rp3440 Vs rp4440


Can any one give me short sum of what is major differnece between rp3440 and rp4440 interms of:
1- Perfromance if consider for same application oracle 9i
2- max PROCESSORS speed, MAX RAM, MAX NO OF CPU PER UNIT
4- Price for same configuration.

I know this questions have no thing to do here, but some one may help

1) rp4440 will be better than rp3440
2),3) -- Check the above specs.

Re: rp3440 Vs rp4440

I don't have access to pricing info but I can tell you that the rp3440 can have up to 4 PA8800 processors and the rp4440 can have up to 8 or the same, giving roughly double the performance. The PA8800 can be either 800Mhz or 1.0Ghz. The 3440 can have up to 24GB RAM, while the 4440 can have up to 64GB.

Re: rp3440 Vs rp4440

Therre are LOTS of variables to take into consideration when pricing machines.

You can configure and price machines with the HP Enterprise Configurator:

Re: rp3440 Vs rp4440

In addition to the information above, if you are planning to run a production class oracle database, buy rp4440. We run our development instances only on 3440 series machines. Production machines are 4440s. You can find all other info from the links provided above. Mine is just a real life example.

Also, 4440 series has more PCI expansion slots to add more cards onto it if needed. (2 more than 3440)

Re: rp3440 Vs rp4440

Along these same lines, can someone point me to the differences in I/O banwidwith between a 4440 and N Classes?

I'm looking at replacing some N's with RP4440's....

Re: rp3440 Vs rp4440

Geoff,

The rp4440 has a combined IO peak bandwidth of 4GB/s. This is broken down as follows:

1 x PCI-X 133MHz PCI slot with 1GB/s

1 x PCI-X 133MHz PCI slot with 1GB/s

2 x PCI-X 66MHz PCI slot sharing 0.5GB/s

2 x PCI-X 66MHz PCI slot sharing 0.5GB/s

1 x Core IO (2 x Ultra320 2 x GbE) with 0.5GB/s

1 x MP card and additional IO (USB, DVD drive) with 0.5MB/s

This compares to the N class which had a combined IO peak bandwidth of 6.4GB/s. The N class of course supported up to 12 PCI cards, so needed that extra bandwidth, however even the 'twin-turbo' slots in the N class were only rated at 0.5GB/s each.

So slightly less IO throughput, but more per card on two of the slots (so you can use those dual port or multi-function IO cards). SO if you were doing fast IO (FC or GBE) through more than 8 cards on an N class you might expect not to acheiev the same on a rp4440. As usual your mileage may vary...

Of course although the N class are 'like-for-like' in terms of number of processors, the actual chassis equivalent of the N class is the rp7420, which across the 2 cells and 2 IO cages has an IO peak bandwidth of 15.9GB/s (although its not really a like-for-like comparison in a cell based server).

Re: rp3440 Vs rp4440

the rp3440 has two sockets, so with dual-core PA-8[89]00 that would be four "cores" (what old timers would likely call "CPUs" but of course these wet-behind-the-ears, overeager marketroids often want to call what goes into a single socket a single "processor" - joys of sw licensing I suppose.

anyway, the rp4440 has four sockets and so can have twice the number of cores.

also, while I'm not intimately familiar with the rp's, their rx cousins - the rx26[02]0 and the rx4640 would suggest that the rp4440 can hold much more RAM - max ram on an rx4640 today is 128 GB, max ram on the rx2600 is (IIRC) 24 GB - not sure if the 4GB DIMMS are "supported" in the two socket chassis.

The two socket systems can hold three internal discs. The four socket systems two.

The four socket systems have 8 PCI-X slots of varying speeds across varying numbers of busses - iirc slots 7 and 8 are separate PCI-X 133, slots 3/4 and 5/6 are shared two slot busses, as are (IIRC) slots 1/2. in the two slot chassis there are four PCI-X (IIRC) 133 slots across four PCI-X busses

Re: rp3440 Vs rp4440

Actually, the memory of the rp3440 has recently been expanded to 32GB, with two 4x4GB memory packs. This is true for the rx2620 as well.

1) Because of the greater memory(128 vs 32GB), the theoretical max performance with the rp4440 would be greater, but both units are limited to the same max I/O bandwidth of the zx1 chipset. For a 4 CPU core configuration however, and same memory <=32GB the memory latency of the rp3440 will be slightly less since it doesn't need the memory extender chips.
2) Both have the same processor speeds, but the rp4440 can have 4X the RAM if you get the 32 slot memory carrier or 2X the RAM if you get the 16 slot carrier (memory must be installed in quad using 4 slots per increment). The max number of CPU cores is 4 for the rp3440-4 and 8 for the rp4440-8.
3) The rp4440 is 4U high versus 2U for the rp3440, and it cost more also as it should for larger power supplies, more connectors, I/O slots, etc. Since there will be no more faster pa-risc processors than the pa-8900, unless you think you can move to Itanium to get more performance in the future, it may be lower total cost of ownership over time to get the rp4440 where you can increase performance by adding more memory and CPUs, rather than having to buy a whole new unit.
