Re: It's hilarious
So you now refute to name calling.. That is nice and mature, but kind of shows your true colours.
I am fully aware of what Oracle SPARC SuperCluster is made up of. I get bombarded with Business Partner information all the time, and invitations and presentations and and and...
And where as I really Really really like the Oracle Database, and I have a profound respect for the SUN systems of old days, where I (and also on hp9000) as an young computer science major learned the craft of *NIXing, I have no problem calling a pig with lipstick for what it is.. a pig.
As for benchmarks, then basically the only industry benchmarks where the T4's have really gone against other systems are TPC-H and SPECjEnterprise2010.
Now TPC-H is there cause Oracle cracked that benchmark some years ago, and even the OLD M9000 systems were able to beat other systems that they normally wouldn't have a chance against in other benchmarks.
SPECjEnterprise2010, cause that it what the T-processors were really designed for with their many threads and hardware accelerators, and they also threw a lot of 'auxiliary' hardware at the benchmark also, as price isn't a factor. But the accelerators is really what makes the machines shine, cause they do that, in this benchmark. Just to bad for Oracle that POWER7+ will now have the same type of accelerators, so lets see what happens then.
But that is basically it, there aren't really any other datapoints, besides the prelaunch comparisions to the T3, and they really don't support your claims.
Now as for price.. then sure a comparison is a good idea.
What you don't seem to get Phil, is the magicians move that oracle is doing.. waving one hand to catch your attention while putting the other one deep into your pocket. Oracle will give you the the damn hardware for free, if you buy their bloody software.
Now the list price of a brand spanking new POWER 770 with POWERVM and AIX in enterprise edition Hypervisor mirroring, Memory compression bla bla. will set you back 2MUSD in list price including 3 years worth of HW maintenance etc etc.
Now a full rack SuperCluser will set you back ~1.8-1.9MUSD, with 3 years of support.
Now surely the POWER 770 does not include storage.. which it should.. so .. lets.. nahh ... lets just look at the software.cost, we can always put in a few SDD disks later. (they are real cheap)
Now the SuperCluster needs some software licenses, if you will run Oracle on it.
You'll need Oracle EE, Oracle RAC, Oracle Partitioning, with 3 years of swma, for the SuperCluster and only Oracle EE for the POWER 770, if you need to run the full Oracle monty.
Now that is 8.711.680 USD for the Oracle Supercluster versus 5.046.400 USD for the POWER machine
Which basically gives you 2.5 Million USD to buy some storage for the POWER 770. And surely I could go with the 48 core 6 cores per chip POWER 770 rather than the 64 core version, cutting away 25% of the Oracle prices.. while only loosing around 10% in throughput and no memory.
If you compare the RAS features on the machines, you'll find on the T4-4 specs looking like this:
Hot-pluggable disk drives
Redundant, hot-swappable power supplies and fans
Extended ECC, error correction and parity checking memor
Easy component replacement
Integrated disk controller with RAID 0 and 1
Compared to the POWER 770 (or the SD2 for that matter) It's pathetic.
A machine like the POWER 770 will do:
Redundant hotswap powersupply, fans and adapters.
Concurrent firmware updates.
Processor instruction retry
Alternate processor retry of instructions.
Live Partition Mobility and Live Application Mobility.
Redundant service processor and system clock with hot failover of both.
Hot node repair.
Mirrored Hypervisor memory.
Again.. the T4-4 won't even hot-swap an adapter .. you have to take that whole server down. You basically need a n+1 configuration that you won't need with the POWER 770 or a SD2 or a M9000.
So what would normally be something that is a standard simple change, all of a sudden becomes a more complex issue with the Supercluster.
Again that is what all the Infiniband and storage nodes and and is all about, addressing the shortcomings of a cluster with added hardware components and complexity. And downtime and service windows.. cost a LOT of money.. again.. TCO.
A machine like the POWER 770 will do memory compression, out of the box, for the Supercluster it's 11.5KUSD per license + 22% in yearly swma. Which will set you back 1.2 MUSD on 4 node cluster machine. Sure DB compression is better than compression in HW or on OS level... but 1.2 MUSD ? brrrr..
A machine like the POWER 770 has shared pool processor virtualization (so does the SD2), where as on a T4-4 server you'll have to turn to both Zones and LDoms for some of the same functionality. Which basically means that it'll run with a good deal better utilization in a RL virtualized environment, as you will basically be forced to do partitioning in a multi tenant environment, on a T4.
I always get amazed when what is basically v-par/LPAR in HP/IBM terms is touted as virtualization.
A machine like the POWER 770 also does infiniband, actually the x12 adapter plugs directly into a GX++ mezanine bus. No need to fight with other adapters over the bandwidth to the processor. And with this being a single system, there isn't even the need for an infiniband switch to get involved.. it can just be a tube directly to a sh*tload of SDD drives.
And what is better than about 12TB of SDD storage directly in an IO drawer and then virtualized through the Hypervisor, for maximum IO speed ? Wroom Wroom.
You do know the SPC-1 benchmark where an old POWER6 machine(that is 2007 technology with PCI-X ) beats out a pair of Oracle Sun ZFS Storage 7420c Appliance, by a factor of 2+.. with half the latency...and ?
It's like.. why setup a compex storage setup with infiniband and storage servers and bits and bolts that break and needs firmware updates and and and and when you can achieve the same in software inside a single high RAS machine ?
Then there is the Datacenter cost picture. A T4-4 uses a massive 2.7 KW when 100% active compared to the 4.5KW of the POWER 770 (both number using Oracle and IBM power/heat calculators), that is double the heat density for the T4, so much for coolthreads. Furthermore the max operating temperature of a Supercluster is 32C versus 35C for the POWER 770. This basically means that you need to be able to handle a heat density that is almost twice as dense with at T4 than you need with a POWER 770. And a SuperCLuster rack uses 15KW max power.
It does require a rather modern datacenter, which.. costs a lot of money.. Again .. tco...tco...
Well.. I could keep going.. ... but.. I'll let Matt handle the SD2 vs SuperCluster, he's most likely better skilled to do that than I am.
... and try to cut down on the Snoracle Cool aid Phil :)=
