The BIG upgrade for my LAB!!!!!
There are three main Hardware components you need to consider for distributed computing, private and or public clouds. The software is a different topic! This article will not go deep into discussion of the compute nor network. Just a specific aspect of shared storage.
I want to discuss option 3. Storage, for most average users the magic that is storage will be local device storage. aka DASD (Direct Attached Storage Device). The world of computing has changed and performance of storage is now 10x or more. You no longer have 4200 rpm drives of spinning rust! Solid state drives (SSD) and even NVMe in different form factors. You have lots of options for performance SSD, NVMe.
That is fantastic right? Well yes and no. Yes performance is fantastic and most applications will take advantage of this upgrade. However the use case that is first of mind for most IT professionals is having shared storage for distributed computing or more flexible shared storage for use with more than 1 computer.
One of the best turn key solutions on the market is Synology. There are three main form factors: Desktop (DiskStation), All-Flash (FlashStation) and rack-mount (RackStation). For me I was provided an evaluation unit for testing. It is huge upgrade from what I had previously purchased on my own. Synology Disk Station DS413J. The test unit is a Synology DS1621+
This is a world class Network Attached Storage (NAS) Appliance. The main distinction for a NAS vs a SAN. NAS uses Ethernet medium for file and access protocols. It does not use a dedicated Fabric Network, so less expense of not using host HBA and less complex to setup. But that doesn’t mean you have slow access to your data. Multiple 1 GigEthernet and even 10Gig/ 25 Ethernet. [10GbE SFP+ / RJ-45 and 25GbE SFP28 NICs] You also have support for Link Aggregation: Dynamic, Active/ Passive, Balance and Adaptive Load Balancing.
The naming convention to help those new to Synology:
DS = DiskStation
21+ = late 2021
6 = number of drive slots (**not including expansion units)
96TB total with 16TB x 6 drives!!
** Easy Storage Expansion
Scale-up on-demand to 16 drives with two DX517 expansion units
Based on manufacture date there are a lot of updates.
More drive slots, more flexible RAID protection but Synology uses Tradition RAID, JBOD and Synology Hybrid Raid (SHR). Depending on your tolerance for fault and drive rebuild AND capacity. Choose the best option. There are a tons of available support RAID types and more flexible with more slots. I have configured 3 drives for now and have chosen SHR. Reference: https://kb.synology.com/en-id/DSM/help/DSM/StorageManager/storage_pool_what_is_raid?version=7
The Combination of Capacity of drive + number of drives + RAID type will yield lots of flexibility.
FLEXIBLE, FLEXIBLE, FLEXIBLE!!!!
Supported Network Protocols:
SMB, AFP, NFS, FTP, WebDAV, CalDAV, iSCSI, Telnet, SSH, SNMP, VPN (PPTP, OpenVPNTM, L2TP)
For the vExpert Home lab.. this is a very reliable and easy to setup solution. Block or File? Yes!!
