Sacrifice High Availability For High Performance?

January 31, 2018 by Jason Aw Leave a Comment

Mosey on over to the Fusion-io website and read my guest post in their blog, Do You Have to Sacrifice High Availability for High Performance?

Invitation to join our Webinar

After you are done there, view the joint SIOS and Fusion-io webinar “SQL Server 2008 – High Performance and High Availability Through Fusion-io and SIOS”. Part of this webinar includes some VERY interesting benchmark information…you won’t want to miss it!

Microsoft Now Officially Supports The iSCSI Software Target 3.3

January 31, 2018 by Jason Aw Leave a Comment

iSCSI Software Target 3.3 is now available for download

Just a few weeks ago I wrote an article about how to configure the iSCSI Software Target 3.3 in a cluster environment. While it is great for labs and testing, up until today it was not supported in a production environment. Well…that all changes today! Microsoft just announced that the iSCSI Software Target 3.3 is a freely available download and can be used on a production network.

DataKeeper Cluster Edition – High Availability/Disaster Recovery solution at great price

This all starts to get interesting once you start considering the possibility of building shared nothing iSCSI Target clusters with DataKeeper Cluster Edition. Build 2-nodes locally for High Availability and then place a 3rd one in a remote data center for Disaster Recovery. Now that is a pretty sweet HA/DR solution without having to break the bank!

Hyper-V Replica Coming In Windows Server “Next”

January 31, 2018 by Jason Aw Leave a Comment

Watch new feature Hyper-V Replica

Here is an interesting video that demonstrates “Hyper-V Replica”, a new feature coming in the next version of Windows. Skip to the 39 minute mark to see the demonstration.

It looks like a very welcome feature that certainly will make Hyper-V even more competitive when comparing the feature set vs. price between vSphere and Hyper-V, especially with the new pricing announced by VMware.

I’ll be very curious to see if this integrates with Windows Server Failover Clustering to allow you create shared nothing clusters as you can today with 3rd party replication software, which I’ve demonstrated using SteelEye DataKeeper Cluster Edition in an earlier blog post.

SQL Server Denali Demonstration

January 31, 2018 by Jason Aw Leave a Comment

SQL Server Denali Hadron Multi-site Cross Subnet Failover Video Demonstration

The crowd has spoken and the SQL Server Team has answered! Denali is the first version of SQL Server to support the cross subnet failover feature which first introduced in Windows Server 2008 Failover Clustering. It seems like we have been waiting forever for the SQL team to support this feature. Now, the wait is finally drawing to an end.

The following is a link to a 5 minute video. It demonstrates a 3-node cluster Denali cluster with two nodes in the primary datacenter, and one node in the Disaster Recovery site in a separate subnet.

I will be demonstrating this solution at Tech-Ed 2011 in Atlanta this week. Stop by the SIOS Technology booth and come have a look for yourself at the SQL Server Denali multi-site cluster demonstration using SteelEye DataKeeper. We would be happy to share our technology and further explain how it could benefit your projects.

Here is a great video from a friend of mine and former MVP Cluster Lead, Symon Perriman. It looks like he is enjoying his new job as Microsoft product evangelist.
