New terms and architectural concepts

New Terms and Architectural Concepts


New terms

New Terms

  • IMA: Independent Management Architecture

  • Data Store: Central configuration database

  • LHC: Local Host Cache. Persistent data cache that exists on each server.

  • Data Collector: Manages dynamic data and client enumeration/resolution (replaces ICA Master Browser).

  • Zone: Deliberate grouping of XP servers, each with it’s own Data Collector.

  • CMC: Citrix Management Console (replaces MF 1.8 administration tools).


What is ima why is it important

What is IMA? Why is it important?

IMA…

  • Is a TCP based, event driven messaging bus, used by MetaFrame servers and management tools communication.

  • Is a modular and easily extensible subsystem capable of supporting current and future MetaFrame products and tools.

  • Overcomes the scalability constraints of the MetaFrame 1.8 Platform, allowing us to scale environments to new levels.

  • Allows us to administer any farm from a central tool (CMC) that doesn’t have to run on a MetaFrame server.

  • Will allow Citrix to add functionality to the Platform independent of the base server.

Metaframe server farms

MetaFrame Server Farms

  • MetaFrame 1.8:

  • Server Farms in MetaFrame 1.8 are a collection of servers on a given broadcast segment that are be managed as a single unit.

  • Server Farms in MetaFrame 1.8 may also be defined by sharing a common ‘Application Set’.

  • MetaFrame XP:

  • The Server Farm in MetaFrame XP defines the scope of management as well as the ‘Application Set’.

  • Server Farms in MetaFrame XP are designed to operate across segments, and are managed through the Citrix Management Console.

Data Store

Attributes of the MetaFrame XP Data Store (DS)

  • The DS is a repository (database) which contains persistent, farm wide data like member servers, licenses in farm, zone configs, printers/drivers, published apps, load evaluators, trust relationships, etc.

  • Each MetaFrame XP farm shares one Data Store.

  • All information in the DS is stored in an encrypted binary format (except indexes).

  • A Farm can operate for 48 hours if DS is unavailable, then licenses time out and no new users can connect.

  • A DS can be an Access, MS SQL, or Oracle database.

  • A DS can be configured for either ‘Direct’ or ‘Indirect’ access.


Data store in direct mode

Data Store in ‘Direct’ Mode

DS

Attributes of Direct Mode

Communication Events

  • Farm modification through CMC

    • Modifications happen through a 2 phase process:

    • 1: CMC (through a MetaFrame server) commits the change to the DS.

    • 2: CMC/IMA packages and distributes changes <10k to the DC’s, who then distribute it to member servers. If the change is >10k, it distributes a change notification and servers perform consistency check on LHC.

    • If member servers are unavailable, they receive the change during the periodic LHC consistency check.

Print management recommendations

Print Management Recommendations

  • Print drivers can only be replicated to the servers of the same OS as the source server.

  • Install drivers on the source server and select any available port on the server.

  • If installing for the sole purpose of replication there is no need to share the printers or set them as default.

  • Can be very CPU intensive on the source server so avoid replicating drivers while the source server has a heavy load.


Printer queue management

Printer Queue Management

  • #QueueEntries = [#Drivers] * [#Servers]

    • Every driver/server combination creates a queue item in the printer replication queue.

    • Should not exceed 1500 entries in length

    • Eg. 30 drivers to 50 servers

  • QPRINTER Utility

    • Not installed by default.

    • \support\debug\i386

    • QPRINTER /REPLICA

Mixed mode

Mixed Mode

Until you get to native mode, you can’t take full advantage of:

  • Increased farm scalability and stability

  • Advanced printer management

  • UPN support

  • Simplified license management and activation

    • 1.8 license gateways are not supported

    • MetaFrame connection licenses are equally distributed among subnets

    • CMC/Farm/Properties/Interoperability can change licenses assigned to each subnet.


Mixed mode cont

Mixed Mode (Cont.)

