Compaq takes on EMC
Leakware
By Mike Magee, 29/01/2002 10:55:08 BST
A DOCUMENT SEEN by the INQUIRER shows how Compaq positions its Data Replication Manager (DRM) against EMC's Symmetric Remote Data Facility (SRDF).
The products let IT managers remotely copy data in case of catastrophes or for other reasons.
These sort of documents are used internally within Compaq to sell against competitors. µ
* IN OTHER NEWS, Compaq finally launched its "Blades" technology which uses ultra low power Pentium III chips to provide pizza-style boxes for telecoms and large corporations.
Data Replication Manager
Strengths and Weaknesses
Strengths
SAN-based architecture; data replication is preformed at the storage system level, and in the background to any host activity
New support for three FCIP vendors, CNT, SANcastle and SAN Valley
Supports copying over Fibre Channel, Wave Division Multiplexing (WDM), ATM with line speeds of T1/E1 through OC3.
Supports Fibre Channel distances up to 100 km with Very Long Distance GBIC
Unlimited distances over ATM and IP
Supports both synchronous and asynchronous data transfer
Supports Windows 2000/NT, Solaris, AIX, Tru64 UNIX, OpenVMS, HP-UX and Netware platforms.
Microsoft cluster and stretched cluster support, up to 100 km (fibre or ATM) between clusters
Heterogeneous SAN support for multiple operating systems across shared controllers
Batch script examples and best practices for failover/failback procedures
Multi-path support with SANworks Secure Path provides no single point of failure and load balancing
Qualified by Oracle Storage Compatibility Program in the area of remote mirroring in both synchronous and asynchronous modes
Support for cloning at initiator and target sites, and snapshot at target site
Recovery from link failures with Write History Logging and MiniMerge which guarantees "write order operation"
Easy to configure: customer can configure it, or Compaq Services can do it.
Lower cost solution compared to EMC SRDF
Weaknesses
Manual failover procedures
Bi-directional DRM requires separate controllers
Limited number of LUNs can used as copy sets, twelve RCS per controller pair
Command line interface, no GUI
SRDF
Strengths and Weaknesses Strengths
