In service · DSM 7 incompatible · security clock ticking

Beast of a machine for 2013 — 8 bays, 4 NICs, ECC RAM, expandable to 18 bays via DX513 expansion. Twelve years on, it's still capable, but Synology dropped this generation from DSM 7 (released 2021). DSM 6.2.4 is the final supported OS and security updates have wound down. Two pragmatic paths: (1) demote to warm-archive-only on an isolated VLAN with no inbound internet access, or (2) plan replacement within the next 12-18 months. Drop receipts + expansion-unit history + SMART reports below — the more substrate, the cleaner whichever path you pick.

Identity facts

Model

DS1813+ · DiskStation 8-bay Plus series · Synology Inc · Taiwan

Serial number

TBD · read off the rear-panel label (typically 13XXX... prefix for 2013-vintage units). Drop photo into zone below.

MAC addresses (4 NICs)

TBD · capture all 4 from the rear-panel label OR DSM Control Panel → Info Center → Network. Useful for DHCP reservations + access-control allow-lists.

Power input

100–240 V AC · internal PSU · ~250 W max draw under load; ~50-80 W typical operating

Purchase + install

TBD · drop receipt into the zone below to lock the date + retailer

Current location

TBD · note rack/shelf + which switch port(s) it's lit up on

Drives installed

TBD · 8 bays — note capacity per bay, brand, age, SMART status. Drop SMART reports.

DX513 expansion unit(s)

TBD · do any DX513 units extend this? Capacity each, drives installed.

RAID configuration

TBD · Synology Hybrid RAID (SHR)? Traditional RAID 5 / 6 / 10? · usable capacity vs raw · snapshot policy

DSM version

DSM 6.2.4 (final supported) · no DSM 7 path · screenshot current build for the record

RAM upgrade?

TBD · stock 2 GB ECC, max 4 GB. Has anyone added the upgrade module?

Network role

TBD · what it serves (Time Machine? bulk media? off-site backup target?)

Network isolation

⚠ Should be on isolated VLAN with no inbound internet access given EOL status — confirm

Web-sized variant (suffix -web.jpg, ~620 KB, 2000 px wide) drives the photo strip; click the image for the full-resolution original. Still wanted: rear-panel rating plate (for S/N + MAC harvest), DSM "Info Center" screenshot, current Storage Pool layout, any DX513 expansion unit invoices.

Steward actions outstanding

Photograph rear-panel label — captures S/N + all 4 MAC addresses in one go. Drop in zone.
Find original receipt — lock purchase date + retailer + extended-warranty window.
Catalog DX513 expansion units — are any installed? S/N + drives per unit.
Inventory all 8 drives — model, capacity, age, S/N, SMART status per bay.
Export DSM Storage Pool report — Control Panel → Storage Manager → Overview screenshot.
Capture DSM version + last update — Control Panel → Info Center.
Document network role — Time Machine? Media? Off-site backup? Both?
Verify VLAN isolation — given EOL, should NOT be on the same subnet as user devices with inbound rules.
Migration target sketch — what's the 12-18 month replacement plan? (Newer Synology / QNAP / TrueNAS / pure-cloud archive.)
Track DSM 6 security patches — once they stop entirely, the unit must come offline or move to warm-archive on an isolated VLAN.
