert key to select a drive.


    Note - You can select many drives, and initialize them all at once, even if they are going to be in different volumes or arrays.


  6. When you have selected all the drives to be initialized, press Enter.

    A message warns you that initializing a drive erases array information from it.

  7. Type .

    The utility initializes the selected drives, and the main screen appears.


    Adaptec RAID controller utility (ARCU) initial view.
  8. Select Create Array from the main menu.

    A list of drives appears.


    Adaptec RAID controller utility (ARCU) initial view.
  9. Select the drives to be included in the array or volume.

    If you are going to create a one-disk volume, select the drive to be included in the volume. If you are going to create a RAID array, select all the drives to be included in the array. Repeat Step 9 through Step 13 for each subsequent array or volume.

    Use the arrow keys to scroll through the list and use the spacebar to select a drive.

  10. After you make your selections, press Enter.

    The Array Properties view appears.


    Adaptec RAID controller utility (ARCU) initial view.
  11. Make the following selections:

    • Array Type – Select an array type from the drop-down list. If you selected a single drive, the array type is Volume.

    • Array Label – Type a label.

    • Stripe Size – Type a stripe size.

    • Read Caching – Type or .

    • Write Caching – Select an option from the list.

  12. Press Enter or click Done to proceed.

    Depending on the Write Caching selection, a number of warnings might appear:

    • If the Write Caching setting is Enable always, and if you do not have a battery, or if the battery is not charged sufficiently, several warnings might appear. Type to proceed, or type to return to the Array Properties screen.

    • If the write cache is enabled, a write cache warning appears.
