The Three Things That Matter

IBM Systems Storage


The Six “S”s of SAN - Servers

Server Planning is crucial to SAN Implementations:

– Operating System levels– Native File Systems– Device Drivers– Dual Path Device Drivers– iSCSI Drivers– HBA's and Their Microcode Levels

Understanding Application requirements and priorities – Important for introducing automated Policy Management and

implementing Tiered Storage and SLA’s.

Understanding Data requirements – Important for implementing virtualization – Storage and File System!

The Six “S”s of SAN – SAN Fabric Devices

8 Gb/s Fibre Channel coming in 2008 (FCP and FICON protocols)

– Brocade announced 8 Gb/s FCP on October 15, 2007

2007 - 10Gb/s for Trunking (ISL) between SANs

Higher Port Count Density in Directors and Core Switches

Blades/Modules to maintain investments in SAN Directors

SAN Routing is becoming important in managing large multi-site SANs

Application Availability

Reconfiguration

Migrations

Non-Disruptive Operations

Physical storage changes are not visibleto application servers

Complexity & Personnel Productivity

Most customer have storage from multiple vendors

Logical to Physical Mapping

Allows use of heterogeneous storage to beused regardless of storage provider

Management of storage can be performedin a common way from a single point ofmanagement

Storage Utilization

Capacity not efficiently used

Difficult to manage and monitor utilization

Virtual Storage Pools

Capacity can be allocated from multiple storagearrays

Management of capacity utilization can be donefrom a central point

Pools of different capabilities can be created

The Six “S”s of SAN - Storage Most Enterprise Storage at 4 Gb/s attachment in 2007

Moving to larger/faster disks - 300 GB 10k! 450GB or 600GB soon! Petabyte Systems on the near horizon. SATA disk are available.

HDD price/GB continues to erode but at a lower rate. – Matches areal density erosion rate

More advanced function software – Replication (Flash, Two Site (Synchronous or Asynchronous), Three Site) and LPAR

Storage is using SNIA Storage Management Initiative Specification (SMI-S)

Low end storage is shipping SATA with SAS interfaces (3Gb/s – 6Gb/s in 2008)

Large Scale low cost memory solutions in research labs– Recent news – nanowire based memory (10-100x times flash

memory)

Long Term – AFM Storage

IBM Systems Storage


The Six “S”s of SAN - Services

Planning for SANs is crucial

SAN skills are more available now, but still not plentiful

Implementing SANs can be very political - having a third party to arbitrate between groups can be effective

A Sampling of Industry Services Offerings:

– Storage Assessment

– SAN Planning and Implementation

– Virtualization Planning and Implementation

– Fibre Transport Services

IBM Systems Storage


Summary

Growth of storage continues unbounded, driven by unstructured data

Data protection and storage management require significant focus

Long-term digital preservation is a significant challenge– Media Migrating & Audit– Interpretation of the data – What application processes it at the end

Innovation in storage technologies continues– Memory Storage, Denser Disk and Tape, AFM Storage

Abstract

The Six "S"s of SAN" - Servers, SAN Fabric, Storage Virtualization, Storage, Software, Services

A good storage infrastructure is crucial to maximizing the informational value of a company’s data. It needs to provide reliable access to applications’ data, good I/O performance and have an appropriate cost in relation to the availability and performance requirements. Other attributes of flexibility, scalability and advanced functions such as instant copy and/or remote copy are also highly desirable.

Storage infrastructure architectures can range from Direct Attached Storage (DAS) to Network Attached Storage (NAS appliances or also know as Network File Servers) to Storage Area Networks (SANs) and finally to SANs augmented by various storage virtualization solutions. The combination of the architecture of customer choice with appropriate storage management practices, policies and procedures is key to improving customer’s data availability, data access performance and controlling costs.

Smaller companies can be quite successful with DAS or DAS + NAS solutions, although they have certain cost or flexibility inefficiencies if the company’s data grows significantly. Larger companies can benefit from the availability and scalability benefits of SAN or SANs + storage virtualization. NAS Gateways combined with SANs and/or SAN + storage virtualization is another good solution.

In this presentation we'll focus on each of the six elements of a SAN with an eye towards the latest industry trends in each.

NOTES:

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed.
