PiP: Parity is Pain. Cary Millsap wrote: Here's the sequence of steps I've seen... 1. The salesman who bids RAID5 configuration wins the business, as per Dennis's story. He or she wins because the configuration requires fewer disks than the alternative RAID10 configuration. The salesman gets a nice commission and goes to his company's sales club. 2. Since the system was "sized" for storage capacity (byte counting) instead of I/O rate capacity (I/O-per-second counting), the system runs the risk of failing to keep up with I/O throughput requirements. Especially because RAID5 configurations perform more I/O operations than you think for every Oracle block written by DBWR. 3. If the system has a high enough I/O rate, the company that bought the RAID5 configuration finds out the hard way that the I/O subsystem is severely undersized. The total price of the corrected configuration is more than if the company had bought the RAID10 configuration to begin with. It's a hard deal. BAARF.

Everything else can reside on RAID-5 without a visible performance impact. Second, RAID-5 vendors like EMC and Hitachi usually offer two versions of non-volatile cache: write-through one which essentially performs prefetch and a genuine full cache which caches both read and write calls. The latter type of cache, which is very expensive, is found on Symmetrix boxes only and not on former DG-Clariion boxes (talking EMC here). These types of RAID-5 implementation are usually referred to as RAID-6 or RAID-S. How to benchmark those? Well, the trick in benchmarking those systems is to do what one would never do with it's own system: put redo logs on RAID-5(6,S?), launch several threads of update intensive short transactions (OLTP mix) and count "user commits" from v$sysstat. Prior to that, establish a baseline with RAID 1+0 and see what is the difference. See how many commits would RAID-5 box record during the same time as RAID-1+0 box and you'll know the difference in speed. Also, make sure to pull out one of the disks while system is working and see what's the impact of resilvering. As for the entertainment value, I would hope that Julia Roberts and Mel Gibson would consider making a movie about the RAID-5 conspiracy. Julia would be a DBA trying to purchase a RAID box and Mel Gibson would be a honest RAID-5 salesman which would uncover a nasty EMC, IBM and Hitachi conspiracy. You can tell that it is a fiction because of the phrase "honest RAID salesman". The only problem would be to teach the two of them how not to sound "nucular".

RE: World premier performance of the BAARF party logo
There is no question that RAID 10 performs better than RAID 5. But it highly questionable that every Oracle database requires RAID 10 for all its data files. Though I'd never consider putting redo logs on RAID 5 Also, often the DBA has no clue about what type of disk throughput is needed. Not because the DBA is ignorant, but extracting the information from the potential users which enables the DBA to arrive at an estimate is far too often close to impossible.

RE: World premier performance of the BAARF party logo
Okay, there's a variety of inaccuracies here. 1) "The (full cache), which is very expensive, is found on Symmetrix boxes only" - not true. In fact, just about every storage system today has some sort of protected write-back cache. This is true of hitachi, clariion, symmetrix, netapp, etc. EMC's implementation is a little different than some vendors' because it uses a lot of algorithms to determine where memory pressure exists within the cache and tweaks it accordingly. This can result in both better and worse performance under certain situations - your milage definitely varies in this case. 2) "These(write-back cache types) of RAID-5 implementation are usually referred to as RAID-6 or RAID-S" - I can't speak for what vendors say when they mean RAID-6, but RAID-S has nothing to do with cache strategies. RAID-S is a raid variant that is specific to EMC's strategy on disk layout. Basically, on a normal Symmetrix, you take a physical disk spindle: |---| and split it up into one or more "splits": ||||| and then you protect splits through mirroring them to splits on other disks, etc. With RAID-S you take 4 disks - its always 4 disks, you have no choice in the matter, and split them identically. You then take each positional split across all 4 disks, and one disk of splits becomes the parity and the rest become logical volumes. Sooo, it ends up looking like this: |--P1--|--P2--|--P3--|--P4--| |--D1--|--D4--|--D7--|--D10--| |--D2--|--D5--|--D8--|--D11--| |--D3--|--D6--|--D9--|--D12--| each one of these D-volumes becomes one logical volume that's exposed to the host, so you end up with 12 data volumes exposed to the host. So, its sort of an odd raid-4-ish - there's no striping per se - each split of the disks becomes a logical volume exposed to the host. When a write occurs to D2, let's say, the accompanying data block from D3 and D1 is fetched, and the XOR'ed parity result written to the P1 split. Horrifying? Yes, a little bit - but on non-cache-hungry workloads, it stands up pretty well even on older symmetrixes. On the new Symms, the claim is that RAID-S is just as fast as RAID-1 on everything but the most strenuous workloads - YMMV. There's also RAID-P, which is the exact same critter, only with 8 disks instead of 4. This actually brings up a worthwhile note - on any large-scale array that has "intelligence" in the caching and data management, you have to be very careful as to how you lay your storage out. Poor choice in software stripe size, volume layout, etc. can completely destroy the performance of an array. This can often explain why some people love large-scale array X while others decry its performance. Workload and design, workload and design. Also, the "non-volatile" cache generally means "battery-backed", which while almost as good as true non-volatile RAM, is not the same thing. Batteries die, power supplies get overstressed, and generally terrible things can happen to your storage arrays, and loss-of-power to the cache = loss of data in write-back environments.

