Data Center Temperature Control

Data centers with air conditioning by means of precision air conditioning units basically have two main types of control: the Control of air conditioning units based on the air inlet temperature (so-called return air temperature control) and the Control of air conditioning units based on the air outlet temperature (so-called supply air temperature control).
Return air temperature control is the best known and also the most widespread type of control. The CRAC or CRAH are equipped with temperature sensors (combined temperature and humidity sensors, as a rule) in the vicinity of the air inlet. A setpoint is set for the return air temperature and the unit controller keeps this setpoint stable. If the airflow is constant, fluctuations in the data center heat load influence the supply air temperature.
The supply air temperature is the temperature of the air as it leaves the air conditioning unit. It is approximately the same as the server inlet temperature. If the return air setpoint is set to 33 °C, for example, and the data center air conditioning system is designed for a temperature difference of 15 K, under full load the supply air temperature would be 18 °C. Since full load is seldom reached in a data center, but instead a partial load of 40 % to 60 % is common, the supply air temperature – at a constant airflow – would be 24 °C to 27 °C.
Diagram 1 shows the supply air temperatures produced at a return air temperature of 33 °C, a constant airflow and a temperature difference of 15 K at full load for various partial load scenarios.
Return air temperature control - diagram
Supply air temperature control has become ever more popular in recent years, because the server inlet temperature is increasingly required as a constant control variable. With the supply air temperature or server inlet temperature as the setpoint and a constant airflow, the return air temperature then varies as heat loads fluctuate. If the supply air setpoint is set e.g. to 18 °C, and the air conditioning system is designed for a temperature difference of 15 K, under full load the return air temperature would be 33 °C. With a partial load of 40 % to 60 % and a constant airflow, return air temperatures would lie at 24 °C to 27 °C.
Diagram 2 shows the return air temperatures produced at a supply air temperature of 18 °C, a constant airflow and a temperature difference of 15 K at full load for various partial load scenarios.



Supply air temperature control - Diagram
In the case of controllers that also adapt the airflow in line with partial load, the temperature difference changes only a little or not at all, the return air and supply air temperatures remain roughly the same, while the airflow varies.
This is due to the fact that the cooling capacity is also the product of the airflow and the temperature difference.
The decision whether to use return air temperature control or supply air temperature control should also factor in the air conditioning system as a whole. In systems with Free Cooling, the chosen type of control – return air temperature or supply air temperature control – has an influence on the efficiency of the air conditioning system. The definitive variable here is the supply air temperature.
Efficiency is inherently poorer in systems with supply air temperature control. This is also because the (low) supply air temperature is kept constant, i.e. all measures to make use of Free Cooling take place below this temperature level.
On the other hand, systems with return air temperature control have a supply air temperature that rises at partial load. Consequently, this increased supply air temperature can also be "produced" during Free Cooling when the outside air temperature is higher. If Free Cooling can be used just 1 K "longer", for instance, that is still several hundred hours' more Free Cooling.
Each type of control has its raison d'Γͺtre and you simply have to decide in each case which type is the most suitable for the data center in question.

ManageEngine Launches Log Analysis, Auditing Solution for Multi-Cloud Environments

ManageEngine Launches Log Analysis, Auditing Solution for Multi-Cloud Environments

ManageEngine, the real-time IT management company, today announced the launch of Cloud Security Plus, its log analysis and auditing solution for multi-cloud environments. Available immediately, Cloud Security Plus empowers enterprises to bolster public cloud security by collecting, monitoring and analyzing log information from both the Microsoft Azure and Amazon Web Services (AWS) environments and presenting that information in a single console.


ManageEngine will exhibit Cloud Security Plus along with the rest of its IT management and security portfolio at RSA Conference 2017 being held in San Francisco, February 13-17, 2017. Attendees who visit the company in Booth S2439, South Expo, will also have a chance to win a Star Wars drone by playing Hack Attack, the company's IT security-themed, virtual reality game.

