Solar Powered Data Centre

Electricity from 120 solar panels (owned and operated by the data centre) capable of generating up to 60 kilowatt-hours of electricity per day provides all power for data centre offices, air conditioners and all computer equipment (network and servers).


DC power from the solar panel feed is stored in battery banks. A large APC UPS (Uninterruptible Power Supply) system also provides power backup and conditions the power supply protecting equipment from voltage fluctuations and spikes.

In an emergency, power is also available from a natural gas standby generator (tested weekly) and regular grid supply, but in practice these options have never been used.
Solar tubes have been installed eliminating the need for electric lighting during daylight hours, saving even more energy.

24h System Monitoring

The data centre monitor our servers each minute, 24 hours per day, 7 days per week using three independent redundant monitoring systems. Alerts are sent to data centre technicians immediately in the case of any equipment malfunction.
We also remotely monitor all servers every minute from the UK. Any issues found will generate an email to our monitoring account and text messages to our support mobile phone.

Cisco Powered Network

Cisco Logo
Fully redundant Cisco powered network with multi homed connectivity to the Internet backbone: no single point of failure; multiple redundant Cisco 7200 series routers, Cisco PIX firewalls and Cisco switches.
The high availability network infrastructure is fully redundant with automated failover and full BGP (border gateway protocol) routing across three Internet service links (two wired and one very high speed wireless).
Data centre uptime guarantee to Athenaeum (Ecological Hosting) is 99.9+%.

VMware ESX Platform with VMotion

VMware IBM NetApp
The data centre operates VMware virtual server technology powered by multi-processor IBM xSeries servers with large amounts of onboard memory (RAM) and multi-terabyte RAID protected Fibre Channel SANs (storage area networks) from NetApp.
Compared to large numbers of individual physical servers this solution provides massive savings in data centre power consumption as well as noise and other environmental factors. In combination with the SAN and specialist software, each of the new physical servers is capable of running multiple virtual servers through the use of machine hardware emulation. These measures result in increased efficiency giving the ability to make more use of the resources available and generate considerable savings in energy consumption as well as reducing the overall amount of equipment required.
VMware VMotion brings a whole new level of redundancy to our server setup. If a physical server is struggling under the load or in the unlikely event of major hardware failure, VMware virtual servers hosted by the failing/failed physical server will automatically be switched to run on a different physical host. This is made possible by virtue of the servers being virtual and having all the server information stored away from the physical host in the SAN storage arrays.
The SAN also brings additional benefits: Multiple snapshots are taken of each virtual server stored on the SAN throughout the day. This enables server restoration to an earlier time almost instantaneously if needed. These snapshots are created by the SAN hardware and are completely independent of the servers.
Athenaeum (Ecological Hosting) has full remote control over our servers, including remote console access (i.e. even if the server is effectively off the Internet for some reason, we still have access as if we were sat in front of the computer), the ability to power cycle servers and server resource usage monitoring capabilities.

Technical Overview & Diagram

Below is a basic network diagram showing how the data centre network is laid out. The explanations that follow should be read in conjunction with the diagram.
Network Overview Diagram
There are three separate Internet backbones running BGP, which route all traffic coming in and out of network via the shortest possible path. BGP also allows complete redundancy, if one or two Internet backbone links goes down, the other(s) will continue to handle the traffic.
The three separate Internet connections then connect to two redundant Cisco 7200 series routers, which use HSRP (Hot Spare Router Protocol) allowing one to take over the other during a failure. From there, each one goes to separate trunked switches, which allows one to go down and the other will take over.
Two separate Cisco PIX firewalls operated by the data centre block all but needed ports and monitor each other, so if one goes down the other takes over. Out from the firewalls the traffic goes to another set of separate trunked switches, which can failover from one to the other if one fails.
At this point the servers connect to these switches as follows: Each server has two dual port NICs (network interface cards). NIC 1 Ethernet port 1 is teamed for failover with NIC 2 Ethernet port 1. And NIC 1 Ethernet port 2 is teamed for failover with NIC 2 Ethernet port 2. Then NIC 1 Ethernet port 1 and NIC 2 Ethernet port 2 are connected to Switch A-M, and NIC 1 Ethernet port 2 and NIC 2 Ethernet port 1 are connected to Switch B-M. Each of these two port separate NIC card teams are then teamed together for complete redundancy.
All servers are clustered together and each server has two separate SAN HBA (host bus adapter) cards that give the server redundant conductivity to the SAN. The SAN is a high-speed sub-network of shared storage devices. These storage devices are machines that contain nothing but RAID hard disks for storing data. The SAN's architecture works in a way that makes all storage devices available to all of the clustered servers. Because the data does not reside directly on any of the clustered servers, any server can go down and the other servers in the cluster will take over and balance the load.

UK Data Backup

Our Unix client shared hosting systems are synced to UK servers nightly for backup purposes. Due to data volume we only keep one nights worth. Important note: clients are responsible for their data and should keep full copies of their web sites and any associated data (e.g. databases), safe on their own systems. The backup referred to here is intended for disaster recovery only and is not part of the main service.

Nashar adalah seorang pelukis terkenal di Indonesia yang bermukim di Jakarta, Ia lahir di Pariaman sumatra barat pada tahun 1928. dengan teknik lukisan aliran bebas dari objek-objek manusia, hewan serta lingkungan yang di cari dan di lihat nya dan di lukiskan dengan abstraksi total.warna kecerahan yang di tonjolkan menceritakan kehidupannya sehari-hari.
Satu dari beberapa pelukis Nashar mempunyai sistem rumusan kredo tiga non  yaitu non konsep, objek dan tehnik, karena Nashar melukis suatu lukisan berdasarkan keinginan jiwa yang keluar dari diri nya sendiri.

Fadjar Sidik lahir di surabaya pada tahun 1930,
berawal dari dia bermukim di Bali selama 4th dari tahun 1957-1961 yang bermula beraliran seni lukis realis sekarang beralih ke abstrak pada tahun 60an, yang pada saat itu hanya melukis benda industri yang belum menjadi sebuah objek, dengan bakat yang ia punya, ia menggali bakat nya dan mengembangkan corak lukisan abstrak dengan dinamika keruangan, menggabungkan bentuk kotak serta bolatan2 yang menghasilkan sebuah karya lukisan yang elegan dan menjadi ciri khas dari karya seni Fadjar sidik.

Achmad Sadali yang lahir di garut pada tahun 1924, pelukis terkenal di indonesia yang berawal mengikuti pameran bersama pada tahun 1951. Dengan bakat seni yang dimilikinya berbeda, Achmad Sadali menuangkan karya seni abstrak dengan aksentuasi pada warna emas perada, yang mengisi dan membentuk bidang-bidang. yang selalu menjungjung tinggi kebesaran ILAHI.
Pada 30 Desember 1978, salah satu lukisannya yang berjudul Bidang Omber dan Sisa-sisa Emas, dengan latar gelap kehitaman. Di sana sini pada tempat yang tepat, ada pancaran warna emas. Komposisi lukisan vertikal pada bidang gambar yang horisontal.terpilih sebagai satu di antara tiga lukisan terbaik (bersama Lian Sahar dan Srihadi) pada Pameran Besar Seni Lukis Indonesia di TIM, Jakarta.
