Od pond\u011blka jsem m\u011bl novou verzi \u0161kolen\u00ed vSAN 8 Install Configure and Manage. Tato nov\u00e1 verze spojuje 2 \u0161kolen\u00ed, kter\u00e1 byla na verzi 7 – „Plan and Deploy“ a „Management and Operation“.<\/p>\n

Shodou okolnost\u00ed jsem zaznamenal, \u017ee pr\u00e1v\u011b vy\u0161la nov\u00e1 verze zkou\u0161ky na Certifikaci vSAN Specialist. A vzhledem k tomu, \u017ee \u0161kolen\u00ed je nyn\u00ed u\u017e pouze 4 denn\u00ed, tak jsem si \u0159ekl, \u017ee vyu\u017eiji voln\u00fd den a p\u0159ihl\u00e1s\u00edm se na zkou\u0161ku.<\/p>\n

Necht\u011blo se mi nikam cestovat. Chv\u00e1la bohu u\u017e nen\u00ed pot\u0159eba<\/a>, d\u00e1 se to absolvovat odkudkoli – z domu, z kancel\u00e1\u0159e … pl\u00e1\u017ee … \ud83d\ude42 ) J\u00e1 teda zvolil kancel\u00e1\u0159.<\/p>\n

R\u00e1d bych se s V\u00e1mi pod\u011blil o n\u011bjak\u00e9 poznatky, a oblasti na kter\u00e9 je t\u0159eba se p\u0159ed zkou\u0161kou sezn\u00e1mit.<\/p>\n

  1. verze vSAN na kterou jsou ot\u00e1zky ps\u00e1ny je 8. \u010castokr\u00e1t je tam zm\u00edn\u011bno, jestli se pou\u017e\u00edv\u00e1 OSA (Original Storage Architecture)<\/strong> nebo ESA (Express Storage Architecture)<\/strong><\/li>\n
  2. Je dobr\u00e9 se sezn\u00e1mit s minim\u00e1ln\u00edmi po\u017eadavky na ESA (4 NVMe disky per server, 25Gb s\u00ed\u0165 … )<\/li>\n
  3. Nen\u00ed mo\u017eno ud\u011blat upgrade z vSAN 7.0 (OSA) na vSAN 8 ESA<\/li>\n

      2. Ujasnit si jak se vSAN chov\u00e1 v p\u0159\u00edpad\u011b, \u017ee je objekt Non-compliant, a Component m\u00e1 Absent<\/strong> nebo Degraded<\/strong><\/li>\n
