L’importanza dello storage
Dove risiedono le nostre VM?

In principio era la VSA
VMware VSA è stato il primo approccio al SDS da parte di VMware

SDS –Software Define Storage cos’è?
Software-defined storage (SDS) is an approach to data storage in
which the programming that controls storage-related tasks is
decoupled from the physical storage hardware.
At its most basic level, software defined storage is enterprise class
storage that uses standard hardware with all the important storage
and management functions performed in intelligent software.
Software defined storage delivers automated, policy-driven,
application-aware storage services through orchestration of the
underlining storage infrastructure in support of an overall software
defined environment.

SDS – l’idea centrale
Creare una piattaforma storage che permetta la
composizione dinamica di servizi
astratta dall’hardware sottostante

SDS - Perché?
Sempre maggiore varietà di device
• Hybrid, SSD, AFA
• server x86
• scale-out storage, cloud storage, object storage…
Problemi del modello operativo tradizionale
• Provisioning lento
• troubleshooting complesso
• complessità nel management
• …

Il Software Defined Data Center
Compute:
virtualizzare
tutte le
applicazioni
Network:
virtualizzare il
network
Storage: trasformarlo
per renderlo
rispondente ai
requisiti della
applicazioni
Automazione: i tool
di management
devono favorire
l’automazione
Il SDDC implica un paradigma operativo completamente automatizzato e
guidato dal software:
Policy e Orchestration

Virtual SAN VSAN
![Page 10: Software Defined Storage](https://reader031.vdocuments.us/reader031/viewer/2022030311/58eeb1e81a28abc4668b4617/html5/thumbnails/10.jpg)

VSAN – Architettura
esxi-01 esxi-02 esxi-03
VSAN network
vSphere Cluster
REPLICA-1 REPLICA-2
VSAN datastore
• Minimo 3 hosts, tutti con storage locale da
destinare alla VSAN
• E’ raccomandato che gli host abbiano
configurazioni simili
• Host: Scalabile fino a 64 host
• Dischi: dischi locali
o Hybrid: dischi magnetici e flash
o All-Flash: solo dispositivi flash
o Max 35 device capacitivi/nodo
o VMDK fino a 62TB
• Rete:
o 1GB Ethernet O
o 10GB Ethernet (preferito)
• Il componente “Witness” (fatto solo da
metadata) agisce da tie-breaker durante le
decisioni di availability

VSAN
Tutti i componenti (hw, driver, firmware) devono essere in HCL
Server certificati: VSAN Ready Node
Completamente integrata con vSphere e la vRealize Suite
Supporta tutto quello che è supportato nei datastore “tradizionali”
![Page 12: Software Defined Storage](https://reader031.vdocuments.us/reader031/viewer/2022030311/58eeb1e81a28abc4668b4617/html5/thumbnails/12.jpg)

vSphere Virtual Volumes
Gli amministratori definiscono le storage policies e le assegnano alle VM.
Quando viene fatto il provisioning della VM, VSAN interpreta la storage
policy e configura i device storage sottostanti in modo che soddisfino la
policy.
Quando la policy viene cambiata, VSAN riconfigura automaticamente le
risorse per soddisfare la nuova policy
