We have been asked to respond to an RFP for a data center cluster that will be used solely for NFS services. The client environment is mostly SUN workstations, about 150. They are all connected via 10BaseT although the customer is in the process of migrating to 100BaseT, and the servers in the data center are on 100BaseT switches. The initial size of the NFS area will be 120GB growing to 300GB. The access profile (reads vs writes, I/O's vs bandwidth) is not clear - according to the customer no one dominant access tendency. I am looking for any competitive advantages that I can flaunt over Sun (who is the incumbent and competiton for this RFP). I have some data but I welcome any and all comments, suggestions, gotchas to watch out for, etc. Anyone who has responded to such a request that can share their solution and how you won would help. What are our advantages given we will be serving Sun workstations running mostly Solaris (I believe - I am awaiting an answer on that one but its a safe assumption)? Do we have many or is this going to be just a price war? I am flaunting our StorageWorks advantages, I need some UNIX ammo. Thanks, -BAP

| 8826.1 | LADDIS? | NQOS01::mko-ras-port-6.mko.dec.com::Pellerin | Fri Feb 14 1997 12:30 | 12 | |
Initial searches that I've done to see where we stack up on LADDIS have shown that Sun is the predominant player here. I got my infr from the Ideas International page which posts most up to date benchmarks. Do we have any LADDIS benchmarks? Where are they? Since we helped to create the benchmark, are we keeping up with the industry here? Coments, suggestions? Regards, -BAP | |||||

Answering my own reply, I just found the results from the SPEC page. Looks like SPEC operates a little differently than TPC, in that quarterly results are posted an not merged with past results. Any info re .0 is still welcome. | |||||

See http://sdtad.zko.dec.com/pub/csdpg/ and look for SPEC SFS pointers. The main one you'll find is SPEC's page http://www.specbench.org/osg/sfs/results/ One problem we have with Solaris is that Sun wants to do I/O 32 KB at a time. We still only do 8KB, but we're fixing the server for Steel. The way Sun deals with us results in writing the 1st 8KB of several 32KB pieces, then the 2nd 8KB, etc. This bamboozles AdvFS's allocation, but apparently that will be fixed in Steel too. Sun has much better LADDIS numbers compared to our non-cluster systems, but we should be working on that too. In the mid range, Rawhides and Durangos could be really, really good machines. CSD is doing SFS runs now, and is at 6000 ops/sec or so with CPU time left over. (6000 is about the limit for 2 FDDI loops, which is what they're running, soon to be increased to 3 loops.)
