The Escalade Storage Switch requires a workstation-class or server-class CPU whose bus complies with PCI 2.1 standards, and a PCI slot that meets the Plug and Play

and PC99 specifications. The storage switch requires one full-size PCI-bus slot. It may be connected to up to two, four or eight IDE/ATA drives by the supplied 40-pin, 80-conductor ribbon interface cables.

Note: The blue end of the ri bbon i nterface cable pl ugs into

the Escalade Storage Switch and the black end plugs into the drive.

Drives must meet UltraATA-100, UltraATA-66 or UltraATA-33 standards, but may be of any capacity or physical form factor. Length of unshielded interface cables may not exceed 18” (45.7 cm).

Personal safety

Warning! High voltages may be found inside computer

equipment. Before installing any of the hardware in this package or removing the protective covers of any computer equipment, turn of f power swit ches and discon nect power cords. Do not reconn ect the power cor ds until you have replaced the covers.

www.3ware.com 3

3ware Esca lade Storage Switch User Guide

Protecting equipment and data

Back up your data! Creating or deleting disk arrays

destroys existing files on the member drives. If your drives contain val uable dat a, back t hem up and save data elsewhere before changing your array configuration.

ESD precautions

Standard electrostatic discharge (ESD) precautions must be followed to avoid damaging computer components and accessories when installing or removing the Escalade Storage Switch.

• When the case of your comput er is op en and it s inter nal part s are exposed, don’t touch any internal part unnecessarily.

• Always wear a grounded strap or work on an ESD-protective mat.

• Don’t remove the storage switch from its protective bag until you are properly grounded.

• Handle the storage switch by its edges or by the black rail and metal bracket at its two ends.

• Don’t touch any pin, contact, lead or component on the storage switch.

Mechanical concerns

Be careful when installing the Escalade Storage Sw itch into your system. Excessive force can damage the board, the cables, your drives or your system.

• Be sure the board is aligned with its slot on the motherboard before installing. Do not flex the board excessively.

• Interface cable connectors must be mated carefully without bending any pins. The connectors provided a re keyed to prevent you from inserting them upside-down.

4 www.3ware.com

• The blue end of the interface cable plugs into the board and the black end plugs into the drive.

• Interface cables are fragile and must not be crimped or pinched. Ensure that they do not impe de the f low of cooli ng air f rom fans or heat sinks in the system case.

Introduction

Escalade Storage Switches allow you to use low-cost IDE/ATA drives in your storage system and still achieve performance levels and fault tolerance capabilities typically found in more expensive SCSI systems. Escalade S torage Switc hes are avai lable as two, four or eight port configura tions, as well as a shortened four or eight port versions designed for higher density rack-mounted applications.

StorSwitch architecture for scalable performance

The StorSwitch Architecture, found only in 3ware products, accelerates your storage sys tem’s performance by speeding data into system memory. Each drive has its own dedicated AccelerATA data IDE port, maximizing drive and system throughput.

RAID increases performance and adds redundancy

Escalade Storage Switches use Redundant Array of Inexpensive Disks (RAID) to increase your storage system’s performance and provide fault tol eranc e. The s torag e sw itche s of fe r RAID 0 varia ble striped arrays for performance; RAID 1 mirrored arrays for fault tolerance; variable striped mirrored RAID 10 arrays for fault tolerance and performance; and RAID 5 arrays for fault tolerance, high capacity an d storage efficiency.

RAID 0 arrays maximize performance and capacity

When drives are configured in a striped disk array (see Figure 1), the Escala de Storage Switch distribu tes large files across the multiple disks using RAID 0 techniq ues. St riped disk array s achieve high transfer rates because they can read or write data on more than one drive simultaneously. Striped disk arrays give exceptional performance, particularly for data intensive applic ations such as video editing, computer aided design and geographical information systems. Striping your disk array concatenates each drive’s capacity

www.3ware.com 7

3ware Esca lade Storage Switch User Guide

into one large volume. The stripe size is user configurable at 64K, 128K, 256K, 512K or 1M.

