Your network contains two servers named Server1 and Server2 that run Windows Server 2008.
The servers have the Windows Server Hyper-V role installed.
You plan to host six virtual machines on Server1 and Server2. You plan to enable host clustering on Server1 and Server2. Each virtual machine will use Pass-Through Disk Access.
You need to recommend a storage configuration solution for Server1 and Server2 to support the planned virtual machines.
What should you recommend?
A. Configure internal storage on Server1 to contain six RAID disk arrays. Configure internal storage on Server2 to contain six RAID disk arrays.
B. Configure internal storage on Server1 to contain three RAID disk arrays. Configure internal storage on Server2 to contain three RAID disk arrays.
C. Configure an iSCSI device to contain a logical unit number (LUN) mapped to one RAID array.
Configure Server1 and Server2 to connect to the iSCSI device.
D. Configure an iSCSI device to contain six logical unit numbers (LUN) mapped to six volumes on one RAID array. Configure Server1 and Server2 to connect to the iSCSI device.
Correct Answer: D
Explanation/Reference:
Explanation:
To support the planned virtual machines for both the servers, you need to first Configure Server1 and Server2 to connect to the iSCSI device and then configure an iSCSI device to contain six logical unit numbers (LUN) mapped to six volumes on one RAID array. You must use SCSI if you need to expose more than 4 virtual disks to your guest. You must use IDE if your guest needs to boot to that virtual disk or if there are no Integration
Components in the guest OS. You can also use both IDE and SCSI with the same guest.You can use iSCSI to expose disks directly to the guest (which is the term used for virtual machine) OS (without ever exposing it to the host)
You need to configure an iSCSI device to contain six logical unit numbers (LUN) mapped to six volumes on one RAID array and not a logical unit number (LUN) mapped to one RAID array to modify the volume set capacity, RAID level and Stripe size.
