Ahojte,

tak je to tady, novy stroj dorazil a je nainstalovany.

Slibil jsem detailnejsi popis sestavy, takze tady je:

System:	Supermicro SuperServer 6027R-TRF [1]
CPU:	2x Intel Xeon E5 2630 (6core+HT, 2.3GHz) [2]
RAM:	128 GB celkem, 16ks Samsung M393B1K70DH0-YK0 [3]
SSD:	2x OCZ Vertex 3 240GB [4]
HDD:	6x WDC Black edition 1TB [5]

Software:

- - Scientific Linux 6 + RHEL6 OpenVZ
- - RAID1 512MB /boot (nad vsemi rotacnimi disky)
- - RAID1 240GB nad SSD, 8GB swap, zbytek flashcache caching device
- - RAID10 2.7T pro flashcache backing device
- - Facebook Flashcache ve writeback rezimu, 4k blocky (= nepotrebujeme
poustet TRIM)

Poznamky:

1. Desky X9DRi-F jsou uplne nedostupne, tak nam Abacus objednal na
jejich naklady o tisicovku drazsi X9DR3-F (ma SAS misto druheho SATA
radice)
2. SSDcka jsou v mirroru, zdalo se mi lepsi zajistit se proti
nahodnemu umreni spatne vyrobeneho kusu misto riskovani a
potencialniho snizovani wear-levelingu pomoci RAID0 (stripping)
3. Tahle sestava zvladne odhadem okolo 70ti VPS, ale neni to pevne
dane cislo, zalezi jak se ukaze a prokaze v praxi
4. 24 jader/vlaken v topu vypada fakt huste [6] :)
5. Teste se na masakr, vypada to, ze horsi HW uz kupovat nebudem, pro
ty netrpelive mam napovedu: kouknete se na titulni stranku Supermicro :)