Figure 1. RAID 0 Configuration Example

RAID 1 arrays offer fault tolerance

Mirrored disk arrays write data to two drives using RAID 1 algorithms (see Figure 2). This gives your syste m faul t tole rance b y preserving the data on one drive if the other drive fails. Fault tolerance is a basic requirement for mission critical systems like web and database servers.

RAID -1

Figure 2. RAID 1 Configuration Example

TwinStor disk arrays

T ec hnology adds per formance t o 3wa re’s mirrored

RAID -1

Traditional mirroring techniques do little to improve performance. The adaptive algorithms found in 3ware’s TwinStor technology boost performance by distinguishing between random and sequen-

Introduction

tial read requests. For the sequential requests generated when accessing large files, both drives are u sed, with th e heads simu ltaneously reading alternating sections of the file. For the smaller random transactions, the data is read from a single optimal drive head.

Drives can be dynamically profiled, specifically for your brand of drive, during installation to customize the stripe size (for R AID configurations offering variable striping) and seek algorithms.

RAID 10 arrays maximize performance and fault tolerance

When drives are configured as a striped mirrored array, the disks are configured using bot h RAID 0 and RAID 1 te chniqu es, thus the name RAID 10 (see Figure 3). A minimum of four drives are required to use this te chnique. The fi rst two driv es are mirror ed as a fault tolerant array using RAID 1. The third and fourth drives are mirrored as a second fault tolerant array using RAID 1. The two mirrored arrays are then grouped as a striped RAID 0 array using a two tier structure. Higher data transfer rates are achieved by leveraging TwinStor and striping (64K, 128K, 256K, 512K or 1M) the arrays. RAID 10 is available on the four and eight port Escalade Storage Switches.

Figure 3. RAID 10 Configuration Example

www.3ware.com 9

3ware Esca lade Storage Switch User Guide

RAID 5 arrays optimize performance, fault tolerance, high capacity and storage efficiency

The RAID 5 configuration features the data striping of RAID 0 combined w i th the parity of RAID 4. Using a simpl e parity (exclusive OR) function, RAID 5 can tolera te the lo ss of one dri ve. Parity information is distributed across all drives rather than being concentrated on a single disk (see Figure 4). This avoids throughput loss due to contentio n for the pari ty drive. You can use hot spares to rebuild a failed drive “on-the-fly”.

RAID 5 capa city = size of smallest drive × (number of drives - 1). In addition, th e array’s storage efficien cy increa ses with the number of disks; from 66.7 % for 3 drives to 87.5 % for 8 drives: storage efficiency = (number of drives -1)

÷ (number of drives).

Unlike all other RAID configu rations that offer data stri ping, except for RAID 1, RAID 5 stripe s ize is limited to 64k.

Note: BIOS will reject the creation of a RAID 5 array

having less than 3 drives.

Introduction

R5 Fusion performance

Technology significantly improves RAID 5 write

3ware’s R5 Fusion significantly improves RAID 5 write performance for both large sequential and small random transactions. This advanced block caching firmware technology is combined with StorSwitch to deliv er extr emely hig h performanc e for RAID 5 write operations.

Note: R5 Fusion is available only with Escalade 7450

and 7850 storage switches.

Background Media Scan and Dynamic Sector Repair enhance data integrity

Background Media Scan is an embedded feature that performs a read-scan of all dis ks in an array. An error notification is posted fo r each read error detected (see “Screen Displa y Messages” on page 145). If the array is redundant (i.e., RAID 1, 10 and 5) Dynamic Sector Repair automatically recovers the redundant data and rewrites it to the logical defective location. The drive reallocates the sector where the read error occurred and a notification of repair is posted. This results in the restoration of drive and data integrity; the primary and redundant data are again both valid.

Configure and manage your disk arrays

The 3ware Disk Arr ay Conf igur ati on Ut il it y is a BIOS level tool for creating, deleting, maintaining disk array s and rebuilding mirrored arrays. From the 3DM Disk Array Configuration Utility, you can also specify hot spares from available drives to be dynamically subst ituted for a failed drive in a mirrored array. Refer to the 3ware Disk Array Configuration Utility chapter.

