Asan administrator for the Contoso Corporation, you manage a large server that is running Windows Server 2016 and that has about 8 TB of disk space that you can allocate to be used by other servers. Describe how to configure the servers such that the two other servers running Windows Server 2016 can use the disk space just as if the disk space was local?

On the large server, you load the iSCSI Target Server role. You then configure the iSCSI Target Server using Server Manager. When you configure the server, you create multiple virtual disks and define which servers can use the virtual disk. Next, you configure the iSCSI initiators to connect to the volumes. Lastly, as you connect the virtual disk to each server, you use Computer Management to prepare the disks.

The requirements for a stretch cluster: Cont 1

Two sets of shared storage, using serial attached SCSI JBODs, Fibre Channel SAN, or iSCSI Target. Each storage set must be able to create at least two virtual disks, one for replicated data and one for logs. The sector size must be the same on all data disks on the physical storage.

When the drives are combined, Windows places them into a _______________________

Parity:

Writes data with parity information to protect against

Simple (no resiliency):

Writes one copy of your data but doesn't protect against drive failures; requires at least one drive

Three-way mirror:

Writes three copies of your data to protect against two simultaneous drive failures; requires at least five drives

Two-way mirror:

Writes two copies of your data to protect against a single drive failure; requires at least two drives

You have a new desktop running Windows Server 2016. However, you try to copy your file repository and find out that you do not have enough disk space. You have 400 GB of free disk space on your C drive and you have three smaller 500-GB drives. Describe the recommended course of action.

You can use the small drives and create a storage space and storage pool. Storage Spaces is a feature in Windows 10/Windows Server 2016that allows you to combine multiple disks into a single logical volume that can be mirrored to protect against one or more drive failures. When the drives are combined, Windows places them into a storage pool. These storage pools can then be segmented into multiple storage spaces, which are then formatted with a file system and can be used just like any other regular disk on your computer.

As an administrator, you are configuring an iSCSI Target Server role and multiple volumes that will be assigned to multiple servers using iSCSI initiators. Because these servers contain confidential information, you want to make sure that they are not accessed by other servers using an iSCSI initiator. Which of the following statements best describes the recommended course of action? a.You should specify the initiator ID that can connect when creating the iSCSI virtual disk. b.You should specify the initiator ID that can connect when creating the iSCSI target. c.You should enable IPsec. d.You should configure the iSCSI ACL list when he configures the iSCSI initiator.

You should specify the initiator ID that can connect when creating the iSCSI target.

SCSI Target Storage Provider

enables applications on a server that is connected to an iSCSI target to perform volume shadow copies of data on iSCSI virtual disks. It also enables you to manage iSCSI virtual disks by using older applications that require a Virtual Disk Service (VDS) hardware provider, such as using the DiskRAID command-line tool.

Multiple connected session (MCS)

enables multiple TCP/IP connections from the initiator to the target for the same iSCSI session

Spanned volumes

include two or more disks (up to 32) that are represented in Windows Explorer as a single drive letter.

A stretch cluster

is a Hyper-V cluster with nodes and storage in two locations. The cluster provides redundancy where the service provided by the cluster is still available, although one of the nodes is down or is not accessible.

Storage Spaces

is a feature in Windows Server 2016 that allows you to combine multiple disks into a single logical volume that can be mirrored to protect against one or more drive failures.

Network attached storage (NAS)

is a file-level data storage device that is connected to the server over a computer network to provide shared drives or folders, usually using Server Message Block (SMB) or Network File System (NFS).

Internet Small Computer System Interface (iSCSI)

is a protocol that enables clients to send SCSI commands over a TCP/IP network using TCP port 3260.

Storage area network (SAN)

is a storage architecture that allows systems to attach to the storage in the SAN and presents the drives to the server just as if the drives were locally attached.

Data Center Bridging (DCB)

is a suite of Institute of Electrical and Electronics Engineers (IEEE) standards that supports converged networks so network traffic can get sufficient bandwidth allocation, while maintaining reliability.

Storage Replica

is new in Windows Server 2016 and can be used to synchronize data on a block level on two independent storage units.

Server-to-server replication

is one of the simplest uses of storage replication where it replicates storage from one server to another server's storage. The requirements for server-to-server replication:

striped volume

is similar to creating a spanned volume in that almost all of the steps are the same. However, the way data is stored on a striped volume is different from a spanned volume

A cluster-to-cluster replication

is when one failover cluster replicates its storage to another cluster.

Internet Storage Name Service (iSNS)

protocol is used to discover, manage, and configure iSCSI devices automatically on a TCP/IP network.

SCSI Target Server

provides tools to create and manage iSCSI targets and virtual disks. Enabling iSCSI Target Server can provide application block storage, consolidate remote storage, provide for diskless boots, and run in a failover cluster environment.

converged network

shares a single network infrastructure that handles storage, data, voice, video, cluster, and management traffic.

With tiered storage,

you can combine the two types of disks into one virtual disk and volume.
