Managing the large number of storage devices in the datacentre is a complex problem. Not everything uses the Storage Area Network (SAN) or Networked Attached Storage (NAS). A lot of data and machines still ship with Direct Attached Storage (DAS). The challenge is how to bring all of these into a single environment for the most efficient and secure usage.
This is where software vendor DataCore has found a niche and over the last two weeks, firstly at VMworld in Cannes and then at CeBIT in Hannover, they have been showing the latest features in their SANsymphony, SANmelody and Traveller CDP solutions…
With virtualisation high on everyone’s agenda, DataCore is allowing the support of 64-bit mega caches, allowing up to 1TB of data to be held in cache. This means that several virtual machines can be held in cache drastically improving response times for users. “To ensure resiliency”, Alexander Best says, “the cache is mirrored over multiple nodes. We have also extended the write cache from 2MB to 32MB per LUN and improved our global read-ahead cache schema.”…
DataCore is also targeting the delay in migrating virtual machines between physical machines and hypervisors with its Transporter software. Transporter can also be used as part of a backup solution moving snapshots to backup devices.
Tony Lock, Programme Director, Freeform Dynamics states:
…the most interesting announcement concerns DataCore’s “Transporter” which supplies Hypervisor Migration capabilities and better Integration to VMware Virtual Center.
” These functions could prove to be very useful as organisations begin to look at using multiple hypervisors in their environments and try to manage them as a pool rather than as a number of isolated islands of virtualisation. However DataCore needs to be very active to educate interested parties in how such functionality, and indeed the capabilities of its entire portfolio, can be exploited.”
