EXAMINING NETWORK STORAGE Flashcards
What are Storage Area Networks?
High-speed, dedicated networks that provide access to consolidated, block-level data storage.
Designed to handle large volumes of data in enterprise environments and improved performance.
What are the connection protocols used in Storage Area Networks?
- Fibre Channel (FC)
- Fibre Channel over Ethernet (FCoE)
- InfiniBand
- iSCSI
These protocols facilitate data transmission in SAN environments.
What is Fibre Channel?
A high-speed network technology widely used in storage networking.
Supports multiple transmission speeds.
What are some of the Fibre Channel speeds?
- 1 Gbps (1GFC)
- 2 Gbps (2GFC)
- 4 Gbps (4GFC)
- 8 Gbps (8GFC)
- 16 Gbps (16GFC)
- 32 Gbps (32GFC)
- 128 Gbps (128GFC)
Each speed increment enhances performance to meet growing data demands.
True or False: Each speed increment in Fibre Channel corresponds with a new version of the Fibre Channel standard.
True
This includes improvements in technology, security, and efficiency.
Fill in the blank: The initial speed of Fibre Channel is _______.
1 Gbps (1GFC)
This foundational speed was critical for early SAN implementations.
What was the purpose of the 2 Gbps (2GFC) Fibre Channel speed?
Doubled the data transfer rate, improving performance.
This speed was introduced to meet the increasing demands for data.
What does the 16 Gbps (16GFC) Fibre Channel speed manage?
Larger, more data-intensive environments.
This speed is part of the progression to support modern data centers.
What are the latest Fibre Channel standards?
- 32 Gbps (32GFC)
- 128 Gbps (128GFC)
These standards provide high-speed connections for modern data centers.
What does SMB stand for?
SMB stands for Server Message Block.
What is the primary function of SMB?
SMB enables network file sharing.
What is SMB 1.0 used for?
SMB 1.0 is used for legacy systems.
What improvements does SMB 2.0 offer?
SMB 2.0 offers improved performance and security.
What enhancements does SMB 3.0 provide?
SMB 3.0 provides enhanced capabilities and encryption.
What does NFS stand for?
NFS stands for Network File System.
What is the primary function of NFS?
NFS facilitates file access over networks.
What is NFSv3 known for?
NFSv3 is known for stateless protocol operations.
What improvements does NFSv4 introduce?
NFSv4 introduces stateful operations and improved security.
What is the significance of NFSv4.1?
NFSv4.1 introduces parallel NFS (pNFS) for performance.
What does iSCSI stand for?
iSCSI stands for Internet Small Computer Systems Interface.
What is the function of iSCSI?
iSCSI allows for the transmission of block-level data over IP networks.
How does iSCSI work?
It utilizes iSCSI initiators to send data requests and iSCSI targets to receive and store them, streamlining storage management and access.
What does FCoE stand for?
FCoE stands for Fibre Channel over Ethernet.
What is the function of FCoE?
FCoE encapsulates Fibre Channel frames over Ethernet networks.
