DAE2-ATAATA Drive Enclosure for CX Arrays
This module introduces a new DAE2 to the CX family called DAE2-ATA. It consistsof a standard DAE2 enclosure and power supply/fan assemblies. New LCC cardsreplace the old LCC cards and all disk drives in the enclosure are commodity ATAdisks. Drives in the enclosure must be the same type. ATA enclosures can bemixed in an array with existing FC enclosures. Upon completion of this module thestudent will be able to:

Automatic Write Defect Reallocation
The ATA disk drives used provide data in 512 byte blocks on a parallel interface.Using 5400 RPMs for a spindle speed yields an average seek time of 12ms.
The drives use zone density recording which provide fewer sectors on inside tracks
and more sectors on succeeding tracks as the heads move towards the outer trackson the disk.
An Ultra ATA/133 interface controller can provide read-ahead mode based on aprevious read history algorithm. Also, Automatic Write Defect Reallocation (badblock detection) is provided so bad sectors can be remapped to another place onthe disk.

Disk Drive Paddle Card
Provides Dual-Port Capability to ATA Disks
Performs Serial-to-Parallel Signal Conversion
A Micro Processor Chip Controls : Disk Environmental Functions LED Disk Drive Power-Up Sequence, etc.)
The paddle card sits on the drive carrier between the ATA drive and theDAE2 mid-plane. The paddle card controls power to the ATA drive. Thepaddle card converts the standard ATA interface into Serial and dual portedfor use in the DAE2 for high availability. The paddle card is not a FRU, it is apart of the disk module.
The paddle card on the disk drive carrier performs several functions. Itprovides Dual-port capability so drives can be accessed by either of the twoFibre loops this is the same capability as in the Fibre channel enclosureusing Fibre channel drives. Since the interface to the disk from the paddlecard is parallel, conversion to serial is required when providing information tothe DAE2 enclosure. Also provided on the paddle card is a microprocessor.It causes the disks to spin up in sequence starting with disk 0, then 1, etc.The microprocessor also monitors environmental conditions and signals theserver when a problem occurs, Also the micro is responsible for illuminatingthe LED on the front of the drive.

Environmental Monitoring
One purpose of the Bridge Controller Card (LCC) is to convert all signaling (control anddata) from the ATA interface from the disk drive into the Fibre Channel interface for theDAE2 that can be used by the other components in the array (other DPE2s and StorageProcessors).
A LCC supports and controls one Fibre Channel loop and monitors the DAE2. The LCCs ina DAE2 are connected to other Fibre Channel devices (hosts and DAE2s) using twin-axialcopper cables. The cabling is not explicitly configured as a loop, but instead, as a set of full-duplex, point-to-point connections with the last disk enclosure in the chain closing the loopon its LCC.
The LCC passes the input signal to the disk drives in the enclosure then sends the outputsignal, via cables, to the next DAE2 in the loop. ATA link control cards (LCCs) provide thesame Fibre channel input and output, but convert those signals to and from the ATA 6protocol used by their disk drives. Each LCC independently monitors the environmentalstatus of the entire enclosure, using a microcomputer-controlled FRU (field-replaceable unit)monitor. The FRU monitor (FRUMON) communicates status to the server.
Each LCC independently monitors the environmental status of the entire enclosure, using amicrocomputer FRU monitor. The FRU monitor communicates status to the server. Theprotocols let the server poll DAE2 status and send commands that control the LCC portbypass circuits and the disk-module status lights. The protocols do not let the LCCscommunicate with or control each other. Each LCC has four status lights.

As shown in the drawing, ATA and Fibre Channel enclosures can be mixed in thesame array. The only rule that cannot be broken is the first enclosure MUST beFibre Channel and contain a minimum of five disks. Notice that the amount of totalstorage in an enclosure varies with the drive size. The example chosen was using73Gb FC drives and 250GB ATA disks.

GUI Interface changes
In order to manage the DAE2-ATA enclosure Navisphere 6.4 is required. For allitems associated with an ATA enclosure notice that Navisphere 6.4 identifies thoseitems with the letters ATA. Under Physical, the second enclosure is identified asBus 0 Enclosure 1 (DAE2-ATA). Notice also that the Icon for that enclosure alsocontains the letter E which stands for Empty. This means that at least one diskslot is empty. Each empty slot must be occupied with a blank carrier for coolingpurposes.
Under the RAID Groups icon, RAID group 2 is identified as a RAID 1 (mirrored pair)and is using ATA disks. When RAID group 2 is expanded you can see that disks 0and 1 are being used to form the RAID group and they are ATA disks.
A further breakdown, shows that LUN0 is a part of RAID group 0 and again isshown using ATA disks.

