Changes that made NAS Feasible for Databases
 Network Enhancements:
– Adaptation of Jumbo Gig E (9000 MTU)
– Network data separation
 Increases in Host Processing Capabilities:
– Increases in Mhz and Processing Power
– Decreases in cost of host RAM
 Industry Knowledge of Managing Database Objects
– Technology Knowledge Sharing: Web Training, Google,
MetaLink…
– DBAs are getting better at managing all database objects,
REDOs, temp tablspaces, init.ora …etc.

Changes that made NAS Feasible for Databases
 EMC NAS Storage optimizes response time
– Enhanced multi path access to disk information
– Cache rich environment
– Guaranteed referential integrity
– 8K UxFS Alignment to Oracle 8k Blocksizes
– Increases in MHZ and ram for NAS Device data movers

Why Jumbo Gig E ?
 The Alteon Jumbo Frame study:
– Jumbo Frames(9000MTU) provide 50% more throughput with
50% less CPU load than 1500 byte frames.
– Smaller frames usually mean more CPU interrupts and more
processing overhead for a given data transfer size.
 1500 MTU = +- 330 MB/Second throughput
 9000 MTU = +- 900 MB/Second throughput

8
What do Jumbo Frames do for Database
transactions ?
 It depends on how the database is writing/reading from
disk.
 Size of transaction and the number of transactions
 Generally Jumbo Frames will enhance OLTP
throughput by 10-20%
 Most performance gains are realized with DB
maintenance, then gains of 300% can be realized.

9
All Response factors
 E = CPU + k * I/O + m * PF
 E = transaction response time
 CPU = time for the number of CPU clock ticks
 k = time for each read/write operation
 I/O = number of disk read/write operations
 m = elapsed time for each page fault
 PF = page faults, or the number of times a program
needs another page of memory

Architecture Planning: Hardware Infrastructure
 Once properly setup Oracle EMC NAS Deployments
are very easy to manage going forward.
 Most organizations have the infrastructure and
personnel in place to facilitate rapid deployment of
storage using EMC tools
 A separate storage network with private VLANS must
be set up
 Review existing host infrastructure for jumbo GigE
(9000MTU) NIC Compatibility through entire storage
stack….Host and Switch(s)
 Two switches are recommended for DB High availability
and recovery

14
Architecture Planning: Database
 Number of databases which will reside on each array
 Size of the databases
 Type of database (OLTP, data warehouse …etc.)
 Combined peak I/O for all databases
 Segmentation of I/O by database object
 Number of concurrent users
 Database response time
 Other application activity on the storage
 Backup considerations

General NAS Architecture Guidelines for Oracle
 Standard Oracle physical disk separation for DB safety
 Separate Redo logs on at least two separate physical
disk stripe sets
 Present mounts for Redo logs down independent
network connections or VLANS
 If HA is required, place redo’s on separate switches
 Design NAS file systems to satisfy I/O demand from
each database object
 Design IP connections to balance or distribute disk I/O

EMC Oracle Database on NAS Accelerator Service
 Qualified DBs move to more cost effective storage
 EMC and Oracle conduct a thorough pre-site inspection
 Customer runs scripts supplied by Oracle and EMC are
run to gather workload data, also new databases
 Oracle and EMC will compile, review I/O stats, design,
and test NAS Solution
 Oracle and EMC Consultants perform: installation,
setup, knowledge transfer and documentation
 An industry leading EMC robust backup and recovery
process will be installed and set up to optimize Mean
Time to Recovery or (MTTR)

EMC Oracle Database on NAS Accelerator Service
 Working together, Oracle and EMC Technical
Specialists will perform the following steps on your
Database in eight consecutive days to completion:
 Project Scope and Organization
– Phase I – Planning
– Phase II – Design, Configure, and Test
– Phase III – Documentation, Overview, Acceptance

20
Phase I – Planning for a NAS Deployment
 EMC Technical Solutions Consultants works closely
with Oracle Consulting and your staff during this phase
to conduct these pre-site “discovery” tasks:
Run an analytical script in your environment which will:
–
–
–
–
–
–
–
Check for existence of specific patches/files
Server,O/S, DB Configurations (Source and Target)
Document the current DB file layout
Document the current storage array topology
Compile and study all I/O in the database
Detailed review and confirmation of the layout
Based on the results from pre-site probe, finalize and
document the existing configuration for an in-depth study
© 2003 EMC Corporation. All rights reserved.
21
Phase II – Design, Configure, and Test
Step 1 – Design
 Application and database mount point layout for optimal NAS
forward Engineering on an EMC NS600 NAS Storage array
 Specify network and hardware infrastructure requirements (if any)
 EMC will configure the NS600 and specify the right stripe depth for
each NAS file system based on required Database I/O.
 Oracle and EMC will design the backup and recovery process and
optimize MTTR using robust and patented EMC technologies
 A Test Plan will be set up to attain or exceed current service levels
