Novinky ohladne nested virtualizovaneho ESXi nad ESXi

Davam do pozornosti podporu VMware pre takmer plnohodnotny beh virtualizovaneho ESXi 5 hypervisora nad ESXi 5 hypervisorom. Taktiez prikladam link na postup, ako si otestovat VMware VSA storage appliance replication technologiu v takzvanom nested prostredi nad hypervisorom ESXi5.

Problem pri totalnom prechode na distributed switch

Pokial rozmyslate o prechode na techniku distributed switch, doporucujem porozmyslat o skale jej nasadenia. Existuje potencialne vazny problem pri uplnom prechode na distribuovany model kontroly virtualizovanej siete.
Prikladom moze byt situacia, ked su vsetky siete nakonfigurovane cez distribuovanu sietovu vrstvu, vCenter je virtualizovany a podkladovy ESXi/ESX server havaruje.

Enterprise riesenie centralizovanej kontroly VMs nastaveni od VMware

VMware predstavil novy enterprise produkt vCenter Configuration Manager pre centralnu kontrolu nastaveni virtualizovanych systemov. Prikladam link na prezentacne video, kde je mozne vidiet realnu silu riesenia. Doporucujem pozriet, velmi zaujimava zalezitost. Zaujimava bude urcite aj cena riesenia. :)

VMware riesenie pre aktualizovanie virtualizovanych systemov

Pokial ste pouzivali VMware Update Manager vo vSphere 4 pre aktualizovanie aplikacii a OS vasich virtualizovanych systemov, pravdepodobne vas nepotesi fakt, ze vo verzii vSphere 5 nie je tato moznost do nastroju Update Manager zakomponovana. Nastupcom ma byt v danej oblasti novy SMB produkt s nazvom VMware vCenter Protect Essentials, urceny pre aktualizovanie virtualizovanych systemov. Riesenie pouziva technologiu aktualizovania od spolocnosti Shavlik, ktora bola tento rok akvizovana spolocnostou VMware.

Co noveho vo VMFS-5?

vSphere 5 prinasa novy VMFS-5 filesystem. Zakladnou informaciou je, ze uz je mozne naformatovat VMFS datastore na kapacitu cez 2T. Druhou pozitivnou novinkou je moznost pripojit LUN Raw Device Mapping vo Physical Mode s vacsou ako 2T kapacitou.

Ked VAAI na EMC VMAX bezi pomalsie ako tradicna software metoda

When using VMware ESX or ESXi 4.1 versions in conjunction with EMC VMAX, vStorage APIs for Array Integration  (VAAI) Storage vMotion and cloning operations take longer to complete than when using Software (Host) Data Copy. As a result, performance degradation can occur.

Pozor na pripojenu fyzicku CDROM mechaniku!

Dnes som nasiel problem, ktory mi dlhodobo a pravidelne sposoboval vypadky dostupnosti virtualizovaneho servera. Na istu chvilu prestal sietovo komunikovat, asi 6-7 pingov, pocas coho prestala reagovat aj konzola vSphere klienta.
Log virtualnej stanice neukazoval pocas daneho pravidelneho vypadku absolutne nic.
Skusil som teda pozriet konfiguraciu virtualizovaneho hardware a nasiel som podozrive nastavenie CDROM, ktore mapovalo fyzicku CDROM mechaniku podkladoveho servera. Akonahle som nastavenie odstranil, vypadky prestali!

Takze pozor na namapovane fyzicke zariadenia!!!