SMART Monitoring (Self-Monitoring, Analysis and Reporting Technology) adds monitoring and troubleshooting functionality by

www.3ware.com

3ware Esca lade Storage Switch User Guide

automatically chec ki ng a di sk drive's health and repor ti ng pot ent ial problems. It allows you to take proactive steps to prevent impending disk crashes.

3DM Disk Management Utility runs in the background on the Escalade Storage Switch’s host and allows you to monitor the switch and rebuild mirrored arrays remotely via a standard web browser. To remotely a ccess 3DM, you are not required to insta ll any software on your system but you must have access to the network with the Escalade Storage Switch. 3DM supports hot spare and hot swap for mirrored arrays. Hot swap allows users to replace a failed drive in a mirrored array whi l e the system remains up. Refer to the 3DM Disk Management Utility chapter.

To create, delete or verify arrays, you must use the 3ware Disk Array Conf iguration Utility. To check array configuration or status, disable write cache, select a hot spare or rebuild a mirrored array, you can use the 3ware Disk Array Configuration Utility at BIOS time or 3DM Disk Management Utility in real time . Hot swap is only available through the 3DM Disk Management Util-

ity.

To remove an existing Escalade Storage Switch

1 I f the computer is running, shut it down. Turn off power to the

computer and disconnect the power cord from the outlet.

2 Open the computer case according to the manufactur er’ s in struc -

tions.

3 Disconnect the disks from the existing Escalade Storage Switch

installed in your system. If your boot disk is connected to the storage switch and you intend to retain it as your boot device, note or mark which physical disk is connected to slot 0 on the switch. This disk should be reconnected to slot 0 on the new storage switch. Preserving the slot order of how the other drives are connected is unimportant, even if the disks are part of a disk array, although it is recommended that a plug-to-plug replacement is followed.

4 Remove the screw in the metal bracket at the end of the old stor-

age switch. Save the screw for installing the new switch.

5 Gently remo ve the storage switch fro m the PCI slot . 6 Remove the cables from the storage switch and discard. Reusing

interface cables is not recommended.

Connect the interface cables to the Escalade Storage Switch

1 Connect the interface cables supplied with the product to the

storage sw itch.

Note: UltraATA-66 and UltraATA-100 drives

require 40-pin, 80-conductor ribbon cables. These cables have color coded ends. For optimum performance, the blue end must be connected to the storage switch and the black end must be connected to the hard drive.

2 One edge of each interface cable should have a colored (usually

red) line denoting the conductor to Pin 1. Align the storage

18 www.3ware.com

Hardware Installation

switch so that the colored line is toward the top edge of the switch. Mate the connectors carefully without bending any pins.

3 I nstall the other connectors in the same manner.

Install the Escalade Storage Switch in the computer

1 I f the computer is running, shut it down. Turn off power to the

computer and disconnect the power cord from the outlet.

2 Open the computer case according to the manufacturer’s instruc-

tions.

3 Find the PCI slot you want to use for the storage switch.

Hint: Cable routing may be easier if you install the

storage switch next to an open slot.

4 Remove the metal filler bracket for the slot. Save this screw; it

will be used to secure the storage switch after you have seated it in the slot.

Hint: While the storage switch runs properly in any

PCI slot, not all slots give equal performance du e to the architecture of the PC I bus. In our laboratories, we have noticed that the slots closest to the Accelerated Graphics Port (AGP) typically give the best performance.

5 Line the storage switch up so that all pins make proper contact

with the PCI slot pins when pu shed into plac e. The black end r ail opposite the metal bracket may be removed if needed to fit the storage switch inside the chassis. The short 4-port or 8-port Escalade Stor age Switc h is keye d to ensu re prope r insta llation in a full-sized PCI slot.

www.3ware.com 19

3ware Esca lade Storage Switch User Guide

6 Ensure that the contacts will mate with both grooves in the slot.

Press down gently on the edge of the storage switch directly above the slot until the it is fully seated.

