Overview

This training is delivered as a blended learning course

Web based blended learning Interactive Simulations Video demonstrations Remote access to equipment

Additional information is available in the accompanyingweb pages

CX4 Series Storage Array range

4 Enclosures CX4-120c CX4-240c CX4-480c CX4-960c

CX4 = Fourth generation of Hardware

In a similar way to the previous release of CXhardware the last 3 digits indicate the maximumamount of connected drives


5/67

New Features

Flexports Modular Front end port configurations

Greater Resilience GWCA (Greater Write Cache Availability)

Up to 960 Drives64 bit operating system

IPV6 capability


6/67

Cache

Greater Write Cache AvailabilityTwo Independent Features Persistent Memory

Cache retained through Storage Processor restarts Recovery algorithms obtain last valid write cache data

Enhanced Performance Increased Write cache Write cache enabled in degraded mode

Restarts, NDUs etc.

Power Requirements

2U Chassis operate on 110V or 240v CX4-120 / 240 and 480

4U Chassis operate on 240v only CX4-960

Care must be taken in allocating power

I/O Modules

I/O Modules in each Storage Processor must match

I/O Modules can be added with Data in Place Utilizes NST wizard to install and configure modules

Once a port is added and persisted it cannot bechanged


31/67

Replacing an I/O Module

I/O Modules are not hot pluggable Use CLI to shutdown the affected SP

Naviseccli h -user -password

-scope 0 shutdownsp Make note of labels and remove all FE and BE Cables Replace the I/O Module

Reboot the SP

Use CLI pointed to the running SP Naviseccli h -user -password

-scope 0 rebootpeersp Verify operation in Navisphere Reconnect all cables into correct locations

LED Codes

Fault LED is a bi-color LED andindicates boot status

Amber Hz = BIOS 1 Hz = POST 4 Hz = POST starting OSBlue Hz = OS Booted 1 Hz = FLARE Driver start 4 Hz = Flare Driver complete

Power LED only = successful boot

Navisphere Domains

To Manage CX4 Arrays the Navi UI must be release 28In a storage domain with multiple storage systems ofdifferent generations the domain master must be one

of the following. CX4 series on Release 28 CX3 series on Release 26 CX series on Release 24

OrOff Array management must be used where theNavisphere UI version is release 28

Zoning

Open zoning to be used with caution More Front end ports Maximum initiator counts per SP

Mirrorview Ports

No longer just the highest port on the ArrayMirrorview ports are assigned by Flare at initial Poweron of array

If additional Front end ports are added the Mirrorviewport will remain in the same place
