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:

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) ->