Cloud Security Plus: Multi-Cloud Security from a Single, Web-Based Console
Log management plays an integral role in an enterprise's security strategy. However, logging in the public cloud is a challenge as access and controls are limited by the cloud providers. The complexity increases as organizations choose different providers for their IaaS and PaaS needs.
"The native cloud log management tools do not support multiple public cloud platforms. With these tools, extracting information for specific security needs is highly difficult," said Manikandan Thiagarajan, director of product management at ManageEngine. "Cloud Security Plus eases this task. It allows enterprises to centralize multi-cloud log data, provides exhaustive reports that present key insights, and offers the option to build custom reports and alert profiles."
Cloud Security Plus gathers log information from both the Microsoft Azure and AWS platforms and enables security administrators to easily keep track of activities happening at different layers. Highlights of this new solution include:
  • Comprehensive cloud log management: Collects, analyzes, archives, and performs search operations on log data from Microsoft Azure and AWS public cloud platforms.
  • Track user activities: Offers predefined reports that give in-depth information on critical IAM and user activities, security group and permission changes, and user login details.
  • Audit change activities: Tracks changes happening to critical resources including network security groups, Azure storage accounts, AWS WAF, AWS EBS and more.
  • Monitor business-critical applications: Ensures business continuity by monitoring critical applications such as the Azure SQL database and other databases hosted on AWS RDS, with detailed reports on all database activities.
  • Get key insights from critical resources on AWS: Provides out-of-the-box reports that give exhaustive information on activities happening on Amazon AWS S3, ELB, web application firewalls, and EC2 instances.
  • Perform log searches: Lets administrators perform forensic analysis and back track security events with an intuitive log search engine and advanced search options.
  • Get instant notifications: Provides administrators real-time email or SMS alerts about unusual activities, web attacks, anomalous trends and other security threats.
Hack Attack Game: IT Security + Virtual Reality = Star Wars Drone (possibility)
At RSA Conference 2017, visitors to the ManageEngine booth will have a chance to win a Star Wars drone by playing Hack Attack, an IT security-themed virtual reality game. Each day, the attendee with the highest score will win a drone.
In Hack Attack, the player is a sysadmin whose network is under siege from relentless security threats and attacks, embodied by futuristic bots that fly, crawl and storm the network from all directions. The sysadmin must eliminate these enemies by shooting them and utilizing ManageEngine product power-ups.
Register to play Hack Attack at RSA at http://ow.ly/fSHi308JA4O. The web version of the game will debut soon.

Pricing and Availability
Cloud Security Plus is available now and is licensed based on the number of cloud accounts added for monitoring. The pricing starts at $495 for a single cloud account. Add-ons, starting at $95, are available for monitoring additional cloud data sources. For more information about Cloud Security Plus, visit https://www.manageengine.com/cloud-security/index.html.

Mengembangkan kepribadian pemimpin atau pengurus ?

Benarlah sungguh kepribadian bangsa kita sedang diuji . Terutama dalam beberapa bulan ini . Dengan beragam geliat politik terkait Pilkada di banyak tempat, terutama di Jakarta sebagai ibukota kita.
Siapakah yang sedang kita cari dalam 101 Pilkada saat ini ? Apakah seorang pemimpin , atau seorang pengurus. Pengurus bukan pemimpin, tapi pemimpin pastilah pengurus . Pemimpin berfokus kepada sumber daya manusia untuk perubahan dan pertumbuhan, sedangkan pengurus melakukan tugas rutin yang telah ditentukan. Tapi kenyataannya, hampir semua calon peserta Pilkada bicara soal kepengurusan bukan kepemimpinan . Hal yang sama juga kita temukan dalam banyak perusahaan, baik skala kecil hingga besar.
Index Human Capital Index Indonesia 2016 berada di ranking 72 dari 130 negara (www.weforum.org) jauh kalah dibawah Singapora di ranking 13, bahkan Vietnam di ranking 68. Sungguh berat tantangan pengembangan sumber daya manusia Indonesia saat ini. 
Buku saku tentang H8 yang ditulis oleh Herald Siagian mengulas pendekatan unik untuk mengembangkan dan menerapkan kepemimpinan bagi kita semua, termasuk untuk para calon pemimpin yang akan berlaga di Pilkada. Para manajer muda, staf hingga pengusaha dan pemimpin dalam rentang usia 20-45 tahun sangat disarankan membaca buku ini.
H8 sendiri merupakan Pure Heart, Intellegent Head, Diligent Hands, Higher Performance / profit, Healthy Team, Good Habit, Never Hope-Less, dan Humble Leader. Semua ini dikemas dengan menarik, dengan mengenali dulu generasi yang akan dipimpin. Kemudian memahami tiga peran utama seorang pemimpin. Lalu dijabarkan empat prioritas pemimpin. Buku ini juga menjabarkan lima kualitas utama pemimpin. Tidak ketinggalan enam langkah mencetak pemimpin baru, serta tujuh gaya utama pemimpin, dan akhirnya membahas H8 Leadership Mix.
Semua ini disajikan dengan buku yang mudah dibawa kemana-mana, padat tapi tidak berat, dan saya sangat menyukai paparan ide dan gaya penjelasan lugas yang ditemukan di dalam tiap bab-nya. 
Memang buku ini sangat sarat dengan pengalaman yang penulisnya rasakan, serta berbobot tapi tidak merasakan berat dan memusingkan bagi para pembacanya, dan target terutamanya adalah para pemimpin, marketer yang berada di generasi X dan Y, dimana merupakan segmen usia yang paling banyak memerlukan bimbingan untuk menjadi para pemimpin baru. 
Kontak saya atau WA 0811107367 untuk mendapatkan buku H8 Leadership Development dan menjawab pertanyaan kita tadi, kita perlu mengembangkan kepribadian pemimpin ataukah pengurus ?
