4.10. CX200 Dual SP
4.10.1. Highlights
The CX200 Dual SP extends the CX full 2 Gb product family into the heart of the mid-tier storage
market. It offers the advanced functionality and connectivity required for this networked storage
environment. The CX200 Dual SP shares consistent software and identical architecture with the
CX400 and CX600. The CX200 belongs to the DAS line called NDAS.
The CX200 Dual SP is composed of one Disk Processor Enclosure (DPE), up to one Disk Array
Enclosures 2 Gbits (DAE2) and one Standby Power Supply (SPS) enclosure.
The DPE enclosure includes the 2 Storage Processors which offer in the front-end four 2Gb/s fibre
channel ports (two per storage processor) and in the back-end two dual 2Gb back-end fibre channel
loops to connect the DAE2. Each storage processor supports a 1GB memory cache. In addition to the
SP, the DPE includes up to 15 disk drives and 2 power supplies with integrated fans. A minimum of 5
drives is mandatory in the DPE and a sixth drive is requested in case of hot spare.
A DAE2 enclosure is a disk drawer which can include up to 15 drives. The CX200 Dual SP supports
up to one additionnal DAE2 to reach a total of 30 drives. CX200 Dual SP supports 36GB, 73 GB and
146GB 10krpm or 15 krpm drives. The SPS enclosure includes 2 SPS for redundancy purpose.
The CX200 Dual SP reaches a high level of performance for a medium range a new level of
performance for high bandwidth and high throughput demanding applications.
The CX200 Dual SP supports all the already known array based software provided in the previous
DAS : AccessLogix, SnapView and MirrorView.
The Access Logix software provides a secure, shared or selective access to the storage volumes in
both mixed and homogeneous platform environments.
The SnapView software is a non disruptive backup and recover enabler that facilitates increased data
availability. It provides a point in time image of information stored on a CX200 Dual SP, maintaining
a view of the data at the desired point and allowing access to that view for other uses such as backup
or application testing. An additional host is requested on AIX to run the application using the snapshot
copies.
The MirrorView software provides highly available data storage across several CX200 Dual SP,
CX400, CX600 and DAS4700, possibly at separate locations. By maintaining synchronous data
mirroring between the arrays, MirrorView ensures data availability of byte for byte mirrored images.
MirrorView is an array base software so that hosts are not impacted by this feature.
CX200 Dual SP supports also Powerpath that provides both load balancing to access data through the
different SP ports, and end to end failover capabilities. CX200 Dual SP does not support ATF.
The CX200 Dual SP can be shared by AIX and Windows servers using the [e-mail]! Manager.
Support of mix of AIX with other operating systems requires Access Logix.
Navisphere Manager Version 6 is mandatory to manage a CX200 Dual SP.
CX200 Dual SP supports various operating systems environments : Windows, AIX, Solaris, HP-UX,
Linux , Netware, …
