Technical Guide Book for PowerVault MD3200MD3220
Product Overview
The PowerVault MD3200 is the next generation series of directly connected shared SAS arrays replacing the
MD3000 product in the product portfolio. The MD3200 series of arrays provides vastly superior functionality
over its predecessor and is industry leading in the areas of performance, flexibility and scalability.
The MD3200 series of arrays were designed with performance in mind. Each controller is equipped with
four 6Gb SAS ports providing total aggregated bandwidth of 4,000MB/s of throughput for a dual controller
system which is 4X the throughput of the MD3000 and the most competitive products in the external RAID
SAS array market. For small block random access applications like databases, the MD3200 series is capable
of performing over 2X the IOP performance of the MD3000 making it a great platform for a wide variety of
applications and IT environments.
When it comes to flexibility, the MD3200 series of storage arrays is second to none. There are four base
offerings to choose from allowing users to best meet their specific IT demands and budgets.
MD3200 single controller model – A single RAID controller in a 2U, 12 drive 3.5” HDD enclosure provides the
lowest cost with the highest storage capacity offering when using large near-line SAS drives.
MD3200 dual controller model – Dual, active/active controllers in a 2U, 12 drive 3.5” HDD enclosure
provides a high availability and high capacity storage offering when using large near-line SAS drives.
MD3220 single controller model – A single RAID controller in a 2U, 24 drive 2.5” HDD enclosure provides a
low cost, high spindle count storage solution that maximizes IOPS when using SSD or 15K, 2.5” SAS drives.
MD3220 dual controller model – Dual, active/active controllers in a 2U, 24 drive 2.5” HDD enclosure
provides the combination of a highly available storage solution with a high spindle count to maximize IOPS
when using SSD or 15K, 2.5” SAS drives.
This series of arrays raises the bar for scalability in the entry-level storage space. Single controller models
are capable of support up to four hosts connected to a single array. Dual controller models are capable of
support up to four hosts with fully redundant I/O data paths or up to eight hosts with non-redunda nt da ta
paths. Additional storage capacity can be added up to a maximum of 96 HDD via the MD1200 and/or
MD1220 enclosures. Users can also mix 3.5” and 2.5” enclosures behind their base units in order to achieve
the optimal drive tiering that best matches their application needs. Within each enclosure users can mix
SSD, SAS and near-line SAS drives maximizing their return on investment.
In addition to the above mentioned features, the MD3200 series offers optional data protection features
like snap shots and virtual disk copy services to assist users in protecting their data in a more effective
manner. Initial set up is also much easier than the previous product with the addition of improvements in
the Modular Disk Storage Manager.
6Gb Serial Attached SCSI (SAS 2.0)
SAS provides a scalable point-to-point topology capable of addressing storage connectivity at many levels.
As SAS enters its second generation, the standard is evolving to enable better bandwidth utilization, easier
management mechanisms, and network robustness.
6Gb/s SAS 2.0 not only doubles the current data transfer rate it provides standardized zoning, selfdiscovery, and self-configuration methods to expanders. This makes larger and more complex topologies
easier than ever to implement.

Key features of SAS 2.0
• 6Gb/s SAS Signaling – doubles the transfer rate from 3Gb to 6Gb
• DFE (Decision Feedback Equalization) – increases cable limit to 10m ( 2 – 4 is typical)
• Supports SAS mini connectors (SFF-8088 and SFF-8087)
• SSC (Spread Spectrum Clocking ) – ease of design implementation – reduce peak amplitude
of radiated emissions
• Supports SED (Self-Encrypting Drive) with Instant Secure Erase
• Delivers 2
nd
generation SAS Discovery
• Standardized Zoning
• Expanded to 256
• Discovery executed by SAS Expanders
• Reduces time to discover large topologies

The RAID controllers are the “engines” or the “brains” of the MD3200 and MD3220 storage arrays. They
perform the RAID calculations, control the I/O movement, communicate with the management client, store

l
the firmware, and protect data until it can be written safely to the hard disk drives. The MD3200’s
architecture is designed to excel in multi-host systems environments. Its I/O system core provides built-in
hardware XOR for high-speed RAID parity calculations – enabling it to easily handle very compute-intensive
tasks. Each RAID controller contains 2GB of cache for a total of 4GB of cache in a dual controller
configuration which is mirrored with the other controller’s cache for high availability. In the event of a
power failure, the controllers are protected with battery assisted persistent cache backup which destages
cache to non-volatile media for indefinite safe keeping.
Each controller has a 36-port 6 Gb/s SAS expander that provides access to the drives in the MD3200 or
MD3220 enclosure. The SAS expanders enable each controller to access all of the drive ports, creating
active/active drives loops that provide both controllers redundant access to all attached disk drives.
Each controller has the following external connections:
• Four 6Gb SAS ports for host connectivity
• One 6 Gb/s SAS port for drive enclosure expansion for additional capacity
• One Ethernet management ports for LAN out-of-band ma na g eme nt
• One PS/2 serial interface for service
