Cert Guide - MCSA 70-740 Chapter 5 Server Storage, Latest updates, graded A+ Storage Spaces Direct - -This feature can use local, unshared storage to create highly available storage for hosting virtual machine files Storage Pools - -A collection of physical disks presented as logical disks Storage Spaces - -Virtual disks created from free space in a Storage Pool. These Virtual disks are like LUNs (Logical unit numbers) in a Storage Area Network (SAN) environment. This can be formatted to be NTFS or ReFS. Storage Management options - -- The Windows Storage Management API (Application Programming Interface) in Windows Management Instrumentation (WMI) - PowerShell - The File and Storage Services role in Server Manager Considerations for configuring Storage Spaces - -- Disk-sector size - Drive Allocation - Provisioning scheme Simple Storage Layout Options for Disks or Enclosures - -Features striping but no parity for resiliency; remember that striping means segments of data are written across multiple physical disks. Why would you choose this? performance improvements. Two-way & Three-Way Mirror Storage Layout Options for Disks or Enclosures - -These spaces support 2 or 3 way copies of the data they host; note that this stripes data across multiple physical disks. Parity Storage Layout Options for Disks or Enclosures - -This storage space technology is like RAID 5: Data is striped, along with parity information, across multiple physical drives; the parity information permits resiliency. True - -To create a storage pool, you need at least one physical disk. True or False? False, If you want to create a resilient mirror virtual disk, you need a minimum of two physical disks. - -If you want to create a resilient mirror virtual disk, you need a minimum of three physical disks. True or False? True - -To create a resilient virtual disk with parity, you need a minimum of three physical disks. True or False. False, For three-way mirroring resiliency, you need at least five physical disks. - -For three-way mirroring resiliency, you need at least four physical disks. True or False? True - -For your Storage space configuration, your disks must be blank and unformatted, with no volumes on any disk. True or False? False, Failover Clustering cannot use SATA, USB, or SCSI disks. - -Failover Clustering can use SATA, USB, or SCSI disks. True or False? Tiered Storage - -Disks of different speeds used optimally. Allows you to mix types of disks you use in a Storage space and use them efficiently. When you add an HDD and an SSD to a storage Space, Windows Server 2016 registers each type of disk and automatically creates two tiers. By default, each night at 1AM optimization of the disks occur. Manual optimization of tiered drives command - -Get-ScheduledTask -TaskName "Storage Tiers Optimization" | Start-ScheduledTask Set-FileStorageTier - -PowerShell cmdlet to pin files to certain tiers iSCSI Targets - -this advertises storage to iSCSI network, just like controllers for hard disk drives of locally attached storage. iSCSI initiator - -a Client on the iSCSI network iSCSI qualified name (IQN) - -this is a unique identifier that iSCSI uses to address initiators and targets on an iSCSI network. iSCSI Target Server role service - -this supports a software-based and hardware-independent iSCSI disk subsystem that can create iSCSI targets and iSCSI virtual disks of which you can use Server Manager to manage your iSCSI targets and virtual disks. Install-WindowsFeature - -Installs one or more roles, role services, or features on either the local or a specified remote server that is running Windows Server 2016. This cmdlet is equivalent to and replaces Add-WindowsFeature, the cmdlet that wa