7 Check that the storage switch’s metal bracket covers the hole in

the case and secure the bracket with the screw that was used to secure the filler bracket in step 4.

Connect the drives to the interface cables

1 Be sure to use the supplied cables. With the higher speeds of

UltraATA-100 and UltraATA-66, using quality cables is important.

2 Before connecting your drives, check your drives’ jumper set-

ting. The range of settings provided vary by manufacturer as do the method for adjusting them. Refer to information provided with your drives for the me th od re qui red to set them. To operate properly, the Escalade Storage Switch r equi res that drives be se t as Single (if available on your drive) or Master.

3 I f your drives are not already installed in the computer chassis,

do so now. Be sure that the drives are connected to the power supply. Y-splitter power suppl y co nnec tors are included in some kits in case you need additional power supply connections.

4 For each drive, select the black en d of a n int erfac e cabl e n ot con -

nected to the storage switch and plug it into the drive or drive carrier. The cable’s colored edge denotes Pin 1 and should be adjacent to the 4-pin power plug.

Check your installation and close the case

1 After all of the drives are connected to the storage switch and it

is installed in its slot, verify that th e cables do no t interfere w i th the operation of any other components in the case or block the flow of cooling air.

2 Close the case and reconnect the power cables.

20 www.3ware.com

Hardware Installation

Check motherboard boot sequence

Using your computer’s Setup utility, ensure that your boot device precedes the Escalade Storage Switch in the boot sequence. If you have other disks installed on the motherboard, the storage switch precedes them in boot order.

3ware Disk Array Configuration Utility

The 3ware Disk Array Configuration Utility all ows you to crea te disk arrays by combining disks, deleting disks or breaking disk arrays back into their member disks. You can also specify an available drive as a hot spare. If an array becomes degraded, the hot spare will automaticall y be substitu ted for the fau lted drive.

Note: The BIOS will not be in stalled if no drives are

attached to the Escalade Storage Switch. The storage switch shares one IRQ on the PCI bus.

Hot Spare and Hot Swap

Hot Spare is the label given to a drive that is available, active and designated as a spare. This designated drive is applied automatically when a drive deg rades and the a rray is r ebuilt. Hot Swap is the term applied to the process of swapping out a degraded drive, programmatically and using 3DM, with a pre-assigned spare.

There are two methods for adding a drive as a spare. You may designate a drive as a Hot Spare during the BIOS page display, or you may designate a drive as a Hot Spare through the 3DM configure page. These two methods are discussed below.

BIOS Screen

When designating spare in the BIOS screen, it is assumed that as you are creating your array, you are “setting aside” drive(s) as Hot Spares. This is done by using the S key on the selected drive. Leaving a drive undesignated results in it becoming a JBOD drive. JBOD drives become available to the operating system as d i stinct volumes, and, consequently, they cannot be designated as spares at

www.3ware.com 23

3ware Esca lade Storage Switch User Guide

a later time. I f a s pare is de sig nated in th e BIOS s creen, th e desi gnation and configuration is in effect from this point on. The spare drive will be displayed as a Hot Spare in the 3DM configuration page.

3DM Configure Page

In order to designate an available drive as a spare from the 3 DM configure page, you must ensure that the drive is not a JBOD drive. To designate a drive as a Hot Spare from this page, you must use one of the two following methods:

1 Install the drive at the operating system level while the syst em is

powered. This should only be done with an approved and recognized drive-carrier swap. If you do not use an approved and recognized drive-carrier swap, connecting interface cables and power cables can/will crash the system from bus or power supply issues.

2 Shut down the system (Windows/Linux system shutdown);

install the drive and do no t go int o the BI OS scree n. When 3 DM is invoked, the configuration page may show this drive as dead. Select Issue a Removed Drive and then select Add Spare. The drive should appear as a Hot Spare.

Invoking the 3ware BIOS tool

Reboot your system. During the boot phase, wait until you see a screen similar to Figure 6.

