Study Notes
Logical Unit Numbers (LUNs)
- LUNs are identifiers used in Storage Area Networks to direct data access.
- Each LUN corresponds to a specific logical storage unit, allowing efficient file retrieval.
Common SAN Network Technologies
- The primary technologies for SAN implementation are iSCSI and Fibre Channel.
- iSCSI uses IP networks, while Fibre Channel operates as a high-speed network dedicated to storage.
Advantages of Cloud Storage
- Cloud storage offers remote access to data, allowing users to recover files on different devices after loss or damage.
- Traditional storage risks data loss unless manually backed up.
Benefits of Solid State Drives (SSD)
- SSDs operate faster than mechanical disk drives.
- They have no moving parts, enhancing durability and reliability.
- Offer greater resilience against physical damage.
RAID and Parity
- A parity space storage layout is not similar to RAID 1, which mirrors data instead of using parity.
Mounting Virtual Disks in Linux
- The command
mount mydisk.img /mnt/vdiskis used to integrate virtual disks into the filesystem.
Boot Volume Information
- The \Windows folder is located on the boot volume, essential for system startup.
RAID Types for Redundancy
- RAID 5 provides redundancy through striping with parity, critical for data protection.
Virtual Disks Portability
- The statement regarding the portability disadvantage of virtual disks is false; they often offer flexibility in deployment.
Windows Server 2012 Data Management
- Data Deduplication in Windows Server 2012 identifies and reduces identical data sets on SAN storage to conserve space.
Partitioning Schemes
- GPT allows for larger disks compared to MBR, which is limited in size and number of partitions.
Reliable Disk Subsystem
- SAS (Serial Attached SCSI) is known for its reliability in enterprise and high-utilization settings.
Types of Disk Volumes
- Spanned Volume uses multiple physical disks sequentially without striping, ideal for expanding storage without redundancy.
Extended Partition Requirement
- To create logical drives, an extended partition must be set up due to MBR limitations.
Network Attached Storage (NAS)
- NAS features file sharing over standard protocols like SMB, NFS, and FTP, making it accessible and versatile.
SSD Capacity Misconception
- It's a misconception that SSDs will come in larger capacities than mechanical drives; they have traditionally lagged in this aspect.
Disk Management Commands
-
xtermis not a file or disk management command in Linux/Unix.
Local Storage Definition
- Local storage refers to hard drives or SSDs installed directly within a workstation.
Cyclic Redundancy Check (CRC) for GPT
- GPT uses CRC to enhance reliability and supports larger volume sizes, reducing data corruption risks.
Simple Space Storage Layout
- Similar to RAID 0, this storage layout does not provide fault tolerance and focuses on performance.
Windows Server 2012 Disk Pool Management
- When a disk pool becomes full, it automatically transitions to an offline state until additional storage is provided.
Terabyte Measurement
- One terabyte is equivalent to 1,000,000 megabytes (MB), a critical value for understanding storage capacity.
LVM and Physical Disk Partitions
- LVM refers to logical volume management, which utilizes physical partitions to create flexible storage options.
Backplane Technology
- Backplane systems use circuit boards instead of traditional cabling to transmit signals, enhancing data transfer efficiency.
Basic Disk Arrangement
- A basic disk follows traditional Windows or DOS partitioning, including primary and extended partitions, for effective disk management.
Boot Volume and Windows Folder
- The boot volume is integral for system startup, housing necessary files, including the \Windows folder for OS operations.
