Tape SAN Help
by Ambrose_Earle＠shamrockfoods.com 21 Aug '01

21 Aug '01

We are having enormous problems configuring our new tape libraries with our filers. We keep getting different answers from people and I hope that someone on this list has something similar in production and they would be willing to share their information. Here's what we hope to have running: 2 F840c's 1 Brocade 2400 2 internal fibre channel bridges inside an Overland Data library a few other servers on the switch NetVault with dynamic drive sharing option So, should everything be fabric, do we need to zone, any other ideas? Thanks for your time,

Solaris/Oracle/filer tuning question
by Chris Lamb 21 Aug '01

21 Aug '01

Howdy, all. This is more a Solaris question, but since there's a filer involved and y'all are so helpful, I'll start with you guys. :-) The setup: Sun E4500, Solaris 7 HW11/99+patches, GigE NetApp F760, 5.3.6R2, GigE Oracle 8.1.6.x Two volumes for Oracle, NFSv3/UDP, 32K rsize/wsize The problem(s): I/O from any single Oracle process tops out around 3-4MB/sec; Even with 'disk_asynch_io = false' in init.ora set to false, we are getting sporadic and seemingly nonsensical "resource temporarily unavailable" errors (had a case open for this one). The question: Are any of the Solaris kernel NFS tunables useful in increasing that apparent limit? Specifically: nfs:nfs3_max_threads nfs:nfs3_async_clusters nfs:nfs3_nra The DBA and our NetApp reps/support team have gone over our config, and things are generally stable. After turning off asynch_io we noticed a slight performance hit, but thought that the annoying "resource temporarily unavailable" errors had been solved. We had another one yesterday, first time in almost two months. :-/ In diagnosing the performance sluggishness, we noticed that for a non-partitioned full table scan a single Oracle "reader" process was limited to about 2.5-4MB/sec, while a full scan of a partitioned table (using 6 readers) was getting 18-22MB/sec. (Obvious workaround: increase the number of readers and writers, and partition the table with the bottleneck...) In each case, Solaris iostat was claiming that the NFS mount was "100% busy", although response times were generally in the sub-6ms range and the filer's sysstat showed less than 20% cpu usage (this is a production box, so I can't completely isolate the load for our testing). For _reads_ I just can't figure out why Solaris - or Oracle itself - are throttling performance like this... I've clocked > 50MB/sec reads in plain old NFS tests (bonnie, cpio, etc), and I think it's generally clear when we've saturated the PCI bus on the filer. This Oracle bottleneck is a mystery, but now I'm wondering if the two problems are related. The Solaris Tunable Parameters Reference Manual says of the "nfs:nfs3_max_threads" knob: "Controls the number of kernel threads that perform asynchronous I/O for the NFS version 3 _client_. [emphasis mine] Since NFS is based on RPC and RPC is inherently synchronous, separate execution contexts are required to perform NFS operations that are asynchronous from the calling thread." The default pool of threads is set to 8. There's some indication that this may be a _per filesystem_ setting, and is not global to all NFS client activity on the machine. Even if that's the case, then 8 threads per mount point might still be fairly restrictive on an 8-cpu machine, given the fat pipe and headroom still available on the filer. I generally shy away from mucking about with Solaris internals ("this isn't your father's SunOS" :-) but if that's what it takes to boost performance I'm all for it. Has anyone running in a similar environment had to tweak any Solaris kernel tunables? Are there other Oracle/NetApp tuning hints not discussed in the whitepapers on the NOW site? My DBA and I would be most grateful for any warnings/suggestions/hints. :-) I'll be happy to provide more detail off-list, then summarize results if anyone else is interested.

RE: DOT 6.1.1 + NBU 4.6 == /vol/vol0 path may not exist
by Smith, A Michael (CS) 20 Aug '01

20 Aug '01

Is /vol/vol0 on your machine a snapmirror destination? If so try backing up an existing snapshot as ndmpd will not be able to create a snapshot for dump on a snapmirrored volume. The path that I use in the Backup Policy Mgmt interface under the policy of my choice I simply change the entry from "/vol/vol2" to "/vol/vol2/.snapshot/hourly.0" and bada-bing it worked. If it is not snapmirrored then another test to try would be to run a manual dump of /vol/vol0 and send the output to null: dump 0f null /vol/vol0 The output of that command will be useful for NetApp support folks.

Benchmarks
by Joe Luchtenberg 20 Aug '01

20 Aug '01

SPEC pulled the benchmark (SPECsfs97) that NetApp has used for so long as the yardstick for their screaming performance (see http://www.spec.org/osg/sfs97/sfs97_notice.html). As far as I can tell, there is no replacement from SPEC. Curiosity question: Do any of you out there in toasterland use published benchmark statistics in order to at least narrow the field when considering future storage options? If so, how does this development effect you? Joe Luchtenberg Dataline, Inc. 757-858-0600 757-285-1223 (mobile) 757-858-0606 (fax) joe.luchtenberg(a)data-line.com www.data-line.com

You can do: snap create before_delete delete files snap delete before_delete But this will not bring you into any better situation than the beginning one... Usually I view it like a cake - you cannot eat it and expect it to be still complete - if you want to be able to restore files you will have to keep the snapshot.