24 www.3ware.com

3ware Disk Array Configuration Utility

Figure 6. 3ware BIOS Tool

Press Alt-3 immediately to bring up the 3war e Disk Arr ay Config - uration display.

Note: If drives are attached and you do not want to

install the 3ware BIOS, press Alt-b to bypass the BIOS installation.

Exiting the 3ware BIOS tool

To save your configuration modifications hit the F8 key. After you have hit the F8 key to commit yo ur changes , a li st of af fect ed drive s will be displayed and you will be asked to confirm your configuration. The booting process will resume. If you have selected mirrored arrays after the operating system is running, the Escalade Storage Switch will automatical ly run a backgroun d initializat ion to verify that both disks in the arrays are identical.

3ware Esca lade Storage Switch User Guide

To exit the 3ware Disk Array Configuration Utility without saving your changes hit Esc.

Determining your configuration

Caution: Configuring a disk array writ es for mat-t ype

data onto it s member disks and overwrites all the files on those disks. Be sure to back up data that requires retention.

With a 2-port Escalade Storage Switch you are limited to a twodrive JBOD (Just a Bunch of Disks), or a two-drive RAID 0 or RAID 1 array. With a 4-port Escalade Storage Switch, you can combine two to four disks into a single array. With four disks you can create a four-drive RAID 0 array, two RAID 1 arrays, one RAID 5 array or one RAID 10 array.

The 4-port configuration can be duplicated using the 8-port Escalade Storage Switch. In addition, you may also create a five, six, seven or eight-dr ive RAID 0 or RAID 5 arra y, or an eight-drive RAID 10 array .

The 3ware Disk Arra y Configur ation main displa y shows the current disk drive configuration.

• Av ailable Drives reports independent drives (JBOD) not ass oci ated with an array.

• Disk Arrays lists any existing arrays along with their member disks and hot spares.

Select RAID configuration

The Escalade Storage Switch gives you a choice of four RAID configurations. Select one.

• Stripe (RAID 0): maximizes performance a nd capacit y through a process called striping. High performance arrays write portions of a single file across multiple drives. There is no fault tolerance.

• Mirror (RAID 1): duplicates or “mirrors” the data on both drives. No data will be lost if one of the drives fa ils.

• RAID 10: combines mirr or ing and striping, providing both fault tolerance and high performance. RAID 10 arrays require a minimum of four drives. Configurations consist of 4, 6 or 8 drives.

• RAID 5: combines parity da ta and stri ping, pr ovidin g fau lt toler ance, high capacity and high storage efficiency. The parity data is distributed acr oss all drive s, rat her t han be ing con cen trate d on

a single disk, to avoid throughput loss due to corrections for the parity drive. RAID 5 arrays requires a minimum of three drives. Configurations consist of 3, 4, 5, 6, 7 or 8 drives.

Select striping size

For a RAID 1 or RAID 10 configuration select the striping size. Sizes of 64K, 128K, 256K, 512K or 1M are selected using the Stripe Size box shown in Figure 10. RAID 5 only allows a 64K stripe size.

Select write cache properties

The Escalade Storage Switch gives you a choice of disabling the write cache for your disk arrays. Wr ite cache is used to store data locally on the drive before it is written to the disk, allowing the computer to continue with its next task. Enabling the write cache results in the most efficient access times for your computer system.

32 www.3ware.com

3ware Disk Array Configuration Utility

There may be instance s when you always wa nt the computer to wait for the drive to write all the data to disk before going on to its next task. For this case, you must disable the write cache. To disable the write cache, select disable from the array’s Write Cache State selection. The default for Write Cache State is enable.

Confirm array configuration

Select the OK button to confirm creating the array or Cancel to reject it. The array is not actually created and no data will be overwritten until you have finished making all your changes and select the F8 key.

For RAID 5 Arrays

Because of the Read-Modify-Write operations, zeros are first written to all dri ves in the array before th e array is functional. The screen shown in Figure 12 appears after selecting OK to confirm array creation.

