RE: Storage space overheads!
by Holland, William L 27 Jul '06

27 Jul '06

In a typical solution you lose 10% for WAFL overhead (disk serialization, mbr, etc). You then lose 5% for aggregate snap reserve and 20% for volume snap reserve. Actually, you don't lose the snap reserve space - this space is reserved to ensure enough space for typical snapshots (think of them as online backups). The snap reserve space can be changed. For instance, I always set the aggregate snap reserve to 0% -- I cannot foresee any situation where I would want to snap restore an entire aggregate. These numbers are for NAS. If you are using SAN (iSCSI or FCP LUNs) then you lose 50% of available space to be able to accommodate at least one full snapshot of the LUNs. To someone first starting out with NetApp solutions, these numbers sound horrible, I know I did. However, now that I've been using them for a few years I love it. The flexibility you get in disaster recovery, transferring data to other filers, etc is very much worth the tradeoff. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of margesimpson(a)hushmail.com Sent: Wednesday, July 26, 2006 9:38 PM To: toasters(a)mathworks.com Subject: Storage space overheads!

Also...if your using aggregates take another 5% off the top for Agg snapshot _____ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Glenn Walker Sent: Thursday, 27 July 2006 1:52 PM To: Glenn Dekhayser; margesimpson(a)hushmail.com Cc: toasters(a)mathworks.com Subject: RE: Storage space overheads! 10% overhead for WAFL, FYI. As to what Glenn says, I agree - start with storage space needed, then figure performance. Don't fill the remaining volume beyond 90% if possible (unless it's all archive-type data). As for your question before: If you use RaidDP, you'll lose 2 disks for every raid group (typically 16 disks total, or 14D+2P) The disks are right-sized (to ensure that every manufacturer has disks with the same size, start to end - ie, Hitachi and Seagate drives are NOT the same size in # blocks) You're left with # data disks * disk size, MINUS 10% WAFL overhead. After that, factor in snapshot reserve (20% by default) and space reservations if needed. In the case of 320GB ATA disks, the right size is actually 274400 MB (the 320GB is a raw or unformatted capacity - you can thank the ATA drive manufacturers for that misleading info). A RG of size 16 would net you 3457440MB after 10% overhead. If you don't need snapshots, that's your usable space - if you do need snapshot reserve, just subtract that from the total. Using LUNs (especially with snapdrive) changes the rules because of the 2x overhead it enforces. This is actually changed in with something called fractional reserve (snapdrive supports fractional reserve with SD 4.0 and ONTAP 7.1) The reason for all of the overhead: data protection. Netapp doesn't sell space - they sell insurance. They sell protection from data loss FIRST, then performance\manageability, and lastly space. I would say that NetApp has no more overhead than any other vendor that has snapshot like capabilities (and probably less given that everyone else is a copy-on-write implementation thusfar).

The most overused sentence: "It depends". When I design Netapp solutions, I work backwards from how much usable storage I'm going to need for the next 12-18 months. Then I also determine what kind of aggregate IOPS I'm going to need from my disks. From that, it's a fairly simple calculation. OK, so it's not; I have a complicated excel spreadsheet that I worked on for about a month before I was confident the answers were close enough to use in designs; but before you start putting everything together capacity wise you should have a good idea of how many disks you're going to need to satisfy your performance requirements. There's the obvious parity or dual-parity overhead, and the hot spare (or multiple hot spares, depending on how many disks you've got in the system). There's the snapshot reserve for NAS volumes (20% by default, you may need more or less)- but that reserve depends highly upon the amount of changes and deletes you have in a given volume. If you are using LUNs with snapshots, you need to multiple the size of the LUNs by 2.2 (2x for the overwrite reserve and another 20% for the internal data change rates inside a given lun, again change for your own environment). There's the WAFL RAID overhead; I've never gotten a real good feel for that but let's call it 5%- (anyone care to amend that?) Now also keep in mind that WAFL volumes don't really like to be more than 90% full because of the way they lay down data; I like to keep mine at 80% or lower. That's about all the overheads I can think of. Sound like a lot? Any vendor with snapshot technology is going to have the same issue of reserving loads of space for it, and they will use raid-5, which requires a net loss of one disk every 5-8 disks (and be slow under write load). Netapp goes 14 disks per parity (in either raid4 or dp). And everyone with a hardware raid has some raid overhead. Unless you're using raid 10, but then you're buying twice the disk, aren't you? Bottom line is that Netapp does require you to invest some of your disk in data and physical availability. It's well worth it, and it's comparable to every other enterprise system out there. If all you need is dumb disk with no overhead and no avanced features, there are plenty of RAID-0 solutions out there that will FC connect.
