DUAL Processor E5-2420 enough for 5 Server VMs?

[msllc]

Hi All,

Our budget is stretched, and need to upgrade. Same ole same ole.

We have an existing server with the following hardware:

• Dual Intel® Xeon® Processor E5-2420 (15M Cache, 1.90 GHz, 7.20 GT/s Intel® QPI) - 12 Cores Total
• 96 GB of RAM
• 5TB in RAID 10 config
• Windows Server 2012 R2 - Hyper V Mode
• 2 QUAD NIC cards

We were hoping to setup the following VM's

• Domain Controller VM - supporting about 100 workstations
Windows Server 2012 R2
Active Directory
DNS
DHCP
Windows Update Services
Windows Deployment Services
File Sharing
Roaming Profiles
Symantec Endpoint Management
Roaming Profiles/Offline Folder Caching
Remote Web Workplace (Remote Desktop)
• SQL Database VM
Windows Server 2012 R2
Accounting Database (4 users)
CRM Database (10 users)
• SharePoint VM
Windows Server 2012 R2
• Win7/8 Workstation VM (for various little server apps that access Share Folders/Files)


In particular, I could use some advice on whether the E5-2420, 1.90 Ghz, processor (giving us 12 cores) is sufficient for setup this size. Or should we consider upgrading the processors with a higher Ghz and more cores? Was thinking of allocating 6 cores to the DC VM, and then 2 cores each to SQL and Sharepoint VM, and a single core to the Windows 7/8 workstation.

RAM seems sufficient to me (just need to divvy it up), but if anyone begs to differ, please let me know.

Could use any guidance as I am more a software guy than I am a hardware guru.

Thanks!

Sizing servers without knowing loads is not advisable.

I'd say "yes" and leave you with the consequences? If you have the server, give it a try. Intrinsically there isn't a problem in running 5 VMs on one processor. It has to do with loads.
