CPU architecture decisions
The Iron-E3 baseline ships with Intel Xeon E3-1245v6, four
cores at 3.7 GHz boost. The E3 platform retains relevance
for workloads where per-core throughput matters more than
core count. PowerMTA at low-to-mid volume, MailWizz with
modest customer counts, single-tenant transactional mail,
general web application servers all fit within the E3
envelope. ECC RAM, server-grade reliability, RAS features
present.
Iron-E5 ships with Intel Xeon E5-2680v4, fourteen cores at
2.4 GHz base, 3.3 GHz boost, 35 MB L3 cache. The E5-v4
platform remains the most economical option for sustained
mid-volume bulk email work. Per-core throughput is lower
than newer Scalable parts but core count compensates;
PowerMTA queue throughput at this configuration sustains
1,500-2,500 messages per second to mixed receiver
destinations.
Iron-EPYC ships with AMD EPYC 7402P, twenty-four Zen 2
cores at 2.8 GHz base, 3.35 GHz boost. EPYC 7002 (Rome)
generation provides the best price-performance ratio in
our current fleet. Sixty-four cores per socket available
on EPYC 7702P configurations for customers needing the
density. PCIe 4.0 throughout, allowing eight-drive NVMe
arrays without bandwidth constraint. EPYC's chiplet
architecture means workloads that fit within a single CCD
(eight cores) avoid cross-CCD memory latency; pinning
processes to specific cores helps workloads sensitive to
this.
For workloads requiring newer silicon (Sapphire Rapids,
Granite Rapids, EPYC Genoa, EPYC Turin), we configure on
request. Pricing scales accordingly; 32-core EPYC 9354
configurations land around €399/month, 64-core EPYC
9554 around €549/month. The mainstream offshore market
has not fully migrated to Genoa/Turin yet because the
price-per-core has not crossed the threshold where it
beats Rome; that crosses through 2026 and we will refresh
baselines accordingly.
Storage subsystem details
All baselines ship with NVMe storage. NVMe-only fleet
since 2023; we deprecated SATA SSD and HDD options
because the price-performance gap closed and operational
consistency improved. Drives are enterprise NVMe
(typically Samsung PM983, Micron 7300 PRO, Intel D7-P5520
depending on stock), rated for 1.0-1.3 DWPD endurance,
PLP (power-loss protection) on all units.
Default RAID configuration is RAID-1 (mirror) for two-drive
arrays. RAID-10 across four drives available as upgrade
(+€90/month including extra drives). RAID-Z and ZFS
configurations supported on FreeBSD and Linux with ZFS
modules; we set them up on request but do not provide
managed ZFS administration. Hardware RAID controllers (LSI
MegaRAID 9460-16i) on EPYC configurations; software RAID
(mdadm) on Intel configurations unless hardware RAID is
requested.
For workloads requiring extreme IOPS, we configure
all-NVMe arrays of 8+ drives. Sequential reads in those
configurations reach 25 GB/s; random IOPS exceed 5M
across the array. The cost scales (eight-drive
configurations sit at €450-600/month depending on capacity)
but the performance ceiling is high enough for serious
database work.
Network architecture per location
Each datacenter hosts its own BGP-announced IP space we
control. We do not sub-allocate from upstream provider
ranges, which means our IP allocations follow our
policies, our rDNS configuration, and our reputation
management discipline. Major locations announce /22 to /20
blocks with IPv4 capacity in the low thousands per region;
IPv6 announcements are /36 to /32 with effectively
unlimited /64 allocations.
Transit upstreams vary by location. Bulgaria runs Cogent +
NTT + Telia (Arelion). Romania runs Cogent + NTT + Telia.
Moldova runs Cogent + NTT. Panama runs Cogent + Telxius.
Hong Kong runs NTT + Cogent + CN2 (China-direct). Singapore
runs NTT + Telia + Cogent. Ukraine runs Cogent + NTT.
Direct peering with Google, Microsoft, Apple at most EU
locations; APAC peering through carriers' existing
relationships.
Default uplink is 1 Gbps per server with traffic policies
per plan (some plans capped at 30 TB monthly, others
unmetered). 10 Gbps upgrade available as €80/month addon.
25 Gbps for high-throughput operations on request.
Multi-NIC configurations (LACP bonding for aggregate
throughput, separate management network) supported on EPYC
and dual-socket Intel platforms.
DDoS scrubbing capacity ranges from 100 Gbps in Moldova
and Panama to 500 Gbps in Bulgaria, Romania, Singapore.
Mitigation runs at the network edge before traffic reaches
your server. L3/L4 mitigation included; L7 (application-layer)
available as €49/month addon. For sustained large-scale
attacks, dedicated scrubbing capacity is configurable on
request; pricing depends on attack profile and capacity
required.
Operational practices
Hardware monitoring runs continuously. Disk SMART metrics
polled every 60 seconds. RAID array health monitored via
out-of-band controller telemetry. CPU thermal sensors
read continuously; alarm thresholds trigger before silicon
throttling activates. ECC RAM events logged; correctable
errors above threshold trigger DIMM replacement. NIC link
state, transit utilization, packet loss tracked. PSU
health monitored via IPMI sensors.
Customer notifications happen through Telegram and email.
Maintenance windows scheduled with 72-hour notice
minimum, generally during regional low-traffic windows
(02:00-06:00 local). Emergency maintenance (responding to
active hardware failure) initiated immediately with
customer notification within 15 minutes of action. Status
page reflects ongoing maintenance and recent incidents;
historical data available going back 12 months.
Backup is customer responsibility by default. We do not
run backup of customer-owned servers. For customers
wanting managed backup, we offer Backup-as-a-Service
addon (encrypted offsite backup to second jurisdiction,
€19/month for up to 500 GB). Recovery testing on request.
