Hello everyone, in this post we will look at implementing storage tiers in our Hadoop HDFS cluster. This feature has been supported since Hadoop v2.3, and has gained a huge popularity at present, especially when companies doesn’t want to invest heavily on compute and storage to handle COLD Data. Storage tiering gives us the flexibility…… Continue reading Heterogeneous Storage and Archival with HDFS
There are few complications for doing a “migration” of CA role as the old CA name matches with the server hostname. I’ve faced this and after referring Tech articles and chatting few tech guys, I’ve successfully achieved this, so thought to blog this, and might be helpful to someone. The simple scenario below is a…… Continue reading AD Certificate Services Migration – How to do with suitable regression plans? When the CA name matches the hostname?
Hello everyone, I just got to work on a daisy chain unified setup with Dell Powervault MD 1200, it was an interesting experience,so I thought to blog it. Configuration Compute : 3 x Dell Poweredge R720 with dual Perc H810 HBA cards . Storage : 4 x Dell Powervault MD1200 with dual Enclosure Management Modules (EMM),…… Continue reading Walkthrough – Dell Powervault MD 1200
Today I tested a very nice feature available with Windows Server 2016, called Switch Embeddded Teaming (SET), so I thought to blog this. Before (With Windows Server 2012 R2) Windows Server 2012 introduced the support for RDMA NICs for higher throughput by utilizing the full capabilities of SMB 3.0 including SMB direct and SMB multichannel…… Continue reading Switch Embedded Teaming to replace the traditional NIC Teaming for Hyper-V
When it comes to designing a storage solution for your compute cluster, the main areas to consider are capacity and performance benchmarking. Performance benchmarking should be done at both storage level and at network level. At storage level, we deal primarily with what is known as IOPS – Read IOPS and write IOPS. Storage Level – RAID…… Continue reading Storage Performance benchmarking
