175.0. "Cluster Configuration Changes" by ELBOW::DRAPER (Steve Draper) Thu Sep 15 1988 09:56

    In a recent note (174.4 written 13-Sep-88), I said that I would soon be
    giving details of forthcoming hardware (and software) moves - so here
    they are. 
    
    The changes will occur in several stages in order to minimise the
    impact on ADG, and are designed to try and meet the following
    objectives:
    
    1.	To increase the power in the Order Fulfilment Integration Cluster.
    	This currently consists of 2 x 11/785 for which 2 x 8700
	replacements had been ordered. These 8700s have now been cancelled
    	and we must do what we can with the equipment we currently have.
    
    2.	To make more efficient use of our processors.
    
    3.	To eliminate the use of the RDGEnn series node names. The intention
    	to do this was announced back in May, prior to our move to The
    	Crescent - at last its now going to happen!
    
    4.	To make more efficient use of our disk space.
    
    First, for the benefit of those who have recently joined us and
    are not sure of the configurations that we currently operate, I
    will describe them briefly:
    
    	CLUSTER		NODE	TYPE		USAGE
    	-------		----	----		-----
    
    	SUPPRT		VULCAN	8250		Support of all released
    			HEAD	8530		software
    
    	ADG		FOOT	8530		Development of software
    			RDGE00	11/785		on the version of VMS
    			RDGE28	11/785		currently used by I.S.
    						Operations.
    
    	FUTURS		CHEST	8530		Development of software
    			RDGE43	11/785		on the next version
    						of VMS to be used by
    						I.S. Operations.
    
    	<standalone>	STOPIT	8700		End User Engineering
    						system
    
    In addition to the above, there is an Order Fulfilment Integration
    cluster which currently consists of 2 x 11/785s. The purpose of
    this cluster is for integration testing of the component products
    of Order Fulfilment. No development or support work is done on this
    cluster.
    
    None of the HARDWARE moves described in this note will affect the
    SUPPRT cluster.
    
    The table below shows the machine moves that will take place,
    using the existing node names as an aid to clarity:
    
    	CLUSTER		NODE	TYPE
    	-------		----	----
    
    	ADG		STOPIT	8700
    			RDGE28	11/785
    			URIAH	11/785
    			HEEP	11/785
    
    	FUTURS		CHEST	8530
    			RDGE00	11/785
    			RDGE43	11/785
    
    	O.F.		FLAT	8700*
    	INTEGRATION	FOOT	8530
    
    		* System on loan from I.S. Computer Resources.
    
    Using the new node names, the clusters will appear as shown below:
    
    	CLUSTER		NODE	TYPE
    	-------		----	----
    
    	ADG		FOOT	8700
    			INCH	11/785^
    			YARD	11/785
    			MILE	11/785
    
    	FUTURS		CHEST	8530
    			CRATE	11/785^
    			COFFIN	11/785^
    
    	O.F.		URIAH	8530
    	INTEGRATION	HEEP	8700
    
    		^System due to be upgraded to 8700 (delivery scheduled
    		 for October/November 1988)
    
    The schedule for these changes is currently as follows:
    
    i)		New 8700 installation (ex FLAT) starts Mon 19th Sept.
    
    ii)		New 8700 replaces 8530 (FOOT) in ADG cluster Sat 24th Sept.
    
    iii)	8530 (FOOT) replaces 11/785 (URIAH) in O.F. cluster
    		Sat 24th Sept.
    
    iv)		11/785 (URIAH) boots into ADG cluster on new root
    		Sat 24th Sept.
    
    v)		8700 (STOPIT) workload moves to ADG cluster on or by
    		Sat 1st Oct.
    
    vi)		8700 (STOPIT) replaces 11/785 (HEEP) in O.F. cluster
    		Sat 1st Oct.
    
    vii)	11/785 (HEEP) boots in FUTURS cluster on new root
    		Sat 1st Oct.
    
