You are an Enterprise administrator for contoso.com. All the servers on the network run Windows Server 2008.
The company has assigned you the task to plan a data storage solution for the company by utilizing the existing network infrastructure and ensuring that the storage space to the servers is allocated as needed. You also need to ensure the maximum performance and the maximum fault tolerance in your solution.
To begin with, you decided to deploy eight file servers on the network and connect them to Ethernet switches. Which of the following options will you include next in your plan to accomplish the desired goal? (Select two. Each selected option will present a part of the answer.)
A.
Install Windows Server 2008 Datacenter Edition on each server.
B.
Install Windows Server 2008 Enterprise Edition on each server.
C.
Install Windows Server 2008 Standard Edition on each server.
D.
Deploy the servers in a failover cluster and deploy an iSCSI storage area network (SAN).
E.
Deploy the servers in a Network Load Balancing (NLB) cluster and map a network drive on each server to an external storage array.
F.
Deploy the servers in a Network Load Balancing (NLB) cluster and implement RAID 5 on each server.
G.
Deploy the servers in a failover cluster and deploy a Fibre Channel (FC) storage area network (SAN).
Explanation:
To plan a data storage solution for the company to ensure the maximum performance and the maximum fault tolerance, you need to install Windows Server 2008 Datacenter Edition on each server and deploy the servers in a failover cluster. Next deploy an iSCSI storage area network (SAN).
The Datacenter Edition supports both iSCSI storage and failover clustering. The failover clustering will ensure the fault tolerance. A popular SAN protocol, iSCSI allows clients to send SCSI commands to storage devices on remote servers. Unlike Fibre Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network infrastructure
The iSCSI is a protocol that allows two hosts to send SCSI commands over a TCP/IP network. By doing this, you can use SCSI but free yourself of the limitations of traditional SCSI cabling and, instead, use your LAN to connect your SCSI PCs and Server to your SCSI storage.
iSCSI is a type of storage area network (SAN) and it is typically compared to Fibre Channel (FC) – its much more expensive competitor. With iSCSI you have a client who needs access to the storage on the server. The client uses initiator software (making it the initiator) to connect to the storage server (called the target).
