1Basic Storage Array Information
This chapter includes information about the location and basic operation of the replaceable
components in astorage array, tools and equipment you will need, protecting hardware from
electrostatic discharge, and power on and off operations.
About the PS6610 Array
The PS6610 array is aPS6x10 10GbE class EqualLogic PS Series array that continues the focus by
Dell on industry-standard features and capabilities for the midrange iSCSI SAN market. PS Series
Storage Arrays version 8.0 introduces the PS6610.
PS6610 Features
The PS6610 array is a5U chassis that can be configured with either 42 or 84 drives. Both 2.5-inch
and 3.5-inch drives are supported in either configuration. Features of the PS6610 include:
• Two hot-swappable Type 18 control modules, which contain increased memory (16GB per
controller) and amore powerful processor than previous generation controllers.
• 5U SAS Drive Enclosure
• Ethernet ports:
– Two pairs of 10Gb/s dual-media interfaces (10GBASE-T/SFP+)
– Ability to fall back to 1GB/s interface (10GBASE-T ports only)
• Support for ReadyRails™ II
Front-Panel Features and Indicators
The main features of the front panel are shown in Figure 1and identified in Table 1.The left and
right sides of each drawer on the PS6610 each contain an anti-tamper lock (see Figure 2), arecessed
handle for opening the drawer, and asideplane status indicator (see Figure 3)that monitors the
operation and activity of each sideplane. As you face the front of the chassis, an Enclosure Status
Indicator is located on the left edge that provides status information for the entire array (see Figure
4).
• Table 2describes the sideplane status indicators located on the drawers.
• Table 3describes the enclosure indicator.

Recommended Tools
• When performing any type of work on the PS6610 array, including inserting and removing disk
drives, you should always wear awrist grounding strap (not provided) to protect the hardware
from electrostatic discharge. See Hardware Protection.
• To lock and unlock the drawers on the array, you will need aT20 Torx key (provided).
Hardware Protection
When handling array hardware, use an electrostatic wrist strap (not included) or asimilar form of
protection to protect your PS Series array from electrostatic discharge. To use awrist strap:
1. Connect the steel snap on the coil cord to the stud on the elastic band. See Figure 6.
Figure 6: Using an Electrostatic Wrist Strap
2. Fit the band tightly around your wrist.
3. Connect the band to ground. You can either plug the banana connector into amatching grounded
receptacle, or attach it to the matching alligator clip and connect the clip to agrounded device.
Examples of an appropriate ground would be an ESD mat or the metal frame of agrounded piece
of equipment.
Shutting Down and Restarting an Array
The PS6610 array includes redundant, hot-swappable drives, power supplies, and control modules.
You can remove aredundant component without affecting operation as long as afunctioning
component is available. Otherwise, Dell recommends that you cleanly shut down the array and turn
off power before removing acomponent.
Note: When an array is shut down, any volumes with data on the array will be set offline until the
array is successfully restarted. Being offline affects initiators that are connected to the volumes.
Array shutdown and restart procedure
1. Connect to the array in one of the following ways:
6

PS6610 Hardware Owner's Manual 1Basic Storage Array Information
• Use telnet or SSH to connect to afunctioning IP address assigned to anetwork interface on the
array. Do not connect to the group IP address.
• Use the null modem cable, shipped with the array, to connect the serial port on the active
control module (ACT LED is green) to aconsole or acomputer running aterminal emulator.
Make sure the serial line characteristics are as follows:
• 9600 baud
• One STOP bit
• No parity
• 8data bits
• No flow control
2. Log in to an account with read-write access, such as the grpadmin account.

2Drive Maintenance
You can replace afailed drive while the array remains running.
Supported Drives and Drive Types
Depending on your configuration, your array supports either 42 or 84 of the 2.5-inch and 3.5-inch SAS
nad NL-SAS drives in internal drive bays. SSD drives are also supported in ahybrid configuration.
Drives are connected to the midplanes and backplane through drive carriers and are hot-swappable.
Drives are supplied in acarrier that is keyed to fit into aspecific array model. The drives cannot be
installed in other Dell arrays or in arrays not from Dell.
Note: Dell uses specially qualified and tested hard drives for its EqualLogic storage systems, and
manages hard drive quality and firmware only for those drives. As aresult, only Dell-provided hard
drives are supported by PS Series arrays. Attempts to use unapproved hard drives in the PS6610 array
will not be successful.
Mixed-Drive (Hybrid) Arrays
The PS6610ES supports acombination of fourteen (14) solid state drives (SSDs) and seventy (70)
rotational drives (HDs) in the array. The proportion of SSDs to HDs cannot be changed. SSDs must
all be installed in the same row in slots 0-13. See Disk-Drive Slot Numbers on page 10.
Drive Installation Guidelines and Restrictions
It is extremely important to install the disk drives properly and maintain the performance of disk
drives to ensure optimal operation of the array.
Only two drive configurations are supported: the half-populated array (42 drives) and the fully-
populated array (84 drives).
Caution: In ahalf-populated array, the drives must be installed in specific rows across both drawers
of the array. In afully-populated hybrid array, the SSDs must be installed in aspecific row. See the
following list for more information.
The following restrictions apply when installing disk drives:
• When installing 42 drives, the array must have 2complete rows of HDs in the top drawer (slots
0-27) and 1complete row of HDs in the bottom drawer (slots 42-55). See Disk-Drive Slot
Numbers on page 10.
• When installing 84 drives, an optional hybrid configuration can be purchased that combines
exactly 14 SSDs with 70 rotational drives (HDs). In hybrid arrays, the 14 SSDs must be inserted
in the front row of the top drawer (slot locations 0-13). The proportion of SSDs to HDs cannot be
changed. See Disk-Drive Slot Numbers on page 10.
• Do not leave any drive slots empty in apopulated row. Operating an array with an empty slot will
void your warranty and support contract.
Drive Handling Requirements
When handling hard drives, take the following precautions:
9

