We are going to buy HP Proliant Server DL380p Gen8, and we want to run vmware esxi 5.1. but I have problem with choosing the correct storage with the lack of budget. we have choice to buy 4x2TB SATA or 4x300GB 10K SAS or NAS (iSCSI support such as WD or Synology) but the price of these storage are completely different so I want to know:
- How much different between these storage in VMWare world? (our main problem is budget)
- Which RAID should I use? I heard that RAID 5 has reduce performance?
- Because it`s completely bare metal drive, How should I partition these drive? (Assume I used RAID 5 4x2TB?) I want to install 2 Windows server 2008 R2 for sql Server DB?
- Is it best practice to install the vmware hypervisor on USB?
what is the best practice for choosing storage for vmware esxi?