    As each new or moved processor joins a cluster its node name will
    be changed to remove the Reading node names (RDGEnn). The Reading
    node names associated with PDP systems (RDGE03, RDGE39) will be
    dealt with separately.

    Objective 4 (to make more efficient use of our disk space) is being
    dealt with by a separate, but parallel exercise to ensure that all
    projects are on the correct cluster (SUPPRT/ADG/FUTURS) or
    alternatively either archived or deleted. This project is being
    run by our Sandwich Student (Steve Green) under the direction of
    Jerry Thompson. Steve G. is currently compiling a list of all projects
    and the people responsible for them, and will be in touch with those
    people in the near future. A possible spin-off from this exercise
    that is currently under consideration is the creation of a project
    database and associated software/proceedures to try to ensure that
    we keep on top of this situation in the future.

175.1Wot, no software changes?FOOT::RUSSELLSpeak softly, and carry a beagle.Thu Sep 15 1988 14:478
    Ummm, sounds good(-ish), Steve.
    
    But, what about the VMS V5 updgrades?
    
    Wot's 'appening about that, then, eh?
    
    Peter.
    
175.2More info on the way...FOOT::CAITHNESSColin CAITHNESS, @UCG, 781-4335Mon Sep 19 1988 15:564
I'm attending a meeting tomorrow to finalise the software upgrades, I'll let
you know ASAP.

Colin.
175.3FOOT::RUSSELLLife is short, then you die. (W. Allen)Thu Sep 22 1988 12:3010
    Two things, chaps and chapesses...
    
    a) wot abaht V5, then, eh? Where's the update promised in .2??
    
    b) when will the network node changes be made for the clusters'
    new names, and will it be a *full* network update  - there seem's
    to be quite a lot of systems moving over the pond this weekend...
    
    Peter.
    
175.4EASE and VMS V5.0 coming soon!FOOT::CAITHNESSColin CAITHNESS, @UCG, 781-4335Fri Sep 30 1988 13:4019
Okay, here's a minor update...

FUTURS will be the VMS V5.0 machine (no surprises there!). The plan is to
upgrade FUTURS to V5 and EASE at the same time, as EASE comes pre-built
within the V5 environment. There is no fixed date as yet, except that it
will be within the October/November timeframe. There is a UK IS technical
forum next week to determine the actual dates, so we should know by the
following week.

The VMS V4.7 layered product upgrade will also be going ahead, again in the
October/November timeframe. And once again, firm dates for the upgrades will
be determined at next weeks forum. These layered product upgrades will not
effect any applications based at The Crescent, as the recent questionnaire
showed.

That's all for now, more information soon (around 10th-12th October).

Colin.
175.5SUPPRT cluster hardware changesNECK::THOMPSONMon Oct 03 1988 13:5531
        
	Glad tiding peeps - the SUPPRT cluster will shortly (in the next
	month-ish) be getting its NEW disc drives installed.

	The changes will be

PRESENT SUPPRT DEVICES			NEW SUPPRT DEVICES
$21$DUA0:	RA81	Systemdisk	RA81 (No size change, but now shadowed)
$21$DUS1:	RA81	Userdisk	RA82 (Shadowable)
$21$DUS2:	RA81	Userdisk	RA82 (Shadowable)
$21$DUS5:	RA81	Userdisk	RA82 (Shadowable)
$21$DUS10:	RA81	Userdisk	RA82 (Shadowable)
none					RA82 (Floating Shadow volume)
none					RA82 (Floating Shadow volume)
$21$DJA4 	RA60	Userdisk	NO replacement

	Which will mean 

	1)There will be enough space (just) to load all
	applications supported from the Crescent on the
	Support cluster i.e. move all supported environments
    	off ADG and FUTURS clusters.

	2)It will be possible to keep the cluster running
	24 hours a day, 7 days a week with NO SHUTDOWN FOR
	BACKUPS. 

	Watch the login notices for more news.
