Dell PowerEdge R730 Virtualized SQL 4-node Cluster.SQL Server OLTP Benchmark Factory LoadGen Equipment Storage Footprint: 600GB allocated, 500GB used.SQL Server Testing Configuration (per VM) While our traditional usage of this benchmark has been to test large 3,000-scale databases on local or shared storage, in this iteration we focus on running out four 1,500-scale databases on the NAS over iSCSI. This test uses SQL Server 2014 running on Windows Server 2012 R2 guest VMs, being stressed by Dell’s Benchmark Factory for Databases. While our Sysbench workloads tested previously saturated the platform in both storage I/O and capacity, the SQL test is looking for latency performance. From a system resource perspective, we configured each VM with 16 vCPUs, 64GB of DRAM and leveraged the LSI Logic SAS SCSI controller. Along the bottom (from left to right), is the Kensington Security Slot, the first eSATA port, four LAN ports, the reset button, three USB 3.0 ports, and the second eSATA port.Įach SQL Server VM is configured with two vDisks: 100GB volume for boot and a 500GB volume for the database and log files. To access to the PCIe slot, simply remove the screw and pull open the cover open. Surrounding the fans is the PCI Express Expansion Slot (right) and the power port (left). The dual fans take up the majority of the back panel’s real estate if one the fan malfunctions, you will hear a loud beeping sound. RAM is accessed through the bottom of DS1517+ by removing the bottom panel’s four screws. Synology branding is located on the sides of the NAS and double as ventilation. At the bottom right is a USB 3.0 Port Connect, where users can connect external hard drives, USB printers, or other USB devices to the DS1517+. Followed by these LEDs are the power button and the LAN indicator, the latter which displays the status of the network connection. Along the top are the Status indicator and Alert indicator, which displays the status of the system and warnings related to fan or temperature, respectively. All 5 drive-bays, each of which have a drive lock and status indicator, are visible and easily accessible. There is also a good amount of functionality on the front panel surrounding these drive bays. The DiskStation DS1517+ is a compact NAS, featuring a high-quality plastic enclosure with a nice matt-black finish. Power Frequency: 50/60 Hz, Single Phase.AC Input Power Voltage: 100V to 240V AC.Brightness adjustable front LED indicators.Size (Height x Width x Depth): 166 mm x 250 mm x 243 mm.M2D17 – Dual M.2 SSD adapter card for SSD cache.RJ-45 1GbE LAN Port: 4 (with Link Aggregation / Failover support).Maximum Raw Capacity with Expansion Units: 150 TB (10 TB HDD x 15) (Capacity may vary by RAID types).Maximum Internal Raw Capacity: 50 TB (10 TB HDD x 5) (Capacity may vary by RAID types).Maximum Drive Bays with Expansion Unit: 15.Memory Expandable up to: 16 GB (8 GB x 2).Memory Module Pre-installed: 2GB (1 x 2GB) / 8GB (2 x 4GB).Synology DiskStation DS1517+ Specifications Otherwise, the DS1517+ can reserve two of its bays for read/write caching SSDs, while the other three bays are used for the primary data storage via HDDs.īacked by a 3-year warranty, the Synology DiskStation DS1517+ goes for roughly $745 for the lower end (2GB of RAM and no HDDs). Under RAID5 configuration, a single DS1517+ supports up to 40TB in total storage when leveraging the M.2. The Synology adapter supports 2280/2260/2242 form factors and as well as an array of different M.2 SATA SSD options so you don’t have to buy specific brands. the M2D17) to significantly increase overall system performance. Users can also install a dual M.2 SSD adapter card (e.g. The DS1517+ can be outfitted with hardware to add functionality and performance via the PCI Express Expansion Slot, which is accessed through the back panel, such as a 10GbE NIC to boost network speeds. Synology also quotes speeds of 1,165MB/s and 527.99MB/s in sequential reading and writing, respectively, and can be expanded from 50TB to a maximum of 150TB using 15 drives via two DX517 expansion units. Powered by a Quad-core 2.4GHz CPU with AES-NI hardware encryption engine, the DS1517+ comes equipped with quad 1GbE LAN ports and up to 16GB DDR3 RAM (dual channel). The Synology DiskStation DS1517+ is a 5-bay NAS designed for encryption and intensive tasks.
