Re: z890 power: 3 phase vs 1 phase?
The main difference between single phase and 3-phase (basicallya ground and 2 live circuits)is the resultant voltage.

Re: z890 power: 3 phase vs 1 phase?
2 Live + ground is two phase. A three phase supplies doesn't need a ground, but usually one is provided to allow single phase equipment to be used. Power is generated by three phase alternators and these expect the load on each phase to be identical. So in most areas of buildings where high power is used (e.g. a large machine room or server centre) there will be outlets connected to each of the three phases and attempts made to balance the load across the phases. Certainly in the UK using the power in an unbalanced way may result in financial penalties. Typically three phase equipment performs the balancing internally so are desirable from the suppliers point of view. Even when we ran 4381's we still had a mix of three phase and single phase, but of course we are on 22volts. I don't think there is any three phase stuff left in our machine room any more.

Re: z890 power: 3 phase vs 1 phase?
Lots of discussion on this.. I'm no expert, but it didn't sound right. I found 2 relevant articles on Wikipedia: http://en.wikipedia.org/wiki/Three-phase_electric_power http://en.wikipedia.org/wiki/Split_phase So, your dryer, oven, etc. in a U.S. home runs on split phase power, *not* 3 phase. (2 phase power is not the same as split phase.) And your reference to ground should be neutral. The ground wire should never carry a current - if it does, then you have a problem. It is there for safety. The neutral wire (I've heard it called the grounded conductor) can carry current for loads that require a single phase. I agree with what you said about 3 phase in commercial installations. Note: My experience is only the U.S.A. - what you say may be true for the U.K. On Mon, May 4, 2009 at 12:52 PM, Dave Wade g4...@dpwade.eclipse.co.uk wrote: 2 Live + ground is two phase.

You get faster backups if you can keep the drive going. An IBM 3590E writes to tape at 14 MBs. If hardware compression is turned on and you are getting 3:1 compression, then you have to feed the controller at 3*14 or 42 MBs. If you can, you have the best of both worlds, speed and amount of data on a single tape. If you can't then you need to choose speed vs high data storage. We have no problems feeding the beast. We are writing to a remote SL3000 across the wire, a high speed wire to be sure, but one that is shared by other systems doing similar things. The network people have determined that our workload will not strain the capacity, and they appear to be correct. A backup of our larger VTAPE (VSSI version) library takes between 2.5 and 3 hours when the output is to local tape drives (Ficon connected) and only a few minutes more, less than 15, when writing to the remote site which is 1500 miles away. Doing software compression, only makes sense to me if you are going over slow (escon) channels. Given all that In DR tests, less tapes seems to be a good thing. With the current high-capacity, high-speed drives, the number of tapes is well under control. The VTAPE library backup mentioned above requires only a single tape to back a 26 (3390-03) volume library that typically runs 80% or more occupancy. The DR site has better, faster, hardware then most of our shops. (everything is ficon) You may buy less MIPS but you can't buy less I/O thruput. It takes more CPU to compress data then it takes to expand the data. i.e. worry about your own MIPS. We have the same kind of h/w as the DR site. It is an LPAR carved out of a system at our second continental datacenter. We may on occasion, for a short while, have better equipment than it. The prudent path is usually to install the new hardware on the VM development system before implementing it on the production systems. We get the devices and processors before that are deemed acceptable as replacements for the hardware used by TPF. In general, I don't see the benefit in software compression, when hardware compression is available. But if you tested the difference in your site, and you have come to a software compression conclusion, more power to you. Each site has a different set of concerns. The original question had as much to do with is there anything to be gained using both types of compression because the defaults for both Hidro and the tape drives is to compress the data or, if not, which was likely to be better at doing the compression. It would appear that h/w alone is the answer. That is, it is if the SL3000 does the compaction prior to sending the data across the wire. Tom Duerbusch THD Consulting Alain Benveniste a.benveni...@free.fr 4/30/2009 6:25 AM Richard, You have the same questions I had when I started to put in place our DR solution. We also have 3590E drives and I never tried to remove the hard drive default compaction. I don¹t see a reason for that. Now choosing software compaction is a must if you have enough cpu to do the work for backup and ALSO for restore. For us we can spend more time to use software compaction because we know that we have enough cpu to do the work at restore time offsite. The gain at restore justifies to take more time at backup processing. It¹s true too that software compaction takes less tapes than with no compaction. If you have many dasds to backup and a time constraint to restore i would suggest you to both use hard and software compactions. Our idea is to say that when we restore in a DR test the cpu is used ONLY for restore. Why not fully using it ! Regards Alain Benveniste Le 29/04/09 20:46, « Schuh, Richard » rsc...@visa.com a écrit : We are working on a DR process. I notice that the defaults for a Hidro backup include the PACK option which tells Hidro to pack, or condense in some fashion, its output. The output is being written to 3590E drives. It appears that there are three choices we can make for condensing the data: software only, hardware only, or a combination of the two (uncompacted was purposely omitted from the list). Which is likely to give the best results? Does software compaction produce consistently lower output volumes than letting the drive do it? Is there anything to be gained by using both h/w and s/w? Obviously, software compaction costs in terms of cpu time. The question is, is it worth the time spent? Regards, Richard Schuh
Re: Third level VSE
He did initially point everyone to the VM overhead in a VM/VM/VSE system, but I also wonder about other items. They got a bigger processor, but is it the same number of engines? A uni to a larger dual processor (he talked about number of engines on the z890), is a lot of heart burn. VSE/ESA 2.3 doesn't have the Turbo dispatcher on by default. So, only one engine is used. But when you turn on Turbo dispatcher, then you also have additional overhead (per the foils). I do wonder if the second level VM and the third level VSE have all processors available to then (with turbo dispatch on)? When they have performance problems and you don't have a good performance monitor, my stance is, if IND doesn't show 95% or more CPU utilization, you don't have a CPU problem. A bad T/V ratio, is all about the CPU. Of course, unless real performance numbers are posted, this discussion is just bar talk G.