Alternate Management Topology
ManagementStation
Connection from serial port on management station to the serial porton a Storage Processor
Using a NULL MODEM CABLE
Using a PPP Connection at 115,200 baud (Dial-Up Networking)
DHCPIP: 192.168.1.10
IP: 192.168.1.1
Reasons for using CLARiiONs PPP option
On a new array, there is no Ethernet / TCP-IP connectivity, so this is the methodfor configuring the array (initialization)
There are problems with the tpc/ip network or settings.Customer security issues prohibit maintainers to operate on the customers tcp/ipnetwork.
Means of establishing this connection
Using a Null Modem serial cable, connect from a serial port on the workstation tothe serial port (marked |0|0|) on the Storage Processor
Configure a Dial-Up Networking Session on the workstation (see ProcedureGenerator for details)
Connect to the array using Dial-Up Networking session, using user: clariion, pw:clariion! (include !)
The array will auto-assign an IP to the workstation and present the StorageProcessor as 192.168.1.1.
This will allow use of the Management UI, though it will be limited to the singlestorage processor, and will be far slower than the ethernet topology
This allows for access to navicli commands to that storage processor
Finally, this method can be used as back door method for lost domain passwords
etc.

Other Array Settings
On a new system, you will need to COMMIT the BaseSoftware before proceeding with any other settings.Set the Date and Time on the SPs.Give the array a Unique nameChange the speed of one or more of the SP FE Ports.Enable Cache and Statistics Logging
All of these steps will be practiced in the CLARiiON HostIntegration Workshop
Until the Base or array software is committed, the array will not be fullyfunctional. This step also needs to be completed after each Base Softwareupgrade
It is important to set the date and time on the array so that the event logs oneach Storage Processor are accurate. You only need to configure the timeon a single Storage Processor and it will propagate to the other.
The name given to an array by default in the Navisphere interface is theSerial Number. While this is ok in some circumstances, it may provecumbersome in an environment with multiple arrays. Giving a logical nameto the array may ease identification.
The default speed of the Front-End ports is 2Gbit. If these ports are beingcabled to a legacy environment, such as a host with a 1Gbit HBA or 1Gbit
switch, you will need to change the speed on all ports involved. It has to bedone to each individual port and is a live, real-time software operation inNavisphere.
Cache is not enabled by default. You will need to enable it to thecustomers specification before the end of the configuration.
The workshop will cover all the necessary software steps to complete theinitialization.

Non Disruptive Upgrade
Means by which a CX-Series array can have features
added or upgraded without disrupting host access.Requirements to be non-disruptive: Hosts must have an active connection to both Storage
Processors. Hosts must have PowerPath software running and properly
configured. Cache settings should be recorded.
Requirements for successful upgrade: If upgrading software currently on an array, all software must
be upgraded at once. If adding software to an array, all pre-requisites must be met. See Software Compatibility Matrix for details

1. Through the software Installation Wizard, the admin chooses the .ndu files tobe upgraded.
2. The array then checks for the validity of the files and whether all the pre-reqs and
dependencies will be met.3. The .ndu files are then copied to the PSM area of the array.
4. The PSM then extracts the Driver files from the .ndu files
5. It will then update the Storage Processor it determines is the Secondary StorageProcessor (usually SPB), with the new software.
6. It will then de-active the old software and activate the new software.
7. That Storage processor will reboot. It is up to the host to failover to the other SPby having PowerPath installed and a valid path to the other Storage Processor.
8. When the SP, is done booting, it will repeat steps 5-7 for the other SP.

ManagementStation
CLARiiON management topology is designed to be out-of-band, using aethernet/tcpip network for management. A management station and all of thearrays you wish to manage need to all be on the same tcp/ip network. This doesnot mean they need to be on the same subnet. The need to be reachable to eachother over tcp ports 80, and 443 (or alternatively, if these are not an option 2162and 2163). Also, both Storage Processors on each managed system need to be onthe network.
The Management Workstation is where we run the Navisphere interface. If youwish to manage all arrays within a single UI, one needs to be selected as theDomain MASTER. In this diagram, the CX600 has been chosen to be theMASTER. But any array running Navi Mgt Server can be a MASTER. The other
arrays are MEMBERS of the domain. When we wish to manage this environmentwith our UI, we enter the IP Address of one of the storage processors on theMASTER (or any system in the Domain), and it will automatically bring up all thearrays in this Domain. This will be discussed and configured in the CLARiiON HostIntegration Workshop.\
Because setting up this network is critical for configuring and managing the arrays,our first order of business with a new array will be to configure its IP addresses.

There are two topologies supported for the Navisphere Management User Interface(ManagementUI). One is called On Array. You can install, via NDU, the UIsdirectly onto an array. When a supported client browser, running the proper versionof Java, enters the IP address of an array which has ON-ARRAY UI installed, the UIwill be pushed into the browser/java session and then open communication with theManagement Server running on that array.
The other option is to directly install the Windows-based version directly onto theManagement Station. This allows you to directly manage all arrays regardless ofwhether they have the ON-ARRAY installed. Arrays ship by default without the UI,since this is a revenue item.
