What does database
storage management mean?
A database storage management
system is a defined set of hardware,
software and procedures to store the
data being use, called, manipulated,
etc.
Why is this important?
This topic is really important for and when it comes to data warehousing because you need to know how the information you are creating, is being stored and where it is being stored.
Also, you need to know how your
storage systems work just in case you
need to work on the storage system.
Also…
Another thing that is extremely
important when it comes to database storage systems is data protection.
How do we protect all the
information that we store, because if we store the
information, it must be important?
We have many ways from backing up
our systems with batch, full, or simple
backups, to restoring our database.
Oracle
Oracle has created a few things to make their database better
Automatic Storage System (ASM) – is an easy to manage, high quality service
database with automated database file management.
InServ with Thin Provisioning - is an
intelligent and broadly scalable disk array with automated storage administration and dynamic storage provisioning
Oracle cont.
ASM combined with the inServ Storage Servers with thin Provisioning, has
provided a widespread approach to
database file management and block-level data management. This move by Oracle is supposed to simplify database
administration operations, storage
provisioning and configuration, automates performance tuning, and is supposed to eliminate small manual tasks such as
performance tuning, special management and system resource tuning.
SQL Server
Microsoft has created a few things to make their database more powerful
iSCSI – is a standard SCSI block storage protocol that is designed to operate over TCP/IP instead of over Fiber. iSCSI based IP SANs (Storage Area Network) deliver lower total cost of ownership than traditional SANs and lower.
ONTAP - which revolutionized the landscape for customers who want to use the maximum spindle count on their SAN environments
without forgoing control of space management.
SQL Server cont.
FlexVol - is a logical storage entity that resides within an aggregate (is logical entity containing a pool of one or more RAID). Flexible volumes can be sized appropriately anytime for the unique requirements of each SQL Server
database instance. In addition, they can be grown and shrink as needed.
What do you think?
So which one should you use, Oracle or SQL Server?
Which one you find easier to use.
Both are very powerful databases, and both are always trying to make their databases quicker, more stable, better security, and easier to use.
