![]() ![]() I create a primary partition on /dev/sdf using fdisk and format it: mkfs -t xfs /dev/sdf1 I install the YUM packages for XFS support, by running: yum install kmod-xfs.x86_64 xfsprogs xfsdump I grab the public DNS information and connect to the server via ssh as root, using my EC2 identity. The management console informs me that the volume has been attached on /dev/sdf. I then attach the created volume to the instance I just started. You may have a different code, as I use a Europe based server. Get your 10GB EBS volume and then launch a large instance using the ami-ebe4cf9f AMI file (AMI stands for Amazon Machine Image), a CentOS 5.4 image file distributed by RightScale for a 64 bit architecture. The first step is to log into your Amazon AWS management console. This volume will contain Greenplum data directories (this time I will try with just one single volume – next time I will try with a volume per segment). I also decided to get a 10GB volume of Elastic Block Store (1 dollar a month), which I will format using the XFS file system. 4 EC2 Compute Units (2 virtual cores with 2 EC2 Compute Units each).EC2’s large instance has the following characteristics: My intention is to install it on a Large Instance running CentOS Linux 5.4 on Amazon. Greenplum Single Node Edition can be downloaded for free from the main website. On a multi-processor architecture, Greenplum Single Node Edition allows to create multiple segments (usually one per core) and hence to take advantage of parallel processing. The Single Node edition of Greenplum is a freely distributed version of Greenplum which can be installed on a single node. Greenplum SNE is a free version of the Greenplum database, one of the most advanced solutions for data warehousing and analytics, which is based on a shared nothing architecture and allows for data distribution and parallel processing on several nodes (servers). Do not worry, this test will only cost you a couple of dollars! ![]() If you wish to follow this article, you need to have an Amazon AWS account with a valid credit card. My intention is to do some benchmarking and spot the main differences in terms of performances between Greenplum Single Node Edition and PostgreSQL 8.4, my favourite DBMS. While still waiting to get our new servers installed here in our data centre in Italy, I decided to look at Amazon’s Elastic Compute Cloud (EC2) infrastructure. In order to do this, I need a multi-CPU environment. I have been thinking for a while now about adding Greenplum support to an open-source application for web analytics that I wrote a few years ago, which is called htMiner and uses PostgreSQL.
