[vpsFree.cz: community-list] Rozsirena kapacita zalohovaciho stroje

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Ahojte vsichni, dneska jsme nainstalovali k backuperu zajimavou technologickou tresnicku od Supermicro - 4U JBOD chassis pro 45 3.5" SATA2/SATA3/SAS/SAS2 disku :) Aktualne je v nem 9ks 3TB WD Red edition, takze mame na zalohovacim poli skoro k 20TB volneho mista a moznost rozsirit to o dalsich 64TB. Koho zajima vic detailu: Link na JBOD chassis: http://www.supermicro.com/products/chassis/4U/847/SC847E16-RJBOD1.cfm V backuperu je jeden LSI 9207-8i HBA radic (= neumi RAID, jenom prezentuje ty disky ze SAS2 sbernic systemu, o RAID atd. se u nas stara ZFS), SAS je hierarchicka sbernice, takze podobne jako na Ethernetu jde mit switchovanou stromovitou topologii - akorat se jim nerika switche, ale "expandery". Ten 9207 radic ma dva 8087 porty, coz jsou sdruzene 4 linky SAS2 a nejake management signalni vodice, celkem dosahujici propustnosti 4x 6Gbit, tzn. max 24 Gbit. Na jednom portu visi interni expander s 10 disky a 2 SSD, na druhem portu je prave pripojene tohle 4U chassis, ktere je tesne pod samotnym 2U backuperem. Na SASu je pekne, ze dokud staci ta hlavni 24 Gbit trubka a neni ucpana, daji se ty expandery retezit jeden za druhym. ZFS se s tim krasne vyporadalo a tak mame zalohy vyresene asi pro jednou finalne :) Pro zajimavost prikladam vystup zpool status ukazujici, jak prave vypada konfigurace toho diskoveho pole (prave tam bezi scrubbing, coz je neco jako linux mdraid re-check - proste se kontroluji a opravuji data na nahodne poskozeni kosmickym zarenim) -> [root(a)backuper.prg.vpsfree.cz] ~ # zpool status storage pool: storage state: ONLINE scan: scrub in progress since Fri Apr 26 16:35:06 2013 4.41T scanned out of 18.2T at 149M/s, 26h49m to go 0 repaired, 24.26% done config: NAME STATE READ WRITE CKSUM storage ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c4t50014EE602E08CBEd0 ONLINE 0 0 0 c4t50014EE602E0756Bd0 ONLINE 0 0 0 c4t50014EE602E09337d0 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 c4t50014EE003741AFEd0 ONLINE 0 0 0 c4t50014EE65835B4BDd0 ONLINE 0 0 0 c4t50014EE65835F6D1d0 ONLINE 0 0 0 raidz1-2 ONLINE 0 0 0 c4t50014EE65835F8FFd0 ONLINE 0 0 0 c4t50014EE65835FF98d0 ONLINE 0 0 0 c4t50014EE003742229d0 ONLINE 0 0 0 raidz1-4 ONLINE 0 0 0 c4t50014EE60326A73Dd0 ONLINE 0 0 0 c4t50014EE60326AA4Dd0 ONLINE 0 0 0 c4t50014EE60326A712d0 ONLINE 0 0 0 raidz1-5 ONLINE 0 0 0 c4t50014EE60326AA81d0 ONLINE 0 0 0 c4t50014EE6587C0A35d0 ONLINE 0 0 0 c4t50014EE603265E6Ed0 ONLINE 0 0 0 raidz1-6 ONLINE 0 0 0 c4t50014EE603266180d0 ONLINE 0 0 0 c4t50014EE60326A079d0 ONLINE 0 0 0 c4t50014EE6587C0A1Dd0 ONLINE 0 0 0 logs mirror-3 ONLINE 0 0 0 c4t5E83A97E60D6C045d0p5 ONLINE 0 0 0 c4t5E83A97E71BD0AF8d0p5 ONLINE 0 0 0 cache c4t5E83A97E60D6C045d0p6 ONLINE 0 0 0 c4t5E83A97E71BD0AF8d0p6 ONLINE 0 0 0 spares c4t50014EE003742689d0 AVAIL [root(a)backuper.prg.vpsfree.cz] ~ # zfs list storage/vpsfree.cz NAME USED AVAIL REFER MOUNTPOINT storage/vpsfree.cz 10.1T 19.8T 234K /storage/vpsfree.cz - -- S pozdravem Pavel Snajdr +421 948 816 186 | +420 720 107 791 | 110-010-956 CTO of Relbit | Predseda vpsFree.cz, o.s. | RHCE http://relbit.com | http://vpsfree.cz | https://www.redhat.com