If the write-zeros ope ration is aborted by th e user fo r any reason the unit will go into initializing mode when restarted. This mode scans the entire array to verify parity. If coherency problems appear the parity will be corrected to match the data found on that stripe.

Caution: When running in initiali zing mode th e arra y

is not redundant. You cannot remove any drive.

For RAID 1 or 10 Arrays

Drives are dynamically profiled, specifically for your brand of drive, after selecting OK to confirm array creation. This is done to customize the stripe size (f or RAID configuratio ns offering var iable striping) and seek algorithms.

Specifying a hot spare

The Escalade Storage Switch gives you the option to specify a hot spare from one of your Available Drives. If a hot spare i s s p ec if ie d and the mirror degrades, an event notification will be generated. The hot spare will dynamically replace the failed drive in a mirrored array without user intervention. Select a hot spare by navigating to an Available Drive. The Toggle Hot Spare verbiage at the bottom of the screen will be black if the drive can be used as a hot spare. Enter s to select the hot spare or to disable the hot spare if it is already enabled.

Note: Hot spare drives need to have the same or larger

storage capacity than the RAID 1, RAID 5 or RAID 10 drives.

Changing an existing configuration

1 Back up any disk arrays that contain data that you want to retain

before the configuration change.

2 Create new disk arrays fo llowing the instructions in the Deter-

mining your configuration, Creating a disk array and Deleting a disk array sections. You may need to delete existing

arrays to free up disks first. 3 Boot, partition and format any new disk arrays or free disks. 4 When you are finished configuring, restore from backup any

data saved from previous disk arrays

Modifying a disk array

To modify an existing array you must first delete it then recreate it with the new drives. As with all disk array operations, there is no way to modify an existing array without overwriting data on the drives involved.

How to maintain or verify a disk array

The Maintain Disk Array (see Figure 14) shows the current disk array configuration that you have selected. The array’s Write

Cache State can be changed. Refer to Select write cache properties paragraph in the Creating a disk array section. Verify Array

can be specified as no or yes. The default is no. Yes launches a fore- ground process that checks the data integrity of a fault tolerant array. If the verify array process determines that the mirrored drives are not identical or the parity is not correct, the mirror is degraded and the rebuild process is launched.

Rebuilding a mirrored disk array

Escalade Storage Switches allow you to create fault tolerant disk arrays by selecting a mirrored RAID 1 or RAID 10 array. These disk arrays store identical data on two or more drives to protect against drive failur e. If one or more of the drive s of a mirrored arr ay is removed, unplug ged or f ails on read or write requests , the array is marked as DEGRADED and the drive is marked as Not In Use (see Figure 15 and Figure 16).

You can still read and write data f rom a de graded di sk arr ay, but the array will not be fault tolerant until it is rebuilt using the Rebuild feature, described in the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility chapters.

Auto rebuild on power failure

During driver startup 3ware’s auto rebuild f eature sets a flag indicating that the driver loaded. Upon an orderly shutdown the flag is rewritten, indicating a clean shutdown. During the next system power cycle the firmware queries the flag. For a RAID 1 configuration, if there was a problem, the firmware degrades the secondary drive in the array and starts the background rebuild of the mirrored drive. When the rebuild is co mplete the two halves of the m irror will be resynchronized. For a RAID 5 configuration, if there is a problem, the firmware starts the background verification that checks that the parity matches the data.

Has your boot drive been partitioned?

Microsoft Windows NT 4.0 Setup occasionally has problems installing on drive s that hav e not bee n partit ioned. If y ou are havi ng trouble you may need to create a partition on the drive where you plan to install Windows NT 4.0.

1Use the FDISK DOS utility to get your disk partitioned and

ready for installation quickly: 2 Boot MS-DOS and use FDISK to create a partition on the boot

drive. The partition does not need to be formatted or made

active. Wit h FDISK you are limited to 4 GB for your boot parti-

tion. If you need a larger boot space create a single small (e.g.,

100 MB) partition, then adjust the size during Windows NT 4.0

Setup.