On first XP install, if 1.8 is detected on the segment, it will offer to run in mixed mode

  • If yes, legacy tools are automatically installed

    Admins must use two sets of tools to manage a mixed farm

  • appcfg shipped on XP is same as 1.8 sp2. Older versions may not be able to manage apps published with newer versions.

    Apps may be published on 1.8, then XP. Not the reverse


Migration strategies

Migration Strategies


Migration strategies flash upgrade

Migration Strategies – Flash Upgrade

  • All servers are upgraded to Extended Platform during scheduled network maintenance window

    • Consider this for highly centralized and/or cloned server environments

    • Citrix now supports both unattended and cloned installs for all but the first server in an XP farm. See specific documentation in Admin Guide.

      Note: Repeated licenses will give an error upon migration to IMA Data Store.


Migration strategies parallel

Migration Strategies – Parallel

  • XP servers built in native mode

  • 1.8 and XP servers do not communicate w/ each other

  • Consider this for fast growing installs, new Win2K rollouts, or multi-site scenarios

    • Requires additional hardware and licenses.

    • Alternately, users may be manually migrated in proportion to servers.

    • XP apps are published manually rather than migrated

    • Publish 1.8 and XP apps to distinct user groups to prevent redundant icons


Migration strategies mixed mode

Migration Strategies – Mixed Mode

  • Rolling upgrade of existing MetaFrame servers

    • Set during install of first server in the farm

    • XP and 1.8 farm names must match

    • XP server will win ICA browser election

      • (except 1.8 sp1 MB hardcode)

    • Mixed mode applies to all XP servers in the farm

    • Starts PN and ICA browser services on XP servers.

    • Existing apps are migrated to IMA data store (1 time)

      • Any appcfg. changes made to 1.8 apps after migration are not updated to the data store


Using nfuse to bridge the gap

Using NFuse to Bridge the Gap


Nfuse as a bridging technology

NFuse as a Bridging Technology

  • NFuse allows administrators to hide complexity from the end user. For migration, it can be used to present applications from an arbitrary number of farms

    • MetaFrame 1.8

    • MetaFrame Extended Platform

    • MetaFrame for UNIX

    • Multiple sites

Migration scenarios

Migration Scenarios


Scenario 1 single site single farm migration

Scenario 1: Single Site Single Farm Migration

  • High level steps (‘rolling’ upgrade):

    • Create IMA DataStore if necessary

    • Upgrade a server besides the ICA master browser

      • Install in interoperability mode when prompted

      • Apply upgrade licenses to XP farm

    • Upgrade remaining servers

    • Switch to XP native mode

    • Enable/disable UDP browsing as needed


Scenario 1 single site single farm migration1

Scenario 1: Single Site Single Farm Migration

  • Single Farm Migration Tips:

    • Avoid publishing new apps or changing app configuration while in XP interoperability mode. If necessary, create/modify apps in 1.8 first then XP.

    • Use NFuse and/or auto-client update to distribute new ICA clients.


Scenario 2 multi farm consolidation

Scenario 2: Multi-Farm Consolidation

  • High level steps:

    • Ensure IMA server to server communication (default TCP 2512)

    • Upgrade first farm (including switch to native mode) or build new Enterprise XP farm (in native mode)

    • Perform upgrades of other 1.8 servers (one farm at a time) joining them to the ‘Master’ XP farm

    • Some manual cleanup of duplicate app names may be necessary.


Scenario 2 multi farm consolidation1

Scenario 2: Multi-Farm Consolidation

  • Multi-Farm consolidation tips:

    • Key: managing user connectivity.

      • If possible, use an NFuse portal pointing to multiple farms. NFuse can play a HUGE role here!

      • If using PN, add/change Application Set objects and server location/browser type.

      • If using single published app, may need to modify server location/browser type.

      • If using ICA file(s), may need to modify server location/browser type.

    • Use NFuse and/or auto-client update to distribute new clients.
