Guangzhou Enterprise Server Repair Service

A minute of server downtime can cost thousands or even tens of thousands of RMB. We provide 7×24 server hardware support, covering mainstream brands such as Dell, HP, Lenovo, Inspur, Huawei, etc. We can locate and replace key components such as motherboards, power supplies, fans, RAID cards, and memory.

Typical scenario:Server failure to boot, repeated restart, hard drive failure alarm, array card error, abnormal power supply, and hardware alarms spotted during a room inspection. On-site and remote (IPMI/iDRAC) support, both diagnostic modes.

Core principles:Any operation involving storage, data protection will always be given priority. Evaluate array status before maintenance, and take a full image before starting if necessary; replace spare parts on site and complete power-on test. Guangzhou Urban area will arrive within 2 hours, and Panyu/Nansha enterprise customers will be given priority.

RAID array is a centralized carrier of enterprise business data. Once it crashes, it often affects the whole business line. We can handle RAID 0/1/5/6/10 single disk drop, multiple disk failures and array card damage. In the cleanroom environment, we can mirror disk by disk through professional equipment, and then parse array parameters and reorganize data distribution to recover business data to the maximum extent.

Typical scenario:Server failure to start, array error degradation, multiple hard drives offline at the same time, virtualization platform storage abnormalities, and data loss of key systems such as ERP, finance, hospital HIS, surveillance video, etc.

Process flow:Please do not force online, rebuild array or initialize after failure. Contact us for free diagnosis after power failure. We do read-only mirror one by one, without touching the original disk. We charge after confirming the recovery result. If the recovery is unsuccessful, there is no charge. For key business, you can go through the urgent channel and sign a confidentiality agreement.

NAS and SAN are centralized storage places for enterprise data. Once a failure occurs, it often affects the reading and writing of the entire business system. We undertake the maintenance of NAS such as Synology and QNAP and SAN storage such as EMC and NetApp. We can handle system crashes, storage pool degradation, hard drive offline, fiber channel outages and other failures. We also provide controller replacement, firmware repair and data migration services.

Typical scenario:NAS fails to boot or log in abnormally, storage pool status degradation alarm, volume read-only caused by hard drive disconnection, database non-response caused by SAN fiber link interruption, old storage life will need to be migrated as a whole, etc. Both file-sharing NAS and block-level SAN hosting databases are handled according to the same data-first process.

Process: For all storage-related operations, evaluate array and volume status first, mirror if necessary, and then repair or replace. We support file system-level repairs such as Btrfs, ext4, and ZFS. Storage expansion and online migration can be completed without business interruption. After repair, we provide status reports and follow-up inspection suggestions to avoid recurrence of similar failures.

Server systems are the foundation for enterprise business software, and hidden dangers at the system level are often more hidden than hardware failures. We provide installation, deployment, patch management and troubleshooting of mainstream systems such as Windows Server and CentOS/Ubuntu, covering the construction and daily operation and maintenance of virtualization platforms such as VMware ESXi and Hyper-V, so that every physical server and virtual machine is in a controlled state.

Typical scenario:ERP/OA/database and other business systems are stuck or have abnormal service, system logs report errors, patches are missing and there are security vulnerabilities, new servers need to be built from scratch, old servers are short of resources but cannot be offline, etc. Whether it is a single server for SMEs or a multi-node virtualization cluster, we can provide symptomatic solutions according to the existing scale.

Our commitment:Continuous monitoring and location of performance root causes through CPU, memory, disk IO, network traffic and other indicators, followed by kernel parameter tuning, service streamlining and resource isolation. Measurement can significantly reduce load and shorten response time. Support per-service and annual O & M contracts. Contract customers enjoy regular inspection and 7×24 response, and inspection reports are kept for future reference.

Server network performance and security directly affect business experience. We provide Teaming/Bonding to improve bandwidth and redundancy, Load Balancer (SLB) to distribute traffic, firewall and ACL security policy configuration, and VPN remote access to make off-site office safe and convenient.

Typical scenario:Large traffic needs to be distributed, multiple network cards need to be highly available, remote employees need to access the intranet safely, servers exposed to the public network need to be reinforced, and VLAN division and traffic isolation needs to be implemented.

Change and Delivery:All network changes are verified in the test environment first, and then implemented according to the agreed change window. The fallback scheme is prepared in advance to ensure zero service interruption. Complete configuration documents and network topology diagrams are provided after configuration, facilitating subsequent O & M and fault location.

Instead of fighting fires after failures, it is better to do O & M in normal times. Server maintenance contracts cover quarterly/annual regular inspection, 7×24 fault response, rapid replacement of spare parts and O & M reports, covering mainstream brands such as Dell, HP, Lenovo, Inspur, Huawei, etc., turning uncontrollable downtime risks into predictable service guarantees.

Suitable for:SMBs without dedicated IT, companies that rely on critical systems such as ERP/databases, and customers with multiple servers that need to be centrally managed. Contract scope can be flexibly tailored to the number of devices and response levels.

What we do:The inspection report covers hardware health, RAID array status, system log analysis and expansion suggestions; priority response during the contract period, maintenance cost discount, remote response within 30 minutes, on-site arrival according to the agreed time limit. It has served dozens of enterprises in manufacturing, medical, education and other industries, and the renewal rate exceeds 90%.