PS6610 Hardware Owner's Manual 2Drive Maintenance
• Protect drives from electrostatic discharge. Wear an electrostatic wrist strap when handling a
drive. See Hardware Protection on page 6.
• Store drives properly. Store replacement drives in the packaging in which they were shipped. Do
not stack drives or place anything on top of adrive.
• Handle drives carefully. Hold adrive only by the plastic part of the carrier or the handle. Do not
drop, jolt, or force adrive into aslot.
• Warm replacement drives to room temperature before installation. (Consider letting anew
replacement drive sit overnight before installing it in an array.)
• Do not remove adrive from its carrier. This action will void your warranty and support contract.
• Keep the shipping material. Return afailed drive to your array support provider in the packaging
in which the replacement drive was shipped. Shipping drives in unauthorized packaging might void
your warranty.
Drive Maintenance Requirements
Disk drives must be installed properly and in aspecific configuration to allow for the necessary
airflow and cooling throughout the chassis. Failure to do so will trigger awarning condition.
• Failed drives should be replaced as soon as possible. However, if adrive fails and areplacement
is not readily available, leave the failed drive in the slot until it can be replaced.
• When installing drives in the array, apply firm downward pressure with both hands and slide the
drive toward the rear of the drawer until it snaps into place and the locking latch is fully engaged.
See Install Disk Drives on page 12.
• When correctly installed in the drawer, all top-facing drive surfaces should form aflat and level
surface. If adrive is protruding upward in any way, reinstall the drive.
• After installation, verify that the drive power LED is green or flashing green.
Disk-Drive Slot Numbers
Disk-drive slots in the top drawer are numbered as shown in Table 5.The disk-drive slots in the bot-
tom drawer are numbered as shown in Table 6.

PS6610 Hardware Owner's Manual 2Drive Maintenance
Array Behavior When aDrive Fails
The PS6610 firmware uses acopy-to-spare operation to replace failing drives. This operation can, in
many cases, improve the performance of the drive replacement process by avoiding afull RAID
rebuild, which provides better reliability.
Note: If adrive fails, replace it. Do not reinstall it in the array. If areplacement drive is not available,
keep the failed drive in the array until it can be replaced.
If aSpare Drive Is Not Available
If aspare drive is not available, the RAID set will become degraded and performance might be
impaired. However, aRAID 6set can survive two simultaneous drive failures.
If aspare drive is not available and the failed drive is in aRAID set that is already degraded, data
might be lost and must be recovered from abackup.
Identifying Failed Drives
Adrive failure is indicated by:
• An LED located on the drive. See Interpreting Drive LEDs on page 11.
• An LED on the Enclosure Status Indicator.
• Amessage in the event log or in the Group Manager Alarms panel.
• Indications in the Group Manager group member Disks tab or the CLI member select show disks
command output.
Inside each drawer, aDrawer Slot Label located on top of the sideplanes shows the drive numbering
within each row. See Disk-Drive Slot Numbers on page 10.
Interpreting Drive LEDs
The drive LED is shown in Figure 7.The drive LED states are described in Table 7.

Installing and Removing Disk Drives
The proper insertion and seating of hard drives in the chassis drawers is critical to the operation of the
array. For proper cooling, do not remove afailed drive until it can be replaced with another.
Note: You should always wear electrostatic protection when handling adrive. See Hardware
Protection on page 6.
Install Disk Drives
The 3.5-inch drives and 2.5-inch drives come preconfigured in their carriers (DDICs) and are installed
vertically into the top of the open drawer with the large arrow pointing toward the rear of the chassis.
Note: Installing adrive is easier if you work from the side of the open drawer.
1. Hold the drive by the carrier and slide the drive most of the way into aslot.
2. Using both hands (thumbs and forefingers), apply downward pressure firmly and equally across
the carrier (see Figure 8).
3. While maintaining downward pressure, slide the drive carrier's top plate toward the back of the
drawer until the release button in the center clicks into place (see Figure 9).
Note: It is possible for adrive to appear seated but not be fully locked into position, eventually
causing it to dislodge itself. After installing adrive, check the release button in the center of the
carrier. If the drive is not fully locked into position, ayellow line will be visible underneath the arrow
button. If the yellow line is visible, remove the drive and reinstall it.

4. Verify that the new drive is operational by examining the LED on top of the DDIC. (An amber
LED indicates that the drive is working properly.) In addition, you can examine the GUI group
member Disks tab and the CLI member select show disks command output to check the status of
all drives in the system.

PS6610 Hardware Owner's Manual 2Drive Maintenance
Remove Disk Drives
Note: Removing adrive is easier if you work from the side of the open drawer.
1. Using two hands, apply firm downward pressure to the top surface of the drive carrier.
2. While maintaining downward pressure, use one finger to press the release button on the center of
the carrier and push it in the direction of the arrow (callout 1in Figure 10). The drive latch opens
and the drive will emerge partway from the array.
Caution: When removing an active rotational drive, allow the drive to spin down for afew moments
before removing it fully from the drive bay.
3. Pull the drive out by its carrier until it is free of the drive bay.
