13. Key software feature – SSD Cache SSD Cache with SSD wear level information  Accelerated read performance for hot data, suitable for random read- intensive applications such as OLTP, Microsoft SQL, mail servers, CRM, Oracle database, SAP, and VDI  Faster warm up and reduced wear compared to competitors  Large SSD cache pool capacity up to 3.2TB (1.6TB per controller)  Wear level information to monitor remaining life expectancy 13

14. Access hot data from SSD Cache Smart firmware design automatically manages SSD Cache pool and copies hot data from HDD to SSD Cache pool Key software feature – SSD Cache Host read request Data is not in RAM, check data hotness record System reads data from SSD Cache pool System reads data from HDD Send data to host Controller memory cache SSD HDD Cache hit No cache hit 14

17. Tier 0 Tier 2 Tier 1 Tier 3 Automated data migration with scheduling options  Bi-weekly automated data migration executed during system off-peak periods  Hot or cold data defined by the system based on access frequency and how old the data is  Newly-created data is always temporarily stored in tier 0 until data migration  Hot data sent to higher tiers and cold data moved to lower tiers after migration  Tier migration priority Users can set up migration priority if host I/O and tier migration are running at the same time Three priority levels: low, normal, high 17 2GB SAS SSD SATA SSD SAS HDD NL-SAS HDD Key software feature – automated storage tiering (4 tiers)

19. Key software feature – self-encrypting drives Disk drives and valuable data can be physically stolen, especially when disposed of Without SED SED technology prevents disk drive data from being stolen even if drives are physically obtained by other parties With SED 19

20. Key software feature – self-encrypting drives Compatibility with SED (self-encrypting drives) delivers unbreakable defense against disk theft or misplacement and also expedites data deletion. Benefits 1)Ease of use and improved efficiency for data encryption 2)Improved system performance (CPU) as encryption workload is moved on to drives directly Great for these applications: 1. Banking 2. Military 3. Government and research 4. Healthcare and critical personal info 20
