Architectural Choices
Architecture Direct to Target - LAN Proxy Based – LAN Proxy-Based – LAN Free
Advantages Simultaneous backups easily accommodated and scaled (direct to target & control via ESX/LUN/Application maxima)
Easily scaled at target side via adding additional CIFS targets
Simple to install and enable, no SAN expertise req’d
ESXi Support leveraging vStorage APIs
No pressure on LAN/SC/Management network
Easy if existing methodology has been VCB/vStorage API
Leverage SAN investment
Considerations Changes required to SC Mem/CPU reservation for injected run-time agent
Additional load on SC/Management console
ESXi Not supported
Proxy a potential bottle neck (multiple proxies possible)
Requires traffic on Management LAN
Proxy a potential bottle neck (multiple proxies possible – only 1 per group of LUNs)
All LUNs can only be backed up via a single proxy, creating a potential bottleneck
Configuration on SAN required, non-trivial without in-house storage expertise
11
Requirements for LAN free backups
• vRanger Pro 4.2 installed on a physical proxy server• One proxy per set of VMFS luns• VMFS luns zoned so vRanger Pro can see and read them• VCB application is no longer used• Works with ESX 3.0.2 - ESX 4 (vSphere)• ESX 4 hosts require minimum “Essentials” license to use the
vStorage API.• DISABLE AUTOMOUNT!!!! DO NOT WRITE DISK SIGNATURES!!!
