Netapp Storage Architecture
Summary
TLDRThis tutorial delves into the architecture of NetApp storage, distinguishing between physical and logical layers. It explains the organization of disks into RAID groups for data safety and the creation of aggregates, which are collections of disk space with RAID groups. The logical layer involves mapping physical storage to containers, utilizing volumes and flex volumes to allocate disk space and serve files. The presentation aims to clarify the abstraction layers and the overall storage architecture of NetApp.
Takeaways
- 🗄️ The tutorial discusses storage architecture, focusing on two layers: the physical layer and the logical layer.
- 💾 Physical layer involves disks and hard drives, which are the actual storage devices where data is stored.
- 🔄 RAID (Redundant Array of Independent Disks) is introduced as a method for ensuring data safety and recovery in case of disk failure.
- 📚 RAID groups are created by combining physical disks, with different configurations like RAID 0, 1, 5, and 6, each offering different levels of data protection and performance.
- 🔗 An 'aggregate' in NetApp storage is a collection of physical disk space that contains one or more RAID groups.
- 🌐 The logical layer is about mapping physical storage resources to logical containers, which is a process managed by NetApp storage.
- 📂 In the logical layer, 'volumes' are used, which in the context of NetApp, are FlexVol volumes that can contain files and luns (logical units of storage).
- 📈 A FlexVol is an allocation of disk space that is a portion of the available space within an aggregate.
- 🔍 Aggregates contain RAID groups, which in turn consist of different types of disks, such as SATA, SAS, or SSDs.
- 📝 The architecture of NetApp storage is a series of abstraction layers starting from physical disks, to RAID groups, to aggregates, and finally to volumes and files.
- 👋 The tutorial concludes with an invitation to the next tutorial, indicating a series of educational content on the topic.
Q & A
What are the two main layers of storage architecture discussed in the tutorial?
-The two main layers of storage architecture discussed are the physical layer and the logical layer.
What are the physical storage devices mentioned in the script?
-The physical storage devices mentioned are disks, such as SAS disks or SSDs.
What is the purpose of RAID groups in the storage architecture?
-RAID groups are used to keep data safe on disks, allowing for data recovery in the event of a disk failure.
What does the term 'aggregate' refer to in the context of NetApp storage?
-An aggregate in NetApp storage is a collection of physical disk space that contains one or more RAID groups.
How are RAID groups and aggregates related in the storage architecture?
-Disks are grouped into RAID groups, and then one or more RAID groups are combined to create an aggregate.
What is the difference between the physical and logical layers in storage architecture?
-The physical layer involves the actual storage devices and their configurations, while the logical layer involves mapping physical storage resources to logical containers.
What is a FlexVol in the context of NetApp storage?
-A FlexVol is an allocation of disk space that is a portion of the available space within an aggregate.
How are files stored in the logical layer of the storage architecture?
-Files are stored within volumes, which are part of the logical layer of the storage architecture.
What is the significance of the abstraction layers in the storage architecture?
-The abstraction layers allow for a separation between the physical storage devices and the logical containers, making it easier to manage and allocate storage resources.
What is the role of volumes in the logical part of the storage architecture?
-Volumes serve as the allocation of disk space where files are stored and managed logically.
Can you provide an example of a RAID configuration mentioned in the script?
-The script mentions different RAID configurations like RAID 4, RAID 5, and RAID 6, which are configurations with different numbers of parities.
Outlines
💾 Introduction to Storage Architecture
This paragraph introduces the topic of the tutorial, focusing on storage architecture within NetApp storage systems. It explains the dual-layer structure of the architecture, consisting of a physical layer and a logical layer. The physical layer involves disks and RAID groups, which are used to ensure data safety and recovery in case of disk failure. The logical layer, on the other hand, is about mapping physical storage resources to logical containers, such as volumes and flex volumes, which contain files and are allocated disk space from aggregates. The paragraph sets the stage for a deeper dive into the configurations and workings of RAID and the abstraction layers of the storage system.

hello and welcome to this tutorial today
we want to talk about storage
architecture in the net of storage in an
atom storage we divided the search
architecture to two different layers one
is physical layer and the other one is
logical layer as you can see the picture
at the right here at the bottom we have
the disks and hard disks these are
physical dislikes era disk like SAS disk
or SSDs these are the discs at the end
of the day we are putting your data
inside we are gathering we are actually
combining and grouping these these
together equation something called the
rate group and if you're not familiar
with the term rates raid groups actually
do I mean the rate itself it's it's not
really the case right now don't worry
you will learn it in the next section
I'll talk about different configuration
of the raid and how they are working but
as as you may know the rate is just
redone that way of keeping the data safe
on the disks in order if you have a disk
failure we can recover the actual data
from disks and you can calculate
actually the data that is lost but
anyway so we are combining disks
physicalist winners and we are going to
create a red group and we have different
rates like rate for write DP or write
tech for free parities and we're
creating rate groups here and then we
are combining one or more than one I
mean two or three or different rate
groups together and then we are going to
create an aggregate so we have a term
aggregate ended in the NetApp storage so
in other word I can say that disks are
grouped into rate groups and I can say
that an aggregate is a collection of
physical disk space
that contain one or more raid groups
right so there are just different layers
that we are using here and at the end of
the day until here until this aggregate
I can say that
these are actually in the physical layer
so I can grab a picture for you here I
can show you that until he right
actually this part is the physical part
and the other part which is here
it's a usually illogical part so this
goes here this goes here so the storage
the actually the net up search what is
doing is just mapping the physical
surgery sources to logical containers
that's already this storage is actually
doing for the logical containers if I'm
going to talk about logical parts we
usually have volumes right in anatomical
flex while volumes and and inside actual
volumes we have lungs or we have all
files that we can serve the Dare out of
this these volumes and at the end of the
day we can say that F volume or a flex
volume is an allocation of disks right
disk space that is a portion of the
available space in the aggregate and the
aggregates also contains some rate
groups which we have read here at this
level if you take a look at closely you
can easily understand that these are
just some layer of abstractions we have
Long's and files inside the volumes and
the volumes are actually the free space
and the aggregates and the aggregates
are allocation of different rate groups
here which we have the physical rain on
them and then it's rate group consists
of different disks which could be Sailor
disks as disk SSD disks so here is the
actual architecture of the storage
NetApp storage hope you enjoyed this
tutorial and I'll see you in the next
one
