This is new series of Symmetrix family with many new features a high performance, DMX (Direct Matrix Architecture). I will discuss what DMX Architecture is later.
There are two models in DMX-4 series the DMX-4 and the DMX-4 950. DMX-4 supports full connectivity to open system and mainframe hosts like ESCON and FICON.
The DMX-4 950 represents a lower entry point for DMX technology providing open system connectivity with FICON connection for mainframe hosts.
The DMX-4 is the world’s largest high end storage array, allowing configure from 96 to 2400 drives in a single system. Yes, 2400 drives!! Means you can have peta-byte storage in one box.
Main Features of DMX 4 are:
Mainframe Connectivity
4 Gb/s back-end support
Point to Point connection
SATA II drives support
Support Enginuity 5772 ( Enginuity is the Operating System for DMX)
Improved RAID 5 performance via multiple location RAID XOR calculation
Partial sector read hit improvement
128 TimeFinder/Snap session of the same source volume.
Improvements in
TimeFinder/Clone create and terminate times upto 10 times.
For SRDF, synchronous response time improvement up to 33 times.
Avoiding COFW (Copy on First Write) for TimeFinder/Clone target devices.
Symmetrix Virtual LUN
Clone to larger target device
RSA technology integrate called new feature Symmetrix Audit Log.
Improve Power Efficiency
RAID 6 supports
Separate Console to manage Symmetrix Management Console
DMX -4 Performance Feature:
Data Path: - 32-128
Data Bandwidth:- 32-128 GB/s
Message Bandwidth:- 4-6.4 GB/s
Global Memory:- 16-512 GB
DMX-4 Storage Capacity:
DMX-4 offers 73 GB, 146 GB, 300 GB and 400 GB FC Drives
DMX-4 offers 73 GB, 146 GB Flash Drives, 500 GB and 1 TB SATA II disk drives
Storage Protection:
Mirrored (RAID 1) – Not supported with Flash Drives
RAID 10, RAID 1/0 – Not supported with Flash Drives
SRDF
RAID 5(3+1) or RAID 5(7+1)
Raid 6 (6+2) or RAID 6 (14=2)- Not supported with Flash Drives.
What is “Tier 0” in Storage Environments?
Tier "0" is not new in storage market but for implementation purposes it has been difficult to accommodate because it requires best performance and lowest latency. Enterprise Flash disks (Solid State Disks) capable to meet this requirement. It is possible to get more performance for company most critical applications. The performance can be gained through using Flash drives supported in VMAX and DMX-4 systems. Read More →
