    A Hardware Checklist Before a Data Centre Relocation
    在 經過 Tan cheng / 0 評論
    Key Takeaway Most data centre relocation failures do not happen on moving day but at the "first power-on after the move". Success depends on a complete pre-move inventory, offline backup validation, power and cooling budgeting, and item-by-item acceptance after the move.

    A Complete Guide to Bulk Laptop Procurement for Schools
    Key Takeaway When Hong Kong schools procure mobile computer devices, besides specifications and price they must also handle three things: funding and procurement procedures, the device lifecycle (usually replaced every 3 years), and the management of student borrowing. The Education Bureau's Quality Education Fund e-Learning Funding Programme currently runs to the 2026/27 school year (Education Bureau Circular No. 73/2026), provides a standard application and replacement process and supplies procurement document templates; schools should write "trade-in" clauses and asset disposal arrangements into the tender documents in advance, and choose models that... 閱讀更多

    Comparing Refurbished, Display and Second-hand Computers
    Key Takeaway The biggest difference between the three lies not in the hardware itself but in the process behind the seller: display units (open-box) are almost unused returned units that usually still carry the full OEM warranty; refurbished units have been tested, had parts replaced, cleaned and had the system reinstalled, and generally come with a 3- to 12-month warranty; second-hand units (used / as-is) are sold as-is, usually with no testing and no warranty. What an enterprise is buying is "process and warranty", not "cheap hardware". Key Comparison Item... 閱讀更多

    What Is the Difference Between New Factory Stock and Parallel Imports?
    Key Takeaway "Authorised-channel stock" means goods imported through Hong Kong's officially authorised distributors, while "parallel imports" (commonly known as grey imports) are OEM goods imported outside the official distribution channel. Grey imports are not fakes, but the two differ completely in after-sales service, model versions and power-plug compliance. In Hong Kong, selling non-compliant grey-import electrical appliances may violate the Electrical Products (Safety) Regulation; enterprise procurement should pay particular attention to warranty, parts supply and compliance risks. Key Comparison Item Authorised-channel stock (official distributor) Parallel import (grey import) Import Channel Through... 閱讀更多

    How Should a Hong Kong Company Choose a Network Switch?
    Key Takeaway The three decisive numbers are port count and total PoE power budget, uplink speed, and management mode. The most common mistake in Hong Kong offices is an insufficient PoE budget (treating "power per port" as "total power"), followed by connecting Wi-Fi 7 access points over 1G-only uplinks. Also note that subscription-based licences (such as Meraki) disable the equipment's features once they expire, so subscription fees must be counted into the TCO before purchase. Key Comparison Standard Name Power Per Port Typical Use IEEE 802.3af PoE 15.4W Older VoIP... 閱讀更多

    How Do Enterprise-Grade SSDs Differ from Ordinary SSDs?
    Key Takeaway The appearance is the same, the interface is the same and the headline speed may even be similar, but an enterprise-grade SSD adds a set of power-loss protection capacitors (PLP), 3 to 30 times the endurance (DWPD/TBW), a tighter error rate (UBER 10⁻¹⁶) and undiminished sustained write performance. Using consumer-grade SSDs in a server means the money saved in the short term usually comes back several times over in the form of data corruption and premature replacement. Key Comparison Comparison Point Consumer / Client-grade SSD Enterprise SSD Power-Loss... 閱讀更多

    RAID 0, RAID 1, RAID 5 and RAID 10 Compared
    Key Takeaway RAID 0 is about speed, not safety; RAID 1 is simple and reliable but delivers only half the capacity; RAID 5 offers high capacity efficiency but is no longer recommended on drives above 4TB, because a single unrecoverable read error (URE) during a rebuild writes off the whole array; RAID 10 has the fastest writes and the safest rebuild, at the cost of 50% of the capacity. Whichever level is chosen, RAID is not a backup. Key Comparison Item RAID 0 RAID 1 RAID 5 RAID 10 Minimum... 閱讀更多
