Part B (3 Marks)

Exercise 3: Storage Design (1 Mark)

Design Storage Solution for New Application

Scenario

An organization is deploying a new business application in their environment. The new application requires 1TB of storage space for business and application data. During peak workload, application is expected to generate 4900 IOPS (I/O per second) with typical I/O data block size of 4KB.

The vendor available disk drive option is 15,000 rpm drive with 100 GB capacity. Other specifications of the drives are:

Average Seek time = 5 millisecond and data transfer rate = 40 MB/sec.

You are required to calculate the required number of disk drives that can meet both capacity and performance requirements of an application.

Hint:In order to calculate the IOPS from average seek time, data transfer rate, disk rpm and data block size refer slide 28 in week 6lecture slide. Once you have IOPS, refer slide 29 in week 6 to calculate the required number of disks.

Exercise 4: Storage Evolution(2 Marks)

Watch the following videos for Fiber Channel over Ethernet and answer the questions that follow:

− http://www.youtube.com/watch?v=hSFyf-rmjA8

− http://www.youtube.com/watch?v=iCfJCzfNLrw

What is FCoE and why we need FCoE?

________________________________________________________________

In your opinion how FCoE is cost effective than traditional connection – give brief explanation.

________________________________________________________________

You have read and answered about SAN in part A – based on your understanding and with some research effort answers the following questions:

What is a Virtual SAN?

________________________________________________________________

What is IP SAN protocols and FibreChannel over IP (FCIP)?

________________________________________________________________

c. Stores both objects and objects IDs

d. Controls functioning of storage devices

What is used to generate an object ID in a CAS system?

a. File metadata

b. Source and destination address

c. Binary representation of data

d. File system type and ownership

What accurately describes block I/O access in a unified storage?

a. I/O traverse NAS head and storage controller to disk

b. I/O traverse OSD node and storage controller to disk

c. I/O traverse storage controller to disk

d. I/O is directly sent to the disk

What accurately describes unified storage?

a. Provides block, file, and object-based access within one platform

b. Provides block and file storage access using objects

c. Supports block and file access using flat address space
