Data Storage in a Virtualized World
![Page 3: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/3.jpg)
Physical Infrastructure
In a purely physical environment, servers connect directly to storage. Storage may
be comprised of local disks or in an external array. The largest caveat to storage in a physical environment is
servers retain complete ownership of the physical device, with an entire disk drive or LUN connected to an individual server.
![Page 4: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/4.jpg)
Legacy storage
Many of the storage practices and procedures from the physical days have not changed for virtual environments.
Logical arrays for virtual environments still use common RAID configurations.
Adding storage was a cumbersome, time-consuming process involving downtime and service disruption.
Once storage was allocated, it was committed.
Forecast was more important with physical resources because of lack of mobility later.
Each physical server had its own device drivers for storage.
![Page 5: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/5.jpg)
Minimum 2 disks.
Excellent performance ( as
blocks are striped ).
No redundancy ( no mirror, no
parity ).
Don’t use this for any critical system.
RAID 0 - Striping
![Page 6: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/6.jpg)
Minimum 2 disksGood performance
(no striping, no parity).
Excellent redundancy ( as
blocks are mirrored ).
RAID 0 - Mirroring
![Page 7: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/7.jpg)
Minimum 3 disks. Good performance ( as blocks are striped ).
Good redundancy ( distributed parity ).
Best cost effective option providing both performance and redundancy. Use this for
DB that is heavily read oriented. Write operations
will be slow.
RAID 5 – Stripping with Parity
![Page 8: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/8.jpg)
Minimum 4 disks. This is also called as “stripe of mirrors”
Excellent redundancy ( as blocks are mirrored
)
Excellent performance ( as blocks are striped )
If you can afford the cost, this is the BEST
option for any mission critical applications
(especially databases).
RAID 10 – Striping and Mirroring
![Page 9: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/9.jpg)
A SAN is a dedicated network of disks providing access to consolidated, block level data storage.
SANs are primarily used to make disk arrays accessible to servers so that the devices appear
as locally attached devices.
Storage Area Network (SAN)
![Page 10: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/10.jpg)
Dual independent storage processing units. Proprietary operating system designed for one purpose –
high performance data access. Multiple high-speed disk channels. Redundant network, management, and iSCSI connections. Snapshot capabilities. Data replication for Disaster Recovery. Disk caching for faster I/O. Hot-swappable components eliminate downtime.

In virtual world, disk I/O considerations are more
important to properly optimize performance.

Virtualization
Virtualization involves the separation of a
resources fromthe underlying physical devices involved in the
delivery.

Virtualization Hosts
Hypervisor hosts: A piece of computing hardware that host virtual guest machines and directs the resources needed for the overall virtual platform.
![Page 14: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/14.jpg)
Centralized Storage for Virtualization
Provides for disk sharing on the virtualization
hosts.
High availability (HA)
Ability to migrate guests between
hosts.
Load balancing between hosts.

Storage Connectivity
• iSCSI: SCSI commands over IP networks.• Fibre Channel: High-speed fiber used for SANs.• FCoE: Fibre channel over Ethernet.
The SAN supports all common block-based storage connections:

Storage featuresProfile Driven Storage: Reduce the complexity regarding in storage selection by classifying storage according to user-defined policies.
Storage I/O Control: Prioritizes storage access by monitoring I/O load of a storage volume and dynamically allocating available I/O resources to VM according to defined criteria.
Storage Thin Provisioning: Dramatically increase VM storage utilization by enabling dynamic allocation and intelligent provisioning of physical storage capacity.
Storage APIs: Enhance your storage awareness, data protection, and array integration as well as take advantage of multi-pathing capabilities offered by third-party storage vendors.

Storage versatility
Change drive type without service interruption, i.e. from SATA to solid state.
Manipulate sizes of logical units and virtual hard drives.
Options between thin and thick provisioning.
Facilitates store protection through data replication.
Reclaim space surrendered by decommissioned virtual machines.
Ability to scale the storage solution by addition of disks and disk array expansion (DAE) units.

With or without sophisticated tools, most organizations should be able to classify many of
their key applications and have a clear understanding of the value of that data to the
business. This pattern of matching data and devices can then assign data to the optimal tier.

Data Classification – Understanding Your Data
![Page 19: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/19.jpg)
I/O intensive data represents up to 3% of online data and includes a variety of response time critical applications. This data typically resides on tier 0 Flash or tier 1 high-performance disk arrays.
Mission-critical data generally represents 12-20 % of online data and is the most valuable data to an enterprise, used in the critical business processes, revenue generating or customer facing applications. Data recovery times, the RTO (Recovery Time Objective), ranging from a minute or less up to an hour or two, are typically acceptable. Mission critical data usually reside on tier 0 or tier 1 storage based on the performance requirements.
Data Classification Categories – Understanding What They Mean
![Page 20: Data storage in a Virtualized World](https://reader033.fdocuments.in/reader033/viewer/2022051612/54c5e2f74a7959e4258b464b/html5/thumbnails/20.jpg)
Vital and sensitive data typically averages up to 20-25 % of all data stored online and represents the majority of data stored on disk. However, vital and sensitive data doesn’t require instantaneous recovery for the business to remain in operation. Data recovery times can normally take up to four or five hours without causing major operational impact .
Archival data presently represents approximately 43-60 % of all data stored online making it the largest category and at >60% CAGR, is the fastest growing data classification segment. Low activity, long term and infinite retention periods for data such as e-mail archives, compliance and legal records, medical information and images, video archives, photos and fixed content all fit this profile. Lost, corrupted or damaged data can be reconstructed with minimal effort, and acceptable recovery times can range from hours to days. Archival data is typically stored on the lowest cost storage systems, primarily automated tape storage, or other removable storage systems, in local and/or remote locations. Tier 3 data is the primary market for future tape growth and the prime opportunity for outsourcing data to cloud or other types of service providers.
