A blade server system is a chassis that shares power, cooling and network connections between many thin server modules. In India, the refurbished blade systems you will meet most often are Dell PowerEdge M-series in the M1000e chassis, HPE ProLiant BL-series in the BladeSystem c7000, and IBM BladeCenter HS23 blades. The chassis matters as much as the blades, so buy and check them together. This guide explains what each family offers, which published limits to plan around, and how to check a used blade system before you pay. It is written for IT managers comparing refurbished blade servers with rack servers for virtualisation, VDI or scale-out work.
Blades save rack space and cabling when you need many identical servers in one place, for example a virtualisation cluster, a VDI farm or a scale-out application tier. They are less attractive for one or two servers, because the chassis is a fixed cost. For small deployments a rack or tower server is usually simpler: see our guide to blade vs rack vs tower servers, and Serverwale's tower servers and refurbished rack servers pages.
| Chassis | Published blade capacity | Blades listed on Serverwale’s blade page | Source |
|---|---|---|---|
| Dell PowerEdge M1000e | 10U enclosure; up to 16 half-height blades, 8 full-height blades or 8 sleeves of quarter-height blades, or a mix | PowerEdge M630 (half-height; one or two Intel Xeon E5-2600 v3 or v4; 24 DIMM slots; also supported in the PowerEdge VRTX); M640 listed by Serverwale | Dell M1000e owner's manual and technical guide; Dell M630 owner's manual |
| HPE BladeSystem c7000 | 10U enclosure; up to 16 half-height blades, 8 full-height blades and/or 8 expansion blades, not exceeding 16 total; up to 4 redundant interconnect fabrics | ProLiant BL460c Gen8 and Gen9 | HPE c7000 product information reference |
| IBM BladeCenter (now Lenovo documentation) | BladeCenter E: 14 bays; H: 14 bays; HT: 12 bays; S: 6 bays | BladeCenter HS23 (single-wide 30 mm; up to two Intel Xeon E5-2600; 16 DDR3 DIMM sockets; up to 512 GB with 16 x 32 GB RDIMMs) | Lenovo Press HS23 product guide (withdrawn product) |
Two practical notes from those sources. On BladeCenter E the HS23 is not supported with power supplies smaller than 2000 W, and the number of HS23 blades you can fit can be lower than the bay count depending on processor power. On the M1000e, Dell lists 2700 W and 3000 W AC power supply options; the 3000 W unit is specified for 200 to 240 V AC input, which matters for your power feed. Always confirm the exact configuration of the unit in front of you.
A blade without a working chassis is a paperweight, so ask for this list in writing:
Read the chassis serial and each blade serial from the label and from the management controller, then run the manufacturer’s lookup. Dell uses a Service Tag, HPE a serial number in the HPE Support Center, and IBM blades are checked through Lenovo with the machine type and serial. Our guide on how to check server warranty by serial number walks through each brand, and the post-delivery testing checklist covers what to test on arrival.
A fully loaded chassis concentrates load in 10U, so check the circuit, PDU and cooling before ordering. Our hub guides on UPS sizing, rack PDUs, cooling and airflow and rack unit sizing explain the arithmetic. Processor choice also affects power and licensing, so see the Intel Xeon processor price guide and the per-core vs per-socket licensing guide.
Serverwale states that it supplies refurbished blade servers and chassis to buy or rent across India, either blades for an existing chassis or a complete system, with a 1-year hardware warranty and extended warranty for 2 additional years available at extra cost. Renting is worth considering for a short project or a proof of concept before you commit to a chassis; see server rental in Delhi and the server on rent guide. After warranty, an annual maintenance contract keeps the chassis supported. For help sizing, contact the enterprise solutions team, compare cost with the refurbished server price index, or browse live stock.

Both are 10U enclosures. Dell lists up to 16 half-height blades, 8 full-height blades or 8 sleeves of quarter-height blades, or a mix, for the M1000e. HPE lists up to 16 half-height blades, 8 full-height blades and/or 8 expansion blades, not exceeding 16 in total, for the c7000.
Yes, if you already own a compatible chassis. Serverwale states that blades can be bought for an existing chassis or as a complete system. Confirm that the blade model and generation are supported by your chassis and its management firmware before ordering.
No. Dell's owner's manual describes the M630 as a half-height blade supported on both the PowerEdge M1000e and the PowerEdge VRTX enclosure, with one or two Intel Xeon E5-2600 v3 or v4 processors and 24 DIMM slots.
Lenovo's product guide lists BladeCenter E, H, HT and S as supported, and not the BladeCenter T. The number of HS23 blades per chassis can be lower than the bay count depending on processor power, and BladeCenter E needs power supplies of at least 2000 W.
Read the serial number from the label and the management controller, then use the manufacturer's lookup: Dell Support with the Service Tag, the HPE Support Center Warranty Check with the serial, or Lenovo's warranty lookup with the machine type and serial for IBM blades (confirm the product line is covered). Older units are often out of manufacturer warranty, so compare the seller's own warranty.
Buy when you need a long-running cluster and will use most of the chassis. Rent for a short project or to test a design first. Serverwale states that blade systems are available to buy or rent across India.
