V polovin\u011b dubna jsme kone\u010dn\u011b nav\u00fd\u0161ili i druhou optickou trasu na 1 Gbps<\/strong>, a tak m\u00e1me pln\u011b redundantn\u00ed konektivitu o t\u00e9to kapacit\u011b.<\/p>\n\n\n\n V sou\u010dasn\u00e9 dob\u011b b\u011b\u017e\u00ed p\u0159\u00edpravy na upgrade jedn\u00e9 trasy na 10 Gbps<\/strong>.

Sou\u010dasn\u011b s t\u00edm se p\u0159ipravujeme i my – vybrali jsme pot\u0159ebn\u00e9 routery a switche a v kv\u011btnu budeme intenzivn\u011b testovat. Samoz\u0159ejm\u011b o tom v\u0161em p\u0159ineseme podrobn\u011bj\u0161\u00ed informace, recenze a na\u0161e testy.

V serverovn\u011b je sice ji\u017e p\u016fl roku nast\u011bhov\u00e1no n\u011bkolik klimatiza\u010dn\u00edch jednotek, ale dote\u010f byly vypnut\u00e9. A\u017e do poloviny dubna n\u00e1m pln\u011b dosta\u010doval p\u0159\u00edm\u00fd freecooling<\/strong> – tedy chlazen\u00ed p\u0159\u00edm\u00fdm vh\u00e1n\u011bn\u00edm studen\u00e9ho vzduchu zvenku a odvod tepl\u00e9ho vzduchu ven.<\/p>\n\n\n\n Stoupaj\u00edc\u00ed teploty n\u00e1s v\u0161ak donutily jednu klimatiza\u010dn\u00ed jednotku zapojit. K tomu bylo nutno za na\u0161i budovu na „zahr\u00e1dku“ um\u00edstit venkovn\u00ed klimatiza\u010dn\u00ed jednotky. To je jejich do\u010dasn\u00e9 um\u00edst\u011bn\u00ed.

Budova velmi dob\u0159e akumuluje chlad i teplo, a tak se n\u00e1m p\u0159es noc v\u017edy vychlad\u00ed a p\u0159es den si s nashrom\u00e1\u017ed\u011bn\u00fdm chladem vysta\u010d\u00edme. To plat\u00ed dokud venkovn\u00ed teploty nep\u0159ekro\u010d\u00ed cca 18-20 stup\u0148\u016f<\/strong>. A\u017e bude dlouhodob\u011bji v\u00edce jak 18 stup\u0148\u016f, klimatizaci spust\u00edme – ale op\u011bt to bude sta\u010dit jen na p\u00e1r hodin denn\u011b.

P\u0159i provozu na polovi\u010dn\u00ed v\u00fdkon si bere proud cca 3x 40 A, nejv\u00edce energie spot\u0159ebuj\u00ed kompresory – to je na chlazen\u00ed to nejn\u00e1kladn\u011bj\u0161\u00ed.
