To list some very important items & agenda’s related to IT – Storage Budgets of 2009 are

 

  • Ø  Direct Impact Cost

o   Reducing Total Cost of Ownership

o   Reducing CapEx

o   Reducing OpEx

o   Storage Segment outsourcing

o   Reduce Cost of After Warranty Support

o   Reduction in Power Consumption

o   Reduction in Storage Management

o   Meeting SLA’s resulting in reduction in Penalties

  

 

  • Ø  Hidden Savings

o   Storage Virtualization

o   Increase Utilization & Efficiency

o   Storage Reclamation & Optimization

o   Redeploying unused storage

o   Trend Analysis and Forecasting

o   Unnecessary licensing cost for storage management software

o   Reduction in Floor Space

o   Centralized Storage

o   Storage Consolidation

o   Automation

o   Investment into long lasting technology

o   Planning resulting in future growth without heavy cost impact

o   Tiering using ILM approach

o   Green Data Center

 

Should I mention, “DO MORE WITH LESS”, the beaten up concept of 2009.

And the important aspect is how do you manage to achieve all of the above while your databases are growing, your file systems are growing and you do not have a luxury to spend any additional dollars this year?


Experience

Recently I had a chance to talk to a CIO from a Fortune 1000 customer, and during the conversation with him, we asked him about what the primary objectives he has for his organization related to Storage.

Some of the things he mentioned were increasing efficiency and utilization within his storage environments, reducing his OpEx with automation and consolidation, reducing his CapEx with leveraging his IT assets on the floor for 3 additional years after warranty and try to centralize the entire storage throughout all business groups for better management and OpEx/CapEx reduction.

 

Well, let’s move on to the next topic…….

What have you or the top management done in your organization to meet the IT – Storage budgets of 2009?

·         Client Usage Billing

o   Centralized Shared Storage

o   Centralized Management

o   Charge Backs and Bill Backs

o   Complex processes for Usage Billing

 

·         Database Growth

o   Ever growing databases

o   Database requirements in terms of storage

o   Database Log files

o   Log Shipping

o   Critical Applications around Databases

 

·         File System Growth

o   Ever Growing file systems

o   User Data

o   Business Process Data

 

While we talk about the IT – Storage Industry and its surrounding requirements and impact, we need to know the Storage Economics behind it.


While the File Systems are consistently growing, Databases are exponentially growing, Compliance is a must and business processes are becoming critical every day, how do we manage and leverage what we have plus help reduce CapEx / OpEx and still manage to keep uptime/ efficiency / utilization.


Example:

I recently had a chance to visit a MNC (Multi National Company) to talk about Storage. We had long 6 hour meetings with various Application Owners, Business Group Owners, Strategic Planning folks, member’s from the CIO’s office, Storage Administrator and Host Administrator. During these sessions, we asked them a few basic questions about their Storage environments related to usage, outages, charge backs, new acquisition, storage management, process management, etc.

It was very surprising to see disconnect of priorities that various different teams had based on the role they played in that organization. Certain folks were talking about budget reductions, while some had priorities to play around with the latest technologies, while some had priorities about the application uptime, while some were focused on growth and some thought about ease of use.

But during the entire time we did not hear any common messages from these various teams about efficiency and optimization of their Storage Environments …….


Well, let’s move on….

What do you do to keep up with the IT – Storage requirements?

Is someone helping you purchase new Storage?

March 16th, 2009 6 comments

In my previous posts on EMC Symmetrix 3, 5, 8 Series and EMC Symmetrix DMX, DMX-2 Series we discussed some important components that comprise in systems, in this post we will discuss some of the important components of EMC Symmetrix DMX-4.

EMC Symmetrix DMX-4 consist of 1 System Bay and (1 upto 8) Scalable Storage Bay’s. Each Storage Bay can hold up to 240 Disk Drives totaling 1920 drive in 8 Storage bays or 1024 TB System.  Systems  with special requirements can be configured to 2400 drives instead of standard 1920 drives.

The primary bay is the System Bay which includes all directors, service processor, adapters, etc, while the Storage Bay contains all the disk drives, etc.

 

System Bay (1 Bay)

Channel directors: Front End Directors (FC, ESCON, FICON, GigE, iSCSI), these are the I/O Directors.

Disk directors: Back End Directors (DA), these control the drives in the System.

Global memory directors: Mirrored Memory available with DMX-4, Memory Director sizes range from 8GB, 16GB, 32GB or 64GB totaling 512GB (256GB mirrored).

Disk adapters: Back End Adapters, they provide an interface to connect disk drives through the storage bays.

Channel adapters: Front End Adapters, they provide an interface for host connection (FC, ESCON, FICON, GigE, iSCSI).

Power supplies: 3 Phase Delta or WYE configuration, Zone A and Zone B based Power Supplies, maximum 8 of them in the system bay.

Power distribution units (PDU): One PDU per zone, 2 in total.

Power distribution panels (PDP): One PDP per zone, 2 in total, power on/off, main power.

Battery backup Unit (BBU): 2 Battery backup modules, 8 BBU units, between 3 to 5 mins of backup power in case of a catastrophic power failure.

Cooling fan modules: 3 Fans at the top of the bay to keep it cool.

Communications and Environmental Control (XCM) modules: Fabric and Environmental monitoring, 2 XCM located at the rear of the system bay. This is the message fabric, that is the interface between directors, drives, cache, etc. Environmental monitoring is used to monitor all the VPD (Vital Product Data).

Service processor components
:
Keyboard, Video, Display and Mouse. Used for remote monitoring, call home, diagnostics and configuration purposes.

UPS: UPS for the Service Processor

Silencers: Made of foam inside, different Silencers for System and Storage bay’s.

 

 

Storage bay (1 Bay Minimum to 8 Bay’s Maximum)

Disk drives: Combination of 73GB, 146GB, 300GB, 400GB, 450GB, 500GB, 1TB and now EFD’s 73GB, 146GB and 200GB available. Speed: 10K, 15K, 7.2K SATA are all compatible, each RAID Group and each drive enclosure should only have similar speed drives, similar type drives. 15 drives per Enclosure, 240 per bay, 1920 total in the system. If the color of the LED lights on the drive is Blue its 2GB speed, if the color of the LED is green, the speed is 4GB.

Drive Enclosure Units: 16 per Storage Bay, 15 drives per enclosure

Battery Backup Unit (BBU): 8 BBU modules per Storage bay, each BBU support 4 Drive enclosures
