DTS M-cell Based Drives

• Unique M-cell drives
• 120 GB SSD with 1 GB intelligent memory
• Intelligent UPS (back up time of one minute)
• High data transfer rate compared to conventional
  drives.
• Lightweight unlike contemporary ones
• Its evaluation was carried out at N-SEECS

Performance Evaluation

• Our goal was
• Not only to measure the effectiveness of M-cell
  based drives.
• But also evaluation of combined effect of C-4
  PlatinumCache and DTS M-cell.
• C-4 is DTS product showing 10-100 improvement
  in carrying out IO operations
• Iometer, an open source tool used for M-cell
  drives evaluation.
• IO performance of conventional drives for
  comparative analysis of DTS products

4
Performance Evaluation Scenarios

• In order to fully measure the effectiveness of
  system We sought out four scenarios
• IO performance of Conventional drives
• IO performance of Conventional drives with C-4
• IO performance of M-cell drives
• IO performance of M-cell drives with C-4

5
Performance Evaluation- System Configurations

• The overall evaluation was carried out using the
  following system configurations
• Pentium (R) 3 GHz Processor
• 2 GB RAM
• 240 GB SATA SSD (M-cell based and conventional)
• Windows XP (Service Pack-2)
• Varying size of Read Write requests
• Varying level of sequential and Random data
  requests
• Now we discuss performance Results.

Scenario-1

• We evaluate the conventional SSD simply and
  observe their performance.

10
Scenario-II

• We apply C-4 on conventional SSDs and observe its
  performance showing much enhanced performance.

Scenario-III

• We perform the evaluation of M-cell based SSDs,
  which shows much improved behavior unlike
  conventional drives in terms of
• Total IOs
• Read IOs and
• Write IOs.
• Moreover DTS drives reduce Avg. Response time

Scenario-IV

• Here we apply C-4 on M-cell drives.
• It shows improvement in terms of reduced
  Response time.

Comparative Analysis

• Now we compare the results attained under
  different configurations which declare M-cell to
  be preferable in all respects

Conclusion

• The overall performance shown by M-cell is
  fabulous.
• The instilling of C-4 on system improves
  performance as well.
• In some cases if M-cell does not show IO
  improvement, it shows reduced response time
• We plan to evaluate m-cell on real time
  application.