Re: Packing Methods
Ok so you can feed the beast, when running software and hardware compression. Good. The software compression is able to read/compress/send down the channel at a rate of 14 MBs. The hardware compression isn't going to do much. Normally, compressing a compressed file makes the file grow slightly. So the 14 MBs keeps the tape moving. You might be able to send data down a little faster until the tape controller is full, then you will be throttled down to native tape drive speed. If you turned off software compression, then you need to send to the drive at a rate near 42 MBs (3:1 compression) in order to keep the tape moving. That may or may not be doable at your shop, with your current hardware. You're ficon, which can do it, but I've never experienced distance communication at or near the rated speed. Always less. How much less and does it make a difference? 14 MBs is about 112 mbs. 42 MBs is 336 mbs. And how many transmissions are happening over that line at the same time? All factors feed into keeping the tape heads spinning. I would still test turning off software compression and see what you get. Buying back mainframe CPU cycles is normally a good thing. But if they would just go to waste anyway, and software compression is the only thing that can keep the drive going, then that is a good use of mainframe cycles. However, leaving on hardware compression, really doesn't have much of a cost. If you later add in encryption, the rule to follow is to compress first then encrypt. If you encrypt first, you will have a much larger file as compression will have no effect. We were specing out SAN attached IBM 3592 tape drives. Couldn't be done within budget as most of the network was 1 gb switches, and the 3592, to be driven, needed 2 gb switch (to operate one drive) and 4 gb switch to operate both drives. The SAN disk space, which is fairly old, needed to be upgraded to support the higher transfer rate. (Basically, cheaper to replace the SAN, but no budget for that.)