RE: World premier performance of the BAARF party logo
Here's the sequence of steps I've seen... 1. The salesman who bids RAID5 configuration wins the business, as per Dennis's story. He or she wins because the configuration requires fewer disks than the alternative RAID10 configuration. The salesman gets a nice commission and goes to his company's sales club. 2. Since the system was "sized" for storage capacity (byte counting) instead of I/O rate capacity (I/O-per-second counting), the system runs the risk of failing to keep up with I/O throughput requirements. Especially because RAID5 configurations perform more I/O operations than you think for every Oracle block written by DBWR. 3. If the system has a high enough I/O rate, the company that bought the RAID5 configuration finds out the hard way that the I/O subsystem is severely undersized. The total price of the corrected configuration is more than if the company had bought the RAID10 configuration to begin with. It's a hard deal. BAARF.

If you always bid RAID5, you will probably receive some business, some commissions, and keep your job. Now, pretend I'm a storage system salesperson. Which system am I going to specify to the customer? Now, if the customer insists on purchasing RAID1+0 or whatever, I'll probably argue a little because I've been stung before where I was suckered into bidding RAID1+0 and then my ignoramus competitor just blindly quoted RAID5 and when it bubbled up to the V.P. he asked "why are you going with the more expensive vendor"? And trying to quote a salesperson isn't a good move at that point. I thought Rachel had a good point on this topic awhile back. If you are a top-notch consultant that is often called in to solve performance problems, you have often cured them by switching from RAID5. So you have a lot of confidence in it. But if you are the lowly on-site DBA just trying to hang onto your job in the political turbulence, you usually don't have enough facts to challenge the system administrators who trust their storage vendors a lot more than a DBA that couldn't actually configure a storage system to save his or her life. So suppose I do try to challenge the system administrators. I say that RAID1+0 will write faster than RAID5. The reply is "okay how much faster?" I mumble that I've never seen any actual figures published anywhere. He or she says maybe at the low level there is a slight advantage to RAID1+0, but with a gig of battery-backed cache that won't be true. Or he or she asks "What does Oracle recommend?". And on it goes. Okay, I'm being provocative here. But how do I, a lowly DBA, prove which is faster? Should I talk my system administrator into going to the trouble of configuring a system both ways and run some tests? What type of tests would be most useful? If I choose the wrong test, and RAID5 looks just as good as RAID1+0, I'm sunk. Then for years to come when I try to make a point at a meeting someone will say "yeah, is this another RAID1+0 theory?"

Re: World premier performance of the BAARF party logo
Dan, Excellent idea. We will of course put your comment into the official BAARF paper version 2 (which I think I can have ready in about 42 seconds from now) as an important (and so far the only) footnote. What I like about your idea is that it got me wondering if the future has already started? I mean, I have seen RAID-40 sold (albeit under the name RAID-50), and I have seen RAID-50 sold (albeit under names like "Disaster Recovery Site"), and such. It must be a challenge to sell a huge RAID-4 SAN... and then mirror it. Respect! It might also be possible to create a new BAARF logo (the old one is kind of outdated and people are getting tired of looking at it now after several days of availability on the open market) where it ends with a sentence like ".And all the powers that be.." I have actually just added your comment in the BAARF vers 2.doc and .htm documents. Should be available on the Internet RSN. Thanks for your idea. Best regards, Mogens Daniel W.

I think Steve has the correct response to us here, why sell 20 extra disks, when you can sell 6 controllers, 2gb cache, auto-balancing blah-di-blah software, 1000 biblio-bit fibre, installation consultancy and a partridge in a pear tree (oops maybe not the last one).

I guess I should count myself very fortunate. The folks here ask me about storage requirements, and listen. I get invited to meetings with our storage vendor and get to tell them what I want.

Call me a boy scout... I still try to overplan and get rid of kinks in advance (when I get more than one 32 or 64 GB LUN, that is) as the storage folks really get tired of: Oh, my I/O problem COULDN'T be caused by how you guys placed stuff on the frame!! You said it didn't matter where I put things... The cache takes care of all of that for me, right? You told me that it does, so it must. I'll just go recalibrate my scripts that detect I/O bottlenecks, they MUST be out of whack... COULDN'T be that you only gave me one controller to 500 GB and one to the mirror... My oltp database is sharing the same disks with the data warehouse on another server, you say? But doesn't that cache take...
