'Shared Nothing' architecture is not a new concept that is going to phase out the SAN based architecture. It’s just a precursor to the latter.

Here is a brief look at the evolution of the two architectures that would make this point obvious…

Storage Area Network

'Storage Area Network' is a dedicated network for providing access of block storage devices to a set of servers or hosts. Let’s see how this has evolved over the years...

Initially storage devices came bundled with the hosts and this posed challenges when the host had to undergo a hardware maintenance shutdown in order to add more storage. Also the number of storage devices that can be connected to the internal SCSI bus was limited. This brought in the concept of direct attached storage where the host and the storage were separate physical boxes connected by a cable (initially parallel SCSI and then Fibre Channel). The storage box was...

Service level agreements (SLAs) must be met whether you’re keeping mission-critical data centers running or serving up frosty beverages. Disasters, configuration errors, poor performance, thirsty customers…it’s an ever-changing race to keep your operation available, fast, and resilient. Let us show you what our customers are doing to meet the challenge of delivering on SLAs.

The performance gap between computing devices and storage devices has been growing for several years. Currently, CPU and DRAM operations are measured in nanoseconds while hard disk drive (HDD) operations are measured in milliseconds – that is several orders of magnitude difference.  Enterprises are increasingly looking at SSD/Flash storage to help narrow this performance gap.

Join the Symantec Storage team on Wednesday, August 21 at 9:30am PT to learn about the growing reliance on SSD/Flash to optimize storage environments, discuss the benefits and risks, and examine...

DCIG (Data Center Infrastructure Group Inc.) released their High Availability and Clustering Software Buyer's Guide (attached to this email) that weights, scores and ranks over 60 features on 13 different software solutions from 10 different software providers. Symantec's Veritas Cluster Server (VCS) achieved the "Best-in-Class" ranking and earned the top spot in this inaugural DCIG High Availability and Clustering Software Buyer's Guide.

VCS earned the only “Best-in-Class” ranking, and for good reason. VCS ranked “Best-in-Class” and/or “Excellent” in every single category that DCIG evaluated. Categories ranged from operating environment to management capabilities. DCIG mentioned, “Making Symantec’s achievement so impressive was that it’s in a highly competitive space where most high availability and clustering software packages only focus on a few or even only one operating...

Goal

we wanted to change the paths of the vxdmp disks without reboot and outage to the existing vxfs filesystems on Solaris 10

Result

Not possible.

Reason

as long as the path is in a disk which is imported,

 cfgadm -al -o show_SCSI_LUN|grep failing 

shows the disks as failing not unusable

even though the disk is offline in format and "vxdisk path" shows the path as disabled.

What I think about this

why can't there be a command to allow us to remove the path completely in vxdmp? the issue would have been easily resolved. I can't see why this function is not provided.

We live in a time when disruption to critical IT systems can have devastating effects on the day-to-day operation of business. Whether these service interruptions come in the form of security threats, configuration errors, power outages, natural disasters, or technology upgrades, Business Continuity needs to go beyond simply protecting data or meeting Service Level Agreements (SLAs). Continuity must be maintained while embracing virtualization, cloud and other new technologies.

Tune in to the next installment of our Google+ Hangout Virtual Vision series for a more in-depth discussion from our Symantec experts, Paul Belk and Arun Balakrishnan, to learn about best practices and technologies for protecting your data wherever it resides and keeping applications highly available. You can also join in the conversation by using the hashtag #SYMChangout.

Executive Summary

Symantec conducted a survey on IT disaster recovery and high availability and customer responses revealed the following key aspects:

   - Business Continuity market opportunity exists for a distinct product that focuses on Disaster Recovery (DR) across multiple data center sites

   - Many customers have multivendor environments and there is a market need for standardized virtualization agnostic solutions (20% of respondents)

   - Per Virtual Machine and Per CPU licensing models constitute 90% of current DR product licensing schemes

 

Introduction

When a disaster, natural or otherwise impacts normal operations of a business, Disaster Recovery (DR) processes kick in to ensure that services remain available. The effectiveness of a plan is measured by how long it takes the business to recover the critical services (Recovery Time Objective or RTO) and how much data is lost in the...
