No.# Unlike hard disk drives (HDDs), NAND flash memory cannot overwrite existing data they must first erase old data before writing new data to the same location. With SSDs, GC is the name for the process of relocating existing data to new locations and allowing the surrounding invalid data to be erased. Flash memory is divided into blocks, which is further divided in pages. Data can be written directly into an empty page, but only whole blocks can be erased. Therefore, to reclaim the space taken up by invalid data, all the valid data from one block must be first copied and written into the empty pages of a new block. Only then can the invalid data in the original block be erased, making it ready for new valid data to be written.

No.# We are actually talking about SNMP Traps here

No.# If you want to specify only certain hosts from accessing a storage device then you would want to setup zoning. This configuration is done on the Fibre Channel switch

No.# DCB consists of the following 802.1 draft standards that specify how networking devices can interoperate within a unified data center fabric:

Priority-based Flow Control (PFC)
PFC is specified in the IEEE 802.1Qbb draft standard. This standard is part of the framework for the DCB interface.

PFC supports the reliable delivery of data by substantially reducing packet loss due to congestion. This allows loss-sensitive protocols, such as FCoE, to coexist with traditional loss-insensitive protocols over the same unified fabric.

PFC specifies a link-level flow control mechanism between directlyconnected peers. PFC is similar to IEEE 802.3 PAUSE frames but operates on individual 802.1p priority levels instead. This allows a receiver to pause a transmitter on any priority level.

Enhanced Transmission Selection (ETS)
ETS is a transmission selection algorithm (TSA) that is specified in the IEEE 802.1Qaz draft standard. This standard is part of the framework for the DCB interface.

ETS allocates bandwidth between traffic classes that are assigned to different IEEE 802.1p priority levels. Each traffic class is allocated a percentage of available bandwidth on the data link between directlyconnected peers. If a traffic class doesn't use its allocated bandwidth, ETS allows other traffic classes to use the available bandwidth that the traffic class is not using.

No.# The Cloud Data Management Interface defines the functional interface that applications will use to create, retrieve, update and delete data elements from the Cloud. As part of this interface the client will be able to discover the capabilities of the cloud storage offering and use this interface to manage containers and the data that is placed in them. In addition, metadata can be set on containers and their contained data elements through this interface.

No.# QSFP+ (Quad Small Form-Factor Pluggable Plus) modules offer customers a wide variety of high-density 40 Gigabit Ethernet.

No.# NAS file protocols are NFS,SMB and CIFS

No.# Capacity 1600 GB
Speed gain 4x read speed, no write speed gain
Fault tolerance 1-drive failure

No.# File level storage is seen and deployed in Network Attached Storage (NAS) systems.

No.# You configure the switches according to the vendor’s recommendations for iSCSI. These recommendations might include both configuration directives as well as code updates.

You must ensure the following:

You have two separate networks for high availability. Make sure that you isolate your iSCSI traffic to separate network segments.
You have enabled send and receive hardware flow control end to end.
You have disabled priority flow control.
If appropriate, you have enabled jumbo frames.