You get faster backups if you can keep the drive going. An IBM 3590E writes to tape at 14 MBs. If hardware compression is turned on and you are getting 3:1 compression, then you have to feed the controller at 3*14 or 42 MBs. If you can, you have the best of both worlds, speed and amount of data on a single tape. If you can't then you need to choose speed vs high data storage. We have no problems feeding the beast. We are writing to a remote SL3000 across the wire, a high speed wire to be sure, but one that is shared by other systems doing similar things. The network people have determined that our workload will not strain the capacity, and they appear to be correct. A backup of our larger VTAPE (VSSI version) library takes between 2.5 and 3 hours when the output is to local tape drives (Ficon connected) and only a few minutes more, less than 15, when writing to the remote site which is 1500 miles away. Doing software compression, only makes sense to me if you are going over slow (escon) channels. Given all that In DR tests, less tapes seems to be a good thing. With the current high-capacity, high-speed drives, the number of tapes is well under control. The VTAPE library backup mentioned above requires only a single tape to back a 26 (3390-03) volume library that typically runs 80% or more occupancy. The DR site has better, faster, hardware then most of our shops. (everything is ficon) You may buy less MIPS but you can't buy less I/O thruput. It takes more CPU to compress data then it takes to expand the data. i.e. worry about your own MIPS. We have the same kind of h/w as the DR site. It is an LPAR carved out of a system at our second continental datacenter. We may on occasion, for a short while, have better equipment than it. The prudent path is usually to install the new hardware on the VM development system before implementing it on the production systems. We get the devices and processors before that are deemed acceptable as replacements for the hardware used by TPF. In general, I don't see the benefit in software compression, when hardware compression is available. But if you tested the difference in your site, and you have come to a software compression conclusion, more power to you. Each site has a different set of concerns. The original question had as much to do with is there anything to be gained using both types of compression because the defaults for both Hidro and the tape drives is to compress the data or, if not, which was likely to be
Re: z890 power: 3 phase vs 1 phase?
You are perfectly right: the same here in Belgium: neutral is the middle of the 380 3ph, it should never be grounded; 1 ph + neutral gives 240V (used to be 220V 30 years ago).

Re: z890 power: 3 phase vs 1 phase?
Whilst as a consumer you should never connect Protective Ground and Neutral in the UK supply chain this is common. So whilst we have separate ground/earth and neutral wires in the house wiring and in the wall sockets etc. in many new supply systems we also have Protective Multiple Earthing which means that a single conductor in the supply line from substation to premises serves as both Earth and Neutral, and the internal earth and neutral are both connected to this on entry to the house. In these systems it is important not to separately connect the internal Earth or Ground to the real ground, and to ensure that all exposed metal work in the premises is earth bonded. This can cause Radio Hams like myself real problems as you can' put a separate earth on a radio transmitter.

The loss of an input phase is detected and the total input current is switched to the remaining phase pair without any power interruption. Depending on the configuration input power draw, the system can run from several minutes to indefinitely in this condition.

I don't even know which of the machines, HIDRO, SYBMON or my SVM, is the subject of the message. I searched all of the Hidro manuals and used Google looking for either RQS183 or just RQS, to no avail. I even tried the CMS HELP command. Does anyone know (a) the possible causes of the error, and (b) what the real solution of the problem might be? If you know, please share your knowledge; the question is not intended to be a yes or no question. TIA, Richard Schuh
Re: OT: Undocumented from Hidro
ah, ok. I get it. You could open a request and ask Fran or Kitty. I messed around with trying to automate some of it too and luckily didn't have to finish it :) Got z/OS to do those jobs and now XRC.

I don't want to try varying the length of pause several times, only to find out that the answer lies elsewhere.

Marci, sending backup requests to SYBMON is correct for batch runs of multiple volume backup jobs. Richard, that message is from SYBRQST MODULE, part of the HiDRO code that SYBMON runs. Could it be you need to pause a bit before continuing your next step? I do not do multi-job runs via SYBMON, but I am wondering if it is cleaning up or something after the first job wrapped up. -- Jim Vincent
