Current project with 3 vSphere 5.5. hosts. (Essentials plus, 2012 Datacentre on each, All local storage SSD for vSAN read/write caching, primary storage 15K SAS, Dell 720XD)
Current Network switches:
Core - 2 x 4948E (no 10Gb module)
Distribution: 2 x 3750E (no 10Gb module)
Access: 6 x 2960S 1GB
So, what are my options? Ideally I need 10Gb for vSAN for the 3 hosts. Will 10Gb module upgrade for the distribution switches cut it or do I need to think about 2 x 10Gb Switches? Can I present everything over the 10Gb links or should vSAN have its own physical port?
Not sure of my options here and what the best approach is?
