IBM blade server technology and features of blade server models of IBM, detailed explanations about them and brief introduction about its working, also covering a portion of disadvantages of servers which are addressed by new and reliable technology that is blade server
8. WHAT IS BLADE SERVER
TECHNOLOGY….!!?
-If we talk about servers then it consist of processors, memory,
network connections, but blade servers consist of a single circuit
board populated with all this.
-In a blade chassis you can have blade servers with different
configuration depending upon your usage and requirement , for ex-
you can have one blade server with Intel Xeon and another with Intel
Itanium , one with windows operating system and other with Linux.
-A blade server system is used in a clustering of servers that are
dedicated to a single task or multiple task.
9. ADVANTAGES OF BLADE SERVER…
• There are several advantages of blade server, they are as follows:-
1) less power consuming by consolidating power supply into blade
chassis
2) supports high performance
3) virtualization is highly supported
4) reduced cost because a single interface manage multiple servers
5) small in size
6) easily installed, upgraded, and maintained because blades can be
removed and added while system is up
7) share the resources like power supply, cooling fan, network switches,
interface card
8) in case of hardware failure the self diagnostics helps and faulty area
can be
10. DISADVANTAGES OF BLADE SERVER
• Initial configuration can be expensive in complex application
environments. This disadvantage comes with the fact that blade
servers are specialized computing equipment and their configuration
and administration is done by skilled persons.
• Its highly expensive if used for 5-10 blade servers, so better to use
stand alone servers, because each chassis is of the cost nearly
$5,000
• Individual stand-alone servers can be distributed throughout the
building and may not necessarily need special accommodations for
cooling, blade servers being very powerful these days produce
massive amounts of heat per square foot.
11. PARTS OF IBM BLADE SERVER
SYSTEM
1) CHASSIS: THE CHASSIS IS ALSO CALLED A CABINET, IT MAINLY HOLDS ALL SEVER BLADES
AND OTHER SHARED RESOURCES AMONG THEM.
2) SERVER BLADE: A SINGLE CIRCUIT BOARD POPULATED WITH COMPONENTS SUCH AS
PROCESSORS, MEMORY, AND NETWORK CONNECTIONS .
3) POWER SUPPLY UNITS: IT IS A SHARED RESOURCE AMONG ALL SERVER BLADES
4) FANS AS COOLING SYSTEM
5) STORAGE COMPONENTS: SAS DISK ARE USED, IT PROVIDES HIGH RATE DATA TRANSFER OF
3GB/S, ALSO SATA AND SCSI ARE USED
12. IBM BLADECENTER/CHASSIS
SPECIFICATIONS
• IBM blade centre is blade server
architecture
• In a standard server-rack configuration,
one rack unit or 1U—19 inches
(480 mm) wide and 1.75 inches
(44 mm) tall
• Each blade chassis can hold minimum
14-16 blade servers
• It consist of various chassis, they are :-
BladeCenter S, BladeCenter E,
BladeCenter H, BladeCenter T,
BladeCenter HT
• It contains minimum 6 power supply
and around 10 cooling fan per chassis
14. IBM BLADE SERVER SPECIFICATIONS
• In general, each server blade typically comes with one or two local ATA or SCSI hard drives which
are often hot swappable. Blade servers are also often designed to be easily connected to additional
storage pool, such as Network-Attached Storage (NAS), iSCSI Storage-Area Network (SAN), or Fibre
Channel.
• Expansion slots:- 1 CIOv slot (standard PCIe daughter cards) and 1 CFFh slot (high-speed PCIe
daughter card)
• Microprocessor:- Support for one dual-core, 64-bit microprocessor; 3.8 GHz or more
• Memory:- Dual-channel (DDR2) with 8 slots for very low profile (18.3 mm) DIMMs , Supports 1 GB,
2 GB, 4 GB, and 8 GB DDR2 DIMMs for a maximum of 64 GB
• Disk /bays:- (total/hot-swap)2 hot-swappable HDDs (SATA/SAS) or SSDs
• Maximum internal storage:- 2 TB
• Operating systems supported:- Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux
Enterprise, VMware
• Average size of a blade server:- (ex: IBM blade center JS12)
Height: 24.5 cm (9.7 inches)
Depth: 44.6 cm (17.6 inches)
16. WHY IBM BLADE SERVERS ARE BETTER
FROM OTHERS..!
• For pointing out defect even if blades are not working, where as in HP its not
possible to do so.
• IBM power management software are able to monitor the power per blade, per
chassis, & per module, whereas in Dell it cannot monitor per module.
• IBM offer to deliver your blades fully installed with third party apps & modules
integrated where Dell doesn’t provides this.
• IBM chassis can fit 14 redundant blades where HP only can fit 8 semi-redundant
blades in their chassis.
17. USES OF IBM BLADE SERVER
• Streaming audio and video content
• File sharing and serving
• Email messaging
• Databases hosting (Ms SQL, Oracle)
• Virtualization (VMWare, Microsoft Virtual Server, etc.)
• Blade servers are ideal for specific purposes such as web hosting and cluster
computing. For example Google is running blade servers in their data centres.
• Insurance companies and banks are big users of blade servers.
• Web hosting
• Cloud computing
18. AVERAGE COST OF IBM BLADE
SERVER SYSTEM
A SIMPLE SYSTEM CONSISTING OF A CHASSIS, ONE SERVER BLADE AND 2
SATA HDD COST OF INR-250000, SO ONE CAN ESTIMATE THE COST OF
THIS SYSTEMS.
