EonStor DS series software comparison EonStor DS 1000 / EonStor DS 2000 / EonStor DS 3000 Local replication Default included (snapshot, volume copy/mirror) Thin provisioning Remote replication Yes, optional Automated storage tiering (up to 4 tiers) IDR (Intelligent Drive Recovery) Self-encrypting drives SSD Cache

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 Intelligently moves a copy of the most frequently-accessed data from HDDs to SSD Cache. Sequential read data will not be placed to SSD Cache pool Always keep two copies of hot data, in SSD Cache and HDD Simple and intuitive GUI design

automated storage tiering (4 tiers) Key software feature – automated storage tiering (4 tiers) 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 2GB 2GB 2GB 2GB Tier 0 SAS SSD Tier 1 2GB 2GB SATA SSD Tier 2 2GB SAS HDD Tier 3 2GB 2GB 2GB NL-SAS HDD
